General ApplicationsCalcium hypochlorite is a widely used

chlorine compound that is highly effectiveagainst bacteria, algae, slime, fungi andother harmful and objectionable microor-ganisms. Since calcium hypochlorite as asolution is a very efficient killer of virtuallyall bacteria, algae and other objectionablemicro-organisms, it is used as a standard forcomparison testing of other sanitizing chem-icals.

While calcium hypochlorite is used pri-marily to chlorinate swimming pool, spa andhot tub water, and to treat water suppliesand sewage, it is also frequently used as ableaching agent and sanitizer in industrialapplications.

Calcium hypochlorite granules, tablets,or solutions can be used for continuouschlorination or applied manually.

Swimming Pool, Spa and Hot TubOperators use calcium hypochlorite as aroutine sanitizer to kill and prevent thegrowth of algae, bacteria, and othermicroorganisms. It is also widely used as ashock treatment to destroy organic contami-nation in pool water, thereby improving thewater clarity. Strong calcium hypochloritesolutions serve as disinfectants for cleaningpool sides and bottoms, decks, divingboards, ladders, floats, locker and showerroom floors and benches, sinks and toilets.

Municipal Water Treatment Municipalities use calcium hypochlorite inplace of chlorine gas or liquid bleach to

purify water. It is also effective for treatingwells; sanitizing new water mains; control-ling algae, especially sudden growths, inreservoirs, filters and other equipment;treating sewage and controlling odors.PPGs Induclor granular and -inch tabletedcalcium hypochlorite are NSF 60 certifiedfor drinking applications.

Wastewater Treatment Calciumhypochlorite is used to treat wastewatereffluents under controlled conditions bytextile mills, paper mills, tanneries, foodprocessing plants and more.

Other Applications Other uses forcalcium hypochlorite include sanitizing foodand beverage containers and productionequipment in dairies, restaurants, hospitalsand farms. Calcium hypochlorite also isused to control algae and slime in commer-cial and industrial cooling water systems.
