A chlorine dosage of 2.7 mg/L is used to disinfect an average flow of 20 mgd. How many 100 lb chlorine cylinders are needed per month.
A single addition of chlorine yields a log kill every 5 minutes. During a storm, levels in the incoming water reach 100,000/mL. You hold the incoming water in a treatment tank and give it a single hit with chlorine. If you add the chemical at 8 a.m., when will it be safe to open the valve and release that water for drinking?

- Coming home after the end of the winter semester, you find that your family’s swimming pool has not be maintained well. In particular, it has no chlorine residual at all, and it is full of tree leaves. You buy a concentrated chlorine solution (1% as Cl2) and begin to meter it into the pool at a rate of 100 mL/hour. The pool has a volume of 200 m3. You also add new water, and remove in-pool water, at a rate of 3.785 L/minute. The chlorine reacts with the organic matter in the with a rate of 0.5/hour. How long will it take to get the Cl2 residual up to 1 mg/L if you add Cl2 continously.arrow_forwardThe Wood family and the Davis family each used their sprinklers last summer. The water output rate for the Wood family's sprinkler was 40L per hour. The water output rate for the Davis family's sprinkler was 30L per hour.

- The Flames Pool Company (FPC) was hired to drain a swimming pool when it is raining outside. If it is raining at a rate of 2 inches/hour and the flat swimming pool bottom surface area is 2000 ft2 answer the following two questions: What pump capacity in gallons/minute (gpm) must FPC use to keep the rain water accumulating in the swimming pool at a constant rate? What pump capacity in gpm must FPC use to reduce the rain water accumulation in the swimming pool at a rate of 4 inches/hour.arrow_forwardCan I get a thorough step by step for the following question? Each month the speedy dry-cleaning company buys 1 barrel (0.160 m3) of dry-cleaning fluid. The amount of the fluid lost to the atmosphere is about 232 kg/month and the remaining remains as residue to be disposed of. The density of the dry-cleaning fluid is 1.5940 g/mL.

- You are the Water Sanitation Engineer for Waterbury. Levels of bacterial cells in the water supply must be undetectable, which, in terms of the equation, is <1 per mL of drinking water. A single addition of chlorine yields a log kill every 5 minutes. During a storm, levels in the incoming water reach 10,000/mL. You hold the incoming water in a treatment tank and give it a single hit with chlorine. If you add the chemical at 10 a.m., when will it be safe to open the valve and release that water for drinking?
