Types of whole house water Contaminants

In general, the most common type of contaminants in our tap water is fall into the categories of Sediments, Heavy Metals, Chemicals or VOCs, and Bacteria. The heavy metals can get into our water by naturally or plumbing system. Among the heavy metals, lead is the most common type of contaminant, but copper, arsenic, chromium, cadmium, Nickel, Mercury, Aluminum, Iron are the few other metals that could be contaminant in our tap water. Old pipe line, broken or cracked water line or tank system can also the sources of bacteria, microorganism, fungi, rust, silt, turbidity, and different bad odors. Further again the tap water or line water may also contaminant with chlorine, insecticides, herbicides, pesticides dirt, sand, chloramine, Volatile Organic Chemicals (VOC), cloudiness and fluoride.

What is the effect of the contaminant water

The contaminant water has various effects on our health and on our home equipment. With the heavy metal water system we may experience with staining on the floor, basin, toilet bowls, sinks, bathtubs as well as clothes. Chlorine water has a bad effect on the hair, nails and skin. The skin may be dried and the hair may be dull.

Construction and function of the express water heavy metal whole house water filter

The express water whole house filter is made with high quality and durable 100% food-grade ABS and PCE plastic materials. The system includes pressure gauges, easy release and 1 inch connections for easy adaptability and high flow. The housings are precision fitted to a durable stainless freestanding mount so that we can changes the filter with very easy. The Express Water Heavy Metal Whole House Water Filter has three stages named sediment, KDF and carbon block. Among them the first filter sediment housing is transparent, as result we can see the inside of the filter and know when it needs to be replaced. The 3 stages describe as below:

Stage 1: Sediment

Sediment is the first stage of the express water whole house water filter system. It is made with precision packed food-grade polypropylene microfiber. It has 4 distinct layers to catch the contaminants like sand, rust, and dirt up to 5 microns. The outer layers of this sediment catch the coarse contaminants and the inner layers catch finer particles.

Stage 2: KDF

Kinetic Degradation Fluxion (KDF) filter is the second stage of Whole House System. It is made with catalytic carbon and high purity ionically charged copper and zinc granules. So when the water flow between this filter then occurs a redox (oxidation-reduction) reaction and captures iron, lead, arsenic, mercury, aluminum, sulfur, algae, viruses, hydrogen sulfide, fungi, chlorine, chloramine and controls and inhibit growth of microorganism. This second stage is focused on capturing heavy metal contaminants. Finished with a thermal bonded cap and industrial sealed silicon ring makes it durable and reliable.

Stage 3: Carbon Block

Activated Carbon Block (ACB) is the third stage of the express water heavy metal whole house water filter. It is made with tight packed, laboratory vacuum heated carbon for high capacity filtration. It captures chlorine, Total Organic Carbon (TOC), pharmaceuticals, turbidity, pesticides, and chemicals causing bad tastes and odors. This stage focuses on taste and drink-ability of your water and removing chemicals. Finished with a thermal bonded cap and industrial sealed silicon ring to make sure it’s durable and reliable.

What does a whole house water filter do?

Whole house water filter systems are popular filtering solutions that are currently used throughout the country because they’re effective and produce high-quality water. It can provide clean and safe water for your family to drinking, washing, cooking and bathing. This three-stage whole house filtration system ensures that all harmful chemicals, dirt, and odors are carefully removed from tap water. Each stage of filtration is specifically designed to help your water be pure as possible when reaching the faucet.

How to find the best whole house water filter?

If you want to purchase a whole house filtration system, then you have to consider some factors. These factors include type of filter, micron filter, lifetime, flow rate, Certifications, Installation and maintenance.

Consider the Type of Filter

The filters that are found in the markets are not same type and same quality. At first, we have to consider which specific contaminants are present in the water, and then pick the filter which is effective for that water.

Filter Micron Size

The filter micron size indicates which particles they can remove. Lower micron size filter can remove most of the contaminants. This express water filter can removes the contaminants which particle size is 5 microns or above.

