The main steps in circulating water treatment include pre-treatment, filtration, disinfection, and chemical treatment. First, during the pre-treatment stage, impurities such as suspended solids, oils, and particulates are removed through methods like sedimentation, clarification, or filtration. Then, filters further remove fine suspended matter and particles. Disinfection aims to eliminate bacteria and microorganisms, with common methods including chlorination, ultraviolet (UV) radiation, and ozone oxidation. Finally, chemical treatment is used to adjust the water's pH, control water hardness, and prevent corrosion and scale formation.
