WATER TREATMENT IN SWIMMING POOLS Swimming pools are individual projects , constructed in big schools , or in other community development projects. The quality of water required in swimming pool must be properly controlled, as to provide safe and pleasant bathing conditions in the pool. The water of pool should always be crystal clear, of good colour and attractive appearance. Essential Requirement of Swimming Pool Water and Its Surrounding 1. The water should be clear , of good clarity and attractive appearance. 2. It should be safe to bath in. 3. It should have approved quantities of disinfection dissolved in it. 4. It should have a comfortable temperature of about 27 to 30⁰ C. 5. The water of pool should be transparent , as to make the pool bottom clearly visible at maximum height. 6. The pool bottom , side walls and surroundings must be maintained clean and hygienic to a very high standard. Recycling of pool water: Reuse of water is accomplished by providing a filtration system, comprising of a pressure filter chlorinator and chemical dosing, and a pumping system to recirculate the entire pool water over a period of 4 to 16 hours. Water is some times aerated to eliminate dissolved gases, such as hydrogen sulphide , etc. aeration also gives a sparkling effect to the pool water. Pollution zones in a swimming pool 1. Surface Pollution may contain impurities and wastes like: a) Hair b) Dust c) Body grease, cosmetics d) Excreta from human nose and throat e) Floating debris f) Grass and leaves Method of removal: a) Removes surface water as soon as possible. b) Add sufficient chlorine to maintain free chlorine residual of 1-2 mg/L at all times. 2. Dissolved pollution may contain impurities like : a) Urine b) Perspiration c) Suntain lotion etc. Method of removal: a) Provide adequate filtration cycle b) Add sufficient chlorine to breakdown, nitrogenous matter and render it harmless. 3. Suspended pollution consists of a) Particles produced by chemical reactions in water treatment Method of removal: a) Use minimum quantity of chemicals b) Maintain balance water in pool c) Maintain careful control of pH and alkalinity d) Use chemicals which do not produce suspended solids 4. Deposited insoluble settling at the tank bottom may include solid wastes like: a) Dirt (soil , stones) b) Precipitated chemicals c) Sand from filters d) Fluff Method of removal : Adopt vacuum cleaning of the pool bottom daily. With an inefficient and inexperienced plant operator , serious problems can very quickly arise and cause discomfort to the bathers using the pools.