The lifetime of the filter and support

We should consider the filter that can last for a long period of time. The express water given 1 year warranty on all Express Water Systems and the company offers free lifetime support. But you have to change the cartridge after 6-12 month uses or after filter 100,000 gallons of water. The lifetime of filters will depend on the quality of water and number of family member. Usually, the lifetime of the filter cartridge for a four family member is one year. After that, you will need to replace them.

Flow Rate

The flow rate means the amount of water pressure delivered in all areas of the house. You need a system that will deliver fast and steady flow of water in all areas of your house. Generally, most of the household water system has a flow rate from 10 to 20 gallons per minute. The flow rate of express water is designed with 15 gallons water per minute which is great and we won’t notice any drop of pressure at the tap. We can also know the filter performance with the value of the three pressure gauges.

Installation and maintenance

Easy Installation and maintenance consider one of the qualities for any filter. The express water whole house water filter system designed with such a way that we can install it very quickly and easiest way; the entire unit can be installed in less than 2 hours. One the other hand, changing a filter cartridge takes minutes. You can change them easily without the help of a professional.

Certifications

We will find one or more symbols on the packaging of a product; it may be certification or award symbols. The certification like NSF and ANSI means that it was tested by the NSF and ANSI to comply with their rules and regulations. Certification for NSF or ANSI is a crucial factor in your filtration system. The express water whole house filter is NSF/ANSI certified.

Frequently Asked Questions

The main points about the whole house filtration system are described in above. However some question may rise in some users. So among the most frequently asked questions about the water filtration systems are answered below.

Q: Does the whole house filter work with well water?

If the water comes from a private well instead of from the city’s water line, then it is also need filter. Generally, the well water is not 100% pure because the ground itself can be contaminated with dissolved salt like calcium and magnesium, bad odor, microorganism’s etc. Dissolved salt of calcium and magnesium means hard water. If the water is too hard then the filter is not suitable. In these cases you need another filter like reverse osmosis system. So be sure to check your water quality before choosing a system for well water.

Q: Will a whole house filter remove or reduce Fluoride?

No, the express water whole house water filter would not remove or reduce Fluoride.

Q: Do I need a separate storage tank for the system?

You do not need a separate storage tank for this system because it is an in-line filtration system.

Q: Will this system remove dissolved calcium and magnesium salt?

The express water whole house filter system does not remove dissolved calcium and magnesium salt. The water that contains dissolved calcium and magnesium salt are hard water. To reduce hardness you need another filter like reverse osmosis system.

Q: Will this kill bacteria like coliform?

No, the express water heavy metal whole house water filter does not kill bacteria like coliform. You will need a UV light to kill bacteria. Install the UV light after the filtration.

Swimming pool start up kits

Tasrik Leave a comment

Swimming pool start up kits are the most important chemicals for any pool owner. After the winter season when the weather is starting to warm up or when we fill up new pool for the first time both cases these kits plays an important rule; it is not a matter whether it is in ground or above ground pool or intex pool. Without water balance the pool water isn’t quite ready for swimmers. The correct pool start up chemicals make the pool is free of any potentially harmful contaminants and will protect the swimmers. These chemical contains total alkalinity controller, pH, hardness, sanitize, stain prevention products, algaecides, clarifiers and Sun Sorb. Together, all of these chemicals will clean, clear and safe pool water and therefore we can jump into the pool and start to enjoy the swimming. The following top 10 pool opening tips should be taken by the pool owners which is very easy to do.

Swimming pool start up kits

Step-1: Taking Off Pool Cover

If the pool is an existing pool and having a winter cover then remove it carefully because it may have some amount of water and debris on the cover. So before uncover the pool you should remove the water and debris. After removes the water or debris uncover the pool carefully so that it may not fall into the pool, if some amount of water or debris fall into the pool then it does not a matter because the pool will be thoroughly cleaned. After removing clean the cover properly and store in a safe zone like a basement, garage, storage shed so that it does not damage in summer season and you can use for the next winter season.

Step-2: Reconnect the Equipments

After removing the cover, it is time to reconnect all the equipment which are disconnected before the winter season. The equipment may be pool filter, pump, ladder, pool cleaner or other accessories. Then lubricate all the machinery where needed.  It is very important for the equipment keeping safe and proper working position.

