Pool water pollution Section 3 Section 3: Pool water pollution It is important that the pool operator understands the causes of pool water pollution and contamination, and the role that the plant plays in dealing with or removing them. The causes of pool water pollution can be separated into three categories: • Physical pollutants • Chemical pollutants • Biological pollutants The common denominator for all these forms of pollution is the bathers themselves. Pollution added by bathers Bathers introduce all three types of pollution to the pool water: physical, chemical and biological. Each day, an adult produces 1 litre of sweat, 1 billion skin fl akes and 38g of grease (SPW). It is also estimated that each bather releases approximately 30ml of urine and 200mg of urea in a typical swim session. When a bather is exercising, they also release a signifi cant amount of sweat; this increases in line with pool water temperature. In addition, the human body carries numerous chemicals in the form of cosmetics, deodorants, powders, creams, lotions, oils, etc, all of which add further pollution to the water. Outdoor pools Outdoor pools, especially those found in warm climates, experience signifi cant problems caused by suntan lotion and sweat added by the bathers, as well as environmental pollution from sand, leaves, grass, soil, etc. Types of pollution The types of pollution can be further classifi ed as: • Surface pollution • Dissolved pollution • Suspended pollution • Insoluble pollution They can be found in various places in the pool itself (as illustrated in fi gure 3.1).
