Human fluids such as perspiration,
surface skin/dirt contamination, urine and fecal matter are the major health concerns for aquatic centers and public pools. Outdoor pools face a different challenge, as well as filtering human fluids they can be contaminated with animal droppings, algae, debris (leaves) and rain. Aquatic centers undergo a number of filtration processes in order to keep its water clean. Below you will find a list of common water filtration methods;
Physical Methods: Screens, regenerative media filtration and high efficiency submicron media filtration.
Membrane Methods: Microfiltration, ultrafiltration, nanofiltration and reverse osmosis.
Chemical Methods: Chemical additions, clarification, deionisation and softening
Disinfection Methods: Chlorine disinfection, ozone disinfection and UV
Biological Methods: Anaerobic or aerobic bacteria.
