Groundwater from a deep well is pumped at 400 gpm directly into the pipe network of a city. The well pump and pipe fittings are located in a well house. During the seasons of maximum usage, the pump operates for an average of 18 hr per day, with chlorine feed controlled by pump operation. The following chlorination systems are being considered to apply 0.50 mg/l of chlorine to the pump discharge: (a) liquid chlorine from a 100-lb pressurized cylinder through a solution feed chlorinator; (b) sodium hypochlorite solution with 10% available chlorine (by weight) fed from a 200-gal storage tank by a diaphragm pump; (c) powdered calcium hypochlorite with 70% available chlorine in a 50-gal tank and fed by a diaphragm pump. Calculate the quantity of chlorine applied per 18-hr day. Calculate the number of days each system can feed chlorine before requiring renewal. Which system would you recommend for a cold climate
