Chlorine compounds which are used for disinfecting water systems are chlorinated lime, high-test hypochlorite (H.T.H., Perchloron, Pittchlor, or equivalent), or commercially prepared liquid sodium hypochlorite (Chlorox, Zonite, or equivalent). Chloride of lime and liquid sodium hypochlorite can be purchased at almost any grocery or drug store. As these compounds deteriorate on exposure to air, they should be purchased in small containers and the tops of the cans or bottles tightly replaced after use. All products should be kept in a cool, dark place. The instructions that follow should be utilized in the disinfection of potable water systems by the use of chlorine con-: pounds: (1) Thoroughly scrub the storage tanks and flush thetanks and dis- tribution system with potable water. (2) Determine the volume of water necessary to completely fill the tanks and distribution system. The amount of disinfecting agent that will be required may be secured from Table II. When chlorine compounds or solutions other than those noted in the table are used, the dosage should be: 70% DSSS Wop dikh ales. 730 = Sa SN a 2 Sn % chlorine in compound dl x dosage in 70% column Dosage of liquid = 2 dosage in 5% column % chlorine in liquid
