• Chlorine demand increases when organic matter increases• Fusible Plugs melt at 158 to 165 degrees• There are 6 fusible plugs on a two ton chlorine cylinder – 3 on each end• There are 3 fusible plugs on a 150 lbs chlorine cylinder• Gas chlorine – lowers Ph and strips Alkalinity• Gas chlorine increases hydrogen concentrations• Gas chlorine is non flammable• CL2 detectors are located at the lowest point where CL2 tanks are stored• Initial concentration of chlorine applied to new water mains for disenfection is50 mg/l• One volume of liquid chlorine confined in a chlorine cylinder under pressurewill yield about 460 volumes of gaseous chlorine.• Daily consumption of gas chlorine is checked by a platform scale• The permissible exposure limit (PEL) for chlorine is .5 ppm• The disinfection process is used to destroy or inactivate disease producing(pathogenic) organisms• Disinfection is the selective destruction or inactivation of pathogenicorganisms13
