A Swimming Pool Water Treatment Plant (SWTP) is a highly specialized, automated infrastructure designed for the continuous and meticulous purification of water in commercial and public aquatic facilities. Its fundamental purpose is to uphold stringent public health standards by ensuring the water is pathogen-free, chemically balanced, and aesthetically clear.The process operates in a closed loop, starting with powerful circulation pumps drawing all pool water through surface skimmers and main drains. This water immediately undergoes physical treatment, first passing through a strainer to capture large debris, and then entering high-rate filtration units (often using layers of sand, activated carbon, or specialized glass media). These filters effectively remove suspended solids and fine particulate matter, significantly reducing turbidity.Next, the water receives chemical treatment. State-of-the-art dosing systems automatically inject a regulated amount of disinfectant (typically chlorine or bromine) to achieve and maintain a necessary residual level, thereby killing bacteria, viruses, and algae. Simultaneously, pH adjustment systems ensure the water’s pH is optimized (usually between 7.4 and 7.6), which maximizes the disinfectant’s efficacy and prevents swimmer discomfort and equipment corrosion. pH adjusting chemicals are added to ensure the disinfectant remains highly effective and the water is comfortable for swimmers. This continuous, multi-stage operation of the Swimming Pool Water Treatment Plant (SWTP) is crucial for regulatory compliance, prolonging the life of pool equipment, and guaranteeing a consistently clear and safe swimming environment for all users.