Step-3: Test the Water

This step is need for both the new pool and winterization pool. In this step test your water by using test kit. It is important to test the water for total alkalinity, pH, Chlorine, hardness and stabilizer levels and use the Swimming pool start up kits step by step. You should take the water samples from different point below from the surface of water and average the result for better one. It will help you which chemical you have to use. Never add the chemicals before test the water.

Step-4: Test the Total Alkalinity

After completing the water test, we have to balance the water by adding chemicals. Firstly we should have to balance the alkalinity because it will help to adjust the other parameter in normal range. Alkalinity measures the concentration of free alkaline substances in the water. The proper levels for total alkalinity range from 80 to 120 ppm. If the alkalinity is high then we can lower it by adding an alkalinity decreaser like sodium bisulfate. On the other hand if the alkalinity is low then we can raise the total alkalinity by adding an alkalinity increaser like sodium bicarbonate.

Step-5: PH adjustment

Once we adjust the total alkalinity then we can begin to adjust to other parameters like pH adjustment. The pH is the determination of the acidity or alkalinity of the water. pH means hydrogen ions molar concentration in a solution. The pH ranges from 0 to 14 where 0 means more acidic and 14 means more basic. The pool water pH level should be adjusted from 7.2 to 7.6. To increase the pH we can add soda ash whereas to decrease the pH we can use pH decreaser like muriatic acid and sodium bisulphate.

Step-6: Calcium Hardness

Pool calcium hardness means the amount of calcium ions concentration in water express as CaCO3. Both high and low levels of calcium hardness create problems in swimming pool. The perfect level of calcium hardness in pool water is 150-350 ppm. if the calcium hardness is very low then we can raise this by adding hardness increaser chemicals like calcium chloride. On the other hand if the calcium hardness is very high then we can decrease this by several way such as dilute the water, hardness reducer. For more information you can see the article “Pool calcium hardness increaser and reducer”.

Step-7:  Brush and Vacuum

After the winter season a remarkable amount of dirt and debris may contain in pool water. It can be a source of algae and bacteria. So before the sanitization it is good idea to give the pool a thorough brushing and vacuuming. It will helpful to eliminate algae spores. During brushes it is important to brushing all the point of the pool. Now run the filtration system and circulate the water for at least 8 hours or overnight but it is better to circulate the water for 24 hours. It also helps spreads pool chemicals evenly.

Step-8:  Sanitize the Water

After circulate the water next step is to shock or sanitize the pool water. Chlorine used as a sanitizing chemical of water. This chemical help the swimmers from getting rid of bacteria, algae growth, dirt, debris and other unwanted water contaminants that may have entered into the pool during the winter season and keeps the water clean and safe. There are several types of pool chlorine such as gaseous, liquid chlorine, tablet chlorine, granular chlorine and powdered chlorine are used in swimming pool. Calcium hypochlorite is the most common type sanitizing chemicals. Cyanuric acid used in swimming pool as a chlorine stabilizer. It is known as CYA. After adding the chlorine leave the pool for overnight then retest the pH and calcium hardness, adjust these two parameters if necessary.

Step-9:  Prevent Algae

If After socking the pool, it is time to start treatment for algae. The most common question from swimming pool owners are that “how to remove algae from pool water”. They are single-celled microscopic organisms that grow quickly in the right conditions. They will create some problem like slime, odor, discolor the water which looks ugly. By keeping pool chemistry at right stage you can prevent their growth. A wide variety species of algae are found in the world. Properly swimming pool water maintenance (including regular circulation and filtration) and keeping minimum sanitizer levels will prevent any algae spores entering the pool water. The most common type swimming pool algaecide are copper sulphate, chelated copper-based products, quaternary ammonia, benzalkonium chloride and simazine.

Step-10: Metal Stains

During winter season, the metal such as manganese, iron and copper can build up in pool water and can lead to discolor the water. The metal may enter in pool water through by chemicals, pool equipment and plumbing or poles, toys, and tools that are fall into the water. Moreover, fresh water is also an important source of metal in pool water. Higher level of metals can create stains on swimming pool. To remove metals you can follow the methods that are described in the article “Problems of iron and copper in pool water”.

To balance the water, use this swimming pool start up kits in a regular basis. It will keep your water and the pool in good condition.

