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
Water is treated properly before feeding boiler. External Boiler Feed water treatment is the decrease or elimination of contaminants from water outside the boiler. It involves removal or reduction of some undesirable characteristics and addition of desirable characteristics to make water suitable and less troublesome for a proposed application before it is delivered to the point of use.

The function of the boiler is producing steam. The effectiveness of the boiler is depends on the water. Hence the boiler feed water quality is an important factor for boiler system. Lots of problems in the boiler system caused by water can be prevented in many cases if the water quality is controlled properly. Therefore, it is required boiler feed water treatment perfectly. In boiler, water Read more
Yamuna is the most polluted and important river in north India. It passes through Uttarakhand, Haryana, Delhi, and Uttar Pradesh, before join together with the Ganga at Allahabad in Uttar Pradesh. About 60 million people depend on Yamuna waters. The peoples of Delhi and Agra’s are one of the most consumers of the Yamuna River. This river is the source of 70 per cent of Delhi’s water Read more
Cooling water is used in any kind of industry and trouble in a cooling water system affects the operation of the whole production plant as well as the system itself. Therefore, the suitable quality of the cooling water must be controlled so that trouble free operation may be ensured.
Problems in cooling water system and their prevention
Problems commonly encountered with cooling water Read more
According to a report of PWA, the water crisis levels in all over the Gaza Strip have risen to an alarming stage; over 95 percent of the Palestinian territory’s aquifer is polluted with high levels of nitrates and chloride. Different tests show that pollutants in Gaza water are three times higher than the normal level. Moreover in most parts of the Gaza Strip, the pH level of water is below Read more
We know that water is the main component of beverages. If water is contaminant by some of elements then it may effects on the taste, odors and color of beverages.
Most treated water is chlorinated to destroy pathogenic bacteria and other micro-organisms. If the water contains little amount of free chlorine, even that are not identified by taste in water can react with others chemicals and may Read more
Water may be polluted in different ways. It effects enormous on aquatic life, environment and human beings. Some effects of water pollution are described below:
Effects of oxygen demanding wastes
The bacterial degradation of waste in water requires oxygen. In this process the bacteria consume the dissolve oxygen in water. If there are huge amount of oxygen demanding wastes, then the oxygen Read more
The major sources of water pollution are domestic wastes, industrial wastes, agricultural, and natural. The wastes are discharged into natural bodies and chemical pesticides and fertilizers, part of which are washed and go to the water bodies. They altered the water from the natural state in physical condition, chemical and microbiological composition.
The sources of water pollution are two Read more
The elements that causes of water pollution are referred as the water pollutants. Water pollutants may be classified under the following categories: organic, inorganic, radioactive and so on.
The following organic pollutants causes of water pollution.
Oxygen demanding waste: These types of wastes are different natural materials (as like plant leaves, grass), some artificial Read more
