Principle of use: Use coagulants (containing aluminum salts, iron salts, polymers, and other coagulants) and impurities in the water to form large-particle precipitates through flocculation and bridge action.

Advantages: Small particles of turbidity in water can be precipitated and then removed by suction filtration.

Disadvantages: Physical methods can only remove small particles of turbidity, and cannot effectively kill harmful microorganisms such as bacteria and fungi in pool water.

Cost: low cost

Suitable for the crowd: all kinds of swimming pools can be used

Pool Liner: No problem