P alkalinity and M alkalinity

Tasrik 2 Comments

Alkalinity is an important measurement for most of the treated water like drinking water. P alkalinity and M alkalinity are the most useful test. They also have known as P value and M value respectably. The neutralize process of alkaline water by acid is refers to the alkalinity. It is directly related to water hardness. This alkalinity values guidance us to applying proper doses of chemicals during water treatment. The salts of carbonate, bi-carbonates, borates, silicates, phosphates and free hydroxyl ions are responsible for alkalinity of natural water. Among of them hydroxyl ions, carbonates and bi-carbonates are the main factor. The P alkalinity and M alkalinity of water are determined by how much acid is taken to lower the pH to the specific value. The result can be expressed as mg/l CaCO3.

P alkalinity and M alkalinity

P alkalinity test

P Alkalinity is the alkalinity that is determined by using phenolphthalein indicator. This alkalinity is easily measured by titration with a standard solution of N/50 sulfuric acid. During the experiment the water is taken in a conical flex and the acid is taken in the burette. The endpoint pH range of the phenolphthalein indicator is 10-8.3. The neutralization process decreases the pH of the solution and the endpoint changes the color from pink to clear. Some water may not have P value. When the phenolphthalein indicator added into the water then the clear solution indicates the absence of P value.

M alkalinity test procedure

M Alkalinity is the alkalinity that is determined by using Methyl orange indicator. To measure this alkalinity, take 50 ml sample water into a conical flask. Then add 2-3 drops Methyl orange indicator and titration with a standard solution of N/50 H2SO4 solution. The endpoint pH range of the Methyl orange indicator is 4.3 to 3.1. At the end point the color of the Methyl orange changes from yellow to orange (in acid medium it is red color). Take the burette reading and calculate M value by the following equation.
M value = Burette reading (in ml) × 1000/50 ppm

Sl Sample volume (ml) Burette reading (ml) Result (CaCO3 mg/l)
1505100
2506120
3505.5110

Normally, we test p value and M value with the one sample. In this case firstly, we measure P alkalinity using phenolphthalein indicator (say Burette reading ‘A’). Just after the test of P value, we added Methyl orange indicator and complete the titration (say Burette reading ‘B’). For M value calculation, the Burette reading will be (A+B).

This test result indicates the type of ions that are present in the water. It may be present as carbonate, bi-carbonates, and hydroxide.

Condition HydroxideCarbonateBicarbonate
P = 0NoneNoneM
P = MMNoneNone
P = 1/2 MNoneMNone
P < 1/2 MNone2PM – 2P
P > 1/2 M2P – M2(M – P)None

M alkalinity is also known as total alkalinity. The p alkalinity and m alkalinity is useful for research, boilers water, cooling water, pool water treatment etc.

Ammonia removal from water

Tasrik Leave a comment

Ammonia is a nitrogenous compound. It effects on aquatic life directly or indirectly. So ammonia removal from water is very essential. It dissolves easily in water and produced ammonium hydroxide solution. Ammonia is a colorless gas and it is very irritating. Depends on pH level ammonia can present in water in two form; either in ammonium hydroxide form or ammonium salt form. When the pH level is less than 7, then the ammonia is present in water as ammonium salt form. It is relatively nontoxic form. On the other hand, when the pH level is above the 7, then the ammonia is present in water as ammonium hydroxide form. Relatively it is toxic form of ammonia.

Sources of ammonia in water

Ammonia is one of the most widely produced chemicals in the USA or earth for industrial purposes and as fertilizers. Moreover, it has many natural sources like decomposition of organic waste, animal and human waste, fish feed, nitrogen fixation process, forest fires etc. They can enter into the aquatic environment via direct or indirectly; for example, municipal effluent discharges, runoff from agricultural land.

Ammonia removal from water

Effects of ammonia in water

If the ammonia level is high in water, it may difficult to aquatic life. It may responsible to the death of fish. Ammonia effects to internal tissue and production systems of the fish. Fish are unable to extract energy from feed efficiently and becomes sluggish. Eventually, they fall into death.

How to remove ammonia from water

You cannot remove ammonia from water by usual water treatment process. It can be removed by different ways like ion exchange, distillation, reverse osmosis or boiling. Some of them are expensive.

