Disinfectants Chloramines - Water Treatment and Purification

Chloramines remain in the water longer than chlorine. Monochloramines are most effective when the pH value is 7 or higher. When the pH value exceeds 7 the water is alkaline. The benefit of alkaline water is that it is less corrosive than acid water. When the pH value is high chlorine can be found in the water as hypochlorite ions (OCl-). These

It contains 70% available chlorine, 4-6% lime, and some calcium carbonate. Precipitates form when HTH is dissolved in hard water. For feeding calcium hypochlorite as a liquid, solutions should be prepared with soft water at 1-2% chlorine concentration. Care should be exercised in storing granular calcium hypochlorite.

The oxidizing characteristics that make chlorine and chloramine ideal disinfectants also cause them to react with organic matter in water and form disinfection byproducts (DBP). There are hundreds of reported DBPs, but less than a dozen are currently regulated by the U.S. Environmental Protection Agency, according to the Water Research Foundation.

The three most common chlorine-containing substances used in water treatment are chlorine gas, sodium hypochlorite, and calcium hypochlorite. The choice of the chlorine type to be used often depends on cost, on the available storage options and on the pH conditions required. Chlorination affects pH and pH affects results—a fact that is

Chlorine Chemicals used for Water Disinfection

Sodium hypochlorite is a yellowish liquid with an active chlorine concentration of 10-15% pH around 13.0. It is not very stable, and when it comes in contact with air, light or high temperatures, the chlorine evaporates and therefore its concentration in water decreases. The chemical reaction with water is: % Yield (of maximum) = 100 – b (ECe

Reduced chemical sludge volumes. Sludge density is increased. Improved results in higher pH systems. Better performance in cold water. And because PAC does function so differently, there are many applications where it will provide finished water quality that the traditional coagulants can't achieve.
