OF WATER SUPPLIES WHY IS CHLORINE ADDED TO THE ATER Chlorine is used as a disinfectant that is to kill harmful microorganisms that may be present in the water supply and to prevent microorga. While not all microorganisms are harmful to human health there are some that may cause diseases in humans These are called pathogens Pathogens present in water can be transmitted through a drinking water distribution system causing wa terborne disea A ES AN D P AUL F LL ISINFE CT IN G YO LL W ER SHO CK C ORINA ION THE SHOCK CHL ORINA TION PROCESS A standard treatment for sanitizing your well system is shock chlorination Guidelines for using this treatment safely and effectively are listed below coli or fecal coliform For disinfecting wells to control iron or sulfur bacteria lease contact your Environmental Health Officer or Public Health Inspector BEFORE YOU START 1 Store sufficient water to meet family needs for 24 hours including the wat Chlorination Highsmith A, Espada A, Damiani E, Bean N, Abstract The cholera epidemic that began in Peru in January 1991 and swept through Latin America, causing more than 1.000,000 reported cases and 10.000 deat Chlorination requires FeCl3 !!Iodine must be oxidized to form a more powerful I+ species (with Cu+ or peroxide) 16.2 Other Aromatic introduces acyl group, "COR !!Benzene with acetyl chloride yields Propagation3.