Boiling process

You can reduce ammonia by boiling the water for about 20 minutes. This process has some problems. It can remove free ammonia only but cannot remove the dissolved or ionized forms of ammonia. Moreover, it is suitable for drinking water but not suitable for large scale like ponds.

Ion exchange ammonia removal

Ammonia can be removed by cation resin. In this case sodium ion will replace the ammonium ion. If the water is soft then this is fine process. But if the water has hardness, then this process can creates problem, because calcium and magnesium ion can has simultaneous affinity; these two ions also removed by sodium ion.

Reverse Osmosis

It effectively removes chloramines but does not remove ammonia effectively. But resin containing post-filter cartridge can remove ammonia effectively. In this case reverse osmosis removes hardness, so cation exchange resin can removes ammonium ion perfectly as calcium and magnesium ion does not interfere.


Activated carbon

Activated carbon can removes chloramines. It is suitable for small scale like aquarium water, drinking water or swimming pool water. Chloramines comes into water because people use chloramines directly or chlorine as disinfectant. On the other hand it is not effective against ammonia.

Zeolite Process

Zeolite can reduce ammonia in tiny project finely, but it is not suitable for continuous process. So you can use it in aquarium but not for drinking water plant.

pH reduction process

We know, at lower pH (below 7) ammonia exists as relatively nontoxic form. So when the pH is higher, then we can shift the ammonia equilibrium to the nontoxic form.

Carbonated water

Tasrik 1 Comment

The carbonated water will produce when the carbon dioxide gas dissolves in the water either artificially with under pressure or natural geological process. The process of dissolving carbon dioxide is known as carbonation. Naturally carbon dioxide dissolves in water at very low concentration, but under pressure and low temperature it will be increased. When carbon dioxide dissolved in water it will produces carbonic acid.

H2O + CO2 ⇌ H2CO3

It is colorless, odorless, tasteless and a clear liquid. It can be mixed with different kinds of chemical such as citric acid, sodium citrate, sodium chloride, sodium bicarbonate, disodium phosphate etc. to improve the taste. So it has variation. We found the carbonated water in the market as different form such as soda water, club soda, sparkling water, seltzer water etc. Unmixed carbonated water is a refreshing and good alternative to sweetened soft drinks. It should not contains extraneous matter like nitrogen dioxide, sulphur dioxide, hydrogen sulfide etc.
Carbonated water

Carbonated water health effects

Carbonated water is slightly acidic. The pH value of it is 3-4. If it is not mixed with other ingredients, then it is little impact on health.

Carbonated water side effects

Dental Health

It is said that carbonated water effects on teeth. There is very little evidence on the favor of the topic. If you consume it for a long time then it can damage enamel slightly compare to pure water, as it is slightly acidic. But soft drinks are about 100 times more erosive to teeth; as it has huge sweetened ingredient.

Bone health

Although the carbonate water is blame for bone losses, but there is no paper that suggest the plane carbonated water is responsible for bone damages. The carbonated beverage can responsible for bone losses because it has more sweeteners. Moreover the cola drinks use phosphoric acid which can loss calcium from the bone.

Irritable bowel syndrome (IBS)

It is also said that carbonated water can increase Irritable bowel syndrome (IBS) due to it release carbon dioxide gas in the stomach. Therefore if you experience this problem then you should quit this water.

Weight gain

Weight gain is another question against carbonated water, but plain carbonated water does not responsible for weight gain. We know that this water can mixed with many types of ingredients which can responsible that; for example the sweetened carbonated water like soft drinks may contribute to weight gain.

Carbonated water benefits

If you consume this water after food, then it will remain for long time in your stomach, so you can feel of fullness after meals. Carbonated water may benefit for digestion system. Moreover, it will improve the constipation and indigestion.

Carbonated water uses

Carbonated water is a popular refreshing drink. It is consumed directly or mixed with other ingredients to produce popular drinks like fruit juice, beverages, soda water, seltzer water, tonic water, sparkling water etc. Beer, wine and champagne are naturally carbonated drinks.

Seltzer water

Seltzer water is just plain carbonated water. People take it as a refreshing taste. Some seltzer water company may add flavors. The word seltzer comes from the German town seltzers named.

