It mainly use activated carbon organic flocs with high carbon content, large molecular weight and large specific surface area to physically adsorb impurities in water to meet water quality requirements. When the water flows
through the pores of the activated carbon, various suspended particles, organic matter, etc. are adsorbed in the pores of the activated carbon under the action of van der Waals force; at the same time, the chlorine
(hypochlorous acid) adsorbed on the surface of the activated carbon undergoes a chemical reaction and becomes Chlorine ions, which effectively removes chlorine and ensures that the residual chlorine in the effluent
is less than 0.1ppm, which meets the operating conditions of the RO membrane. With the passage of time, the retentate in the pores of the activated carbon gradually increases, so that the pressure difference between
the front and rear of the filter increases until it fails.
