Mohr method is one of the significant methods for determination of chloride in water. It is also known as Argentometric method. Chloride ion is a negatively charged ion. This method is appropriate for neutral or slightly alkaline water. Water sample is titrating against standard AgNO3 solution by using potassium chromate indicator. It is a precipitation titration method.

The swimming pool pH level is one of the most significant factors in pool water balance. The pH is the determination of the acidity or alkalinity of the water. pH means hydrogen ions molar concentration in a solution. It is calculated by the formula –log[H+]. The pH level is measured from 0 to 14, whereas pH 7.0 is neutral. When the pH is below 7.0 then it is called acidic. Conversely, Read more
The total mineral that contains in the pool water such as calcium, magnesium, iron, manganese and sodium are responsible for Total hardness. On the other hand, 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 Read more
Chloramines in swimming pools are the effect of inadequate free chlorine. It is also called combined chlorine. Normally it produces strong odor of chlorine around the swimming pool and the pool water. Chloramine loses to a great extent of chlorine’s disinfect power. It is about 70 times less effective than free chorine. The maximum acceptable level of chloramines is less than 0.5 mg/l. Read more
Chlorine is a sanitizing chemical of water. It helps to keep pool water clean, as well as reducing and preventing algae growth and other unwanted water troubles. There are several types of pool chlorine such as gaseous, liquid chlorine, tablet chlorine, granular chlorine and powdered chlorine. You can discover here about the different types of pool chlorine to keep your pool water clean and Read more
During swimming pool maintenance, very often it is need to add chlorine. Sometimes the chlorine level becomes too much high. Therefore, it is need to lower swimming pool water chlorine level. Before, discussing “how to lower pool chlorine?” we discuss about why is chlorine used in pools water, how does chlorine work and dangers of chlorine.

The most common question from swimming pool owners are that “how to remove algae from pool water”. Reason, The development of algae is the general problem of them which is noticeable and looks ugly. They are single-celled organisms that grow quickly in the right conditions. Algae are microscopic size; hence they are invisible at naked eye, but visible when they accumulated. By keeping pool Read more
The contaminants are responsible for swimming pool water problems. Most of the problems are directly related to our health. Therefore, it is essential to testing and correcting the pool water regularly. Without testing you are not able to identify a particular problem accurately. The pool water maintenance is one of the biggest challenges for the pool owners or operators. Inadequate knowledge Read more

The possible affected date is from June 10 to June 18 of this year. The affected bands are Niagara Spring Water, Acadia Spring Water, Acme Spring Water, Big Y Spring Water, Nature’s Place Spring Water, Pricerite Spring Water, Read more
Even if external water treatment is designed and executed, it is inevitable that problems such as corrosion and scale still occur in the long run of the boiler operation. Boiler water treatment chemicals are therefore used for protecting a boiler plant from the problems and are applied for the whole systems including the feed water line and the steam condensate line. In case of internal boiler Read more