Soda water vs carbonated water

Soda water means the carbonated water where sodium ingredients like table salt, sodium or potassium bicarbonate are added. It is one of the popular drinks among the adult.

Silicic acid in water

Tasrik Leave a comment

Silicic acid is a very weak acid. It is the compound of silicon, oxygen and hydrogen. Silicon is not found in free form in the nature. Mostly it is found in the nature in oxide form. Usually, oxides of silicon are very little soluble in the water whereas the others silicon compounds are insoluble in water. The solubility of silicon dioxide creates silicic acid. Little amount of silicic acid is not harmful to our health; rather it is benefits to our health. On the other hand it is responsible for scaling in boiler. It is also known as ortho silicic acid. The chemical formula of silicic acid is H4SiO4 or Si(OH)4. It makes colloidal system in the water.
Silicic acid in water

Silicic acid solubility in water

Silicon dioxide dissolved in water very slowly. One molecule silicon dioxide absorbed two molecules water and makes one molecule silicic acid in water. Conversely, silicic acid is an unstable compound in water medium, it breaks and creates silicon dioxide and water. So both the compound makes and equilibrium condition which is as follow:
SiO2(s) + 2H2O(l) ↔ H4SiO4(aq)
It has a water solubility of 0.12 g/l. The solubility will depend on temperature and pH. It increases with the increased temperature and pH. The ionic condition of the silicic acid is as below:
H4SiO4(aq) ↔ H3SiO4– + H+

Silicic acid benefits

Silicic acid plays an important rule for our body. It removes toxic aluminium from our body through the urine which is responsible for Alzheimer’s disease. Moreover, the deficiency of silicon may leads to pale and wrinkle skin, brittle nails and hair. In addition, it also improves bone formation, joint health, preserve dental health, and stimulate digestion. So we should drink silicic acid containing water.

Disadvantage of silicic acid in water

The plant which produces steam for many purposes, are unsafe to use silicic containing water. It is responsible for many boiler disturbances. It can create scaling in boiler and its tubes. Therefore the boiler performance and boiler life will be reduced due to scaling. We will get poor heat transfer. To get sufficient steam, we over heat the boiler tube. Hence the effectiveness of the boiler will be decreased and the fuel and maintenance cost will be increased.

Removal of silicic acid from water

Silicic acid can be removed from the water by many ways. But these methods cannot remove the silica completely; they can just reduce the amount of this element. Using trivalent ions like iron or aluminum will brings better result than divalent or monovalent metal ions. Sodium aluminate is one of the effective methods to eliminate silicic acid. Aluminium hydroxide is another process to reduce silicic acid. The effectiveness of these processes depends on pH value; the effective pH value is 7.0 to 9.0. More over it is also depends on the ratio of (Ca+mg):Na.

Conclusion

Although the silicic acid in drinking water is good for health, it is not good for boiler water. So when you use silicic acid containing water as drinking purpose, it need not to remove them; but when you use them as boiler purpose, you must remove them before using.

Solvent properties of water

Tasrik Leave a comment

The substances that have ability to dissolve other materials are known as solvent. It can be liquid, gas or solid. Water has excellent solvent properties. It can dissolve a vast amount of substances. Therefore it is called universal solvent. The polar effect (dipole moment) and high dielectric constant properties make the water excellent solvent. It plays an important rule to the entire living thing on the earth. Whenever the water goes to our body, it takes valuable chemicals, minerals and nutrients.

Polarization of water

The water has two different atoms such as oxygen and hydrogen. The oxygen is an electronegative atom whereas the hydrogen is an electropositive atom. Therefore the bonding electrons of the O-H bonds spend more time near to the oxygen atom. Consequently it has an asymmetric internal distribution of charge although they are neutral and uncharged. This creates partially positive charges on hydrogen and partially negative charge on the oxygen. The partial positive and partial negative charges on water molecule can be shown in following way:
solvent properties of water

