Disinfection of well water ...

Disinfection of well water is rather tricky as amount of water is unknown, thus quantity of disinfectant cannot be decided properly. Although chlorine is the most suitable disinfectant for controlling cholera we have to depend on the chlorine releasing agents like bleaching powder / calcium hypochlorite / chlorine dioxide / sodium hypochlorite etc.; all these agents releases chlorine immediately and thus there is momentary rise in free chlorine level. This peak level slowly subsides to lowest level (even nil / zero) depending on chlorine demand of water. Since chlorine demand is not known plus water quantity is not known, treatment becomes blind. 

What one need is controlled release of chlorine to maintain at leat 0.5 ppm free radical chlorine for prolong time, preferably all the time. Such maintenance of chlorine in continuous operation is made possible by using product CHLORITARD developed by us. It is used for maintaining chlorine continuously for period of 1 month in overhead water tank consumed and filled daily (once or twice). It has to be replaced every month by choosing pouches of various capacity ranging from 500 lit water used per day to 50000 lit water used per day. For higher capacity water use, multiples of pouches can be used. This do not require electricity or any technical support, thus illiterate or village people can use it comfortably.
