Pollution in pool water comes either from the environment or is carried into the water by the swimmers. Environmental pollution includes dust, leaves, chemical wastes, pollen, spores, bacteria and so on, that are blown into the water by the wind. Swimmers carry other pollutants into the water: sweat, suntan oils, urine, bacteria, viruses, etc.
Every swimming pool has a circulation pump and filter. The filters most common these days are:
Sand Filters (the most common type)
The pool pump ensures that the swimming pool water moves through the filter every day, thus removing unwanted pollutants and disinfected organic materials as quickly as possible.Generally, the swimming pool pump should run for at least 6 - 8 hours each day.