Dipole attraction of water

This polar property of the water can form electrostatic interactions with other polar molecules and ions. Therefore water can interacts with different charged and polar substances but does not react with nonpolar substances like oils. The positive ions or partially positive charged molecule of a substance feel attraction with the partially negative charged oxygen atom. On the other hand the negative ions or partially negative charged atom of a substance feel attraction with the partially positive charged hydrogen atoms. This is called ion-dipole or dipole-dipole force of attraction. This force of attraction between the water molecules and ions or partially charged molecules is lead to the formation of a three-dimensional hydrated ions, or hydration shell which is lower in energy compare to separated ions or molecules. These hydration shells allow particles to spread out evenly in water. The partially charged water molecule does not remain fixed with a single ions or a molecule which is changed with time to time. So the average number of close water molecules with an ion is called hydration number of that ion. Normally the hydration number of a cation is larger than an anion. On the other hand small and highly charged ions have larger hydration number.

Example of water solvent with ionic compound

For an example we can consider the compound sodium chloride (NaCl), which is an ionic compound. The partially positive charged hydrogen of the water molecules attract to the negative Cl– ion, whereas the partially negative charged oxygen of the water molecules attract to the positive Na+ ion. This force of attraction between dipolar water molecules and sodium chloride ions causes the formation of hydrated ions. As a result the sodium chloride will dissolve with dissociation process and forms a homogeneous solution. Brackish water is a homogeneous solution of sodium chloride. Same way many bio-molecules are either polar or charged.
what is the universal solvent

Solvent properties of water with Nonpolar molecules

Nonpolar molecules, like fats, lipids and oils, don’t interact with water at any considerable level because they have zero dipole moment (no partially charged atoms). They have weak electrostatically force of attraction to water molecules. This weak force of attraction would not overcome the strong force of attraction between polar water molecules. Therefore they stay in two separated layers and known as hydrophobic. Normally they are organic compounds. They are dissolved in some non polar substances like benzene, carbon tetrachloride.

Water Desalination Process

Water desalination process is a system that removes dissolved salt and other contaminant from water in order to obtain fresh water. This water may be used as drinking, industrial or irrigation purposes. This process is used those areas where fresh water is insufficient but unlimited supply of saline water like Saudi Arabia, UAE, USA, Israel, Kuwait, Bahrain, Qatar, Oman, Australia, North Africa. More than 100 countries use the desalination process. Without sodium chloride this water may also contains some other contaminants such as organic matters, biological and mineral contents, algae, calcium carbonate etc. These substances should be removed from saline water. Generally the TDS value of the produce water is less than 500 ppm which is suitable for most of the domestic, industrial and agricultural uses.
sea water desalination

The saline water can be classified as seawater, brackish water, low salinity water and very salinity water. Brackish water has more salinity than fresh water but less than seawater. It can be produced in different ways such as mixing of seawater and fresh water, occur as in brackish fossil aquifers, certain human activities etc.

Type of water TDS value
Fresh water Less than 1000 ppm
brackish water 1000-10000 ppm
Highly saline water 10000-35000 ppm
Seawater Above 35000 ppm

Types of desalination process

There are so many types of water desalination process. It can be achieved by different water treatment process such as membrane process, distillation process, ion exchange, freezing, geothermal process etc. The distillation process can be further classified into multi stage flash distillation, multiple effect distillation and vapor compression. On the other hand the membrane process can be classified into reverse osmosis, electrodialysis, nanofiltration, membrane distillation and forward osmosis. Among them the most of the plants use reverse osmosis processes whereas the multi-stage flash distillation system is in second position.


Here we describe the reverse osmosis desalination process. Mainly the process contains three steps: pretreatment, reverse osmosis, and post-treatment.
Water desalination process

Pretreatment

Pretreatment is very significant step for reverse osmosis. This step is used to remove algae, sediment, suspended solids and other particles and adjusting the pH to increase efficiency of the next reverse osmosis step. It may contain multimedia filter tanks such as sand filter, diatomaceous earth filter or cartridge filters.

Reverse Osmosis

In RO, the pretreated water pumped with high pressure through semi-permeable membranes, therefore the freshwater separated from saltwater by keeping salt and other minerals behind. A Small percentage of salt may remain in freshwater; it may up to 500 ppm. This fresh water is suitable for consumption. On the other hand the water behind the membranes is too much salty which is known as brine. This brine needs to be discharge into the sea by diluation with sea water to reduce the impact on sea. Normally the size of the RO membrane pore is about 0.001 microns.

Post-treatment

The fresh water, after the reverse osmosis is almost ready for uses. It needs to be treated as per consumption. In post-treatment step, it may require pH adjustment, disinfection or degasification before use as potable water. For industrial uses the water needs more pure water.



Desalination pros and cons

Generally the water desalination process requires more energy compared to other processes like groundwater or rainwater treatment. Although the membranes are sensitive but the system is simple and requires low maintenance. The brine disposes very carefully so it has a negligible environment impact.

salt water pool problems

Tasrik 1 Comment

Despite the popularity of the salt water pool in the USA is increasing day by day, but they have some problems. They are not a chlorine free swimming pool. Here Chlorine is produced from the salt water with the help of electrolytic chlorine generator (ECG). These types of pools are popular due to the water is clean, less chlorine smell, lower chloramines formation and low eyes irritation. The common salt water pool problems are scale, corrosion, drainage etc. Comparatively it is not a better pool then a chlorine pool. So you should consider the following problems before installation this type of pool.
salt water pool problems

Salt water swimming pool pH problem or scaling problems

The pH levels are a significant factor among the salt water pool problems. In these system the pH is tends to higher level. Reason, the sodium hydroxide also produces in chlorine generation process which are shown in the following reaction.
H2O + NaCl → HOCl + NaOH
The pool should be run between the pH level from 7.4 to 7.8. The pH over 8.0 can brings bad effects to the pool. It is a favorable condition to create scaling. Moreover, the chlorine may be lock up at higher pH. The scale can damage various parts of the pool. Common scaling components are calcium, phosphate, silicate and sulfates. The mineral deposit on the blades of electrolytic chlorine generator (ECG) can contribute to hamper the effectiveness and life span of the ECG which can lead to premature replacement. It is very costly to replace.


Moreover, the scale can also increase the temperature of the water. The scale on the blade can act as insulator and able to generate heat, so the contact water becomes hotter. On the other hand lower pH also creates problems. It can reduce the chlorine effectiveness, make the water corrosive and build up brown stains on the pool’s surface.

Draining system

Draining system is another problem for salt water swimming pool. Because of many municipalities prohibit to drains the saltwater from chlorine pool into the local sewer system. This water is harmful to plants, lawns, environments etc. Therefore they encourage the pool owners to send water into sanitary drainage system or trucked away.

Corrosion

Corrosion is another important dangerous matter among the salt water pool problems. Salty environment effects on the metallic equipments and attacks the cement in the plaster and floor materials. So if you installed a saltwater pool then the metallic objects are vulnerable and easily corrodes. Different metals such as nickel, galvanized steel, copper and titanium may able to develop a small electric charge. Moisture presence on the metal surfaces will rise to take place the corrosion processes. If the salt levels in the environment are low then the corrosion process is slow.

Chemical balance

Some pool owners think that salt water pools are not required maintenance. But they need water balance such as chlorine, pH, and alkalinity on a regular basis. On the other hand, occasionally they also need algaecide, clarifier, stain and scale control.

Chlorine Generator

Generator is used is salt water system for producing chlorine. After 1 to 3 years the cell of this generator should be replaced. The replacing cost is very high which is about $500 to $800. Moreover, calcium may deposit on the chlorinator cell; mainly for incorrect pH levels. It needs to be cleaning every 90 days. If it is goes long time without cleaning then the lifespan of the cell will be shortened. Low salt level in the pool can also harmful for the cell plate; reason it can responsible for oxygen production. It is better to keep the salinity levels between 2500 and 3500 to operate chlorine generator greatly. You should also know that single generator will not perfect for different salinity levels. Different chlorine generator would be perfect for different salinity levels.

Health salt water pool problems

Salt water swimming pool is harmful for health, because the skin will absorb sodium, salt, and chlorine. It is not suitable for the patients with high blood pressure, circulatory issues and a history of stroke.

Conclusion

Although the salt water swimming pool is easy to maintenance but it is not a great alternative of the traditional pools. If you are not able to take care properly, then it can corrode different parts including chlorine generator of your pools. So you should consider above salt water pool problems before installation.
