Activated Carbon Filter
Product Description
The main body of the equipment is a cylindrical steel structure with upper and lower elliptical heads. The filter material is Q235-A or 304 stainless steel, and the inner lining is vulcanized rubber for anti-corrosion. There is a water distributor at the water inlet, and a water collecting device and a water collecting device at the lower part. Filled with 1200mm of activated carbon and 200mm of quartz sand. The activated carbon filled in the activated carbon filter is nut shell carbon, which has the advantages of light specific gravity, large porosity, strong wear resistance and large adsorption capacity.
Working Principle
The activated carbon filter mainly uses activated carbon organic flocs with high carbon content, large molecular weight and large specific surface area to physically adsorb impurities in the water to meet the water quality requirements.
When the water flows through the pores of the activated carbon, various suspended particles, organic matter, etc. At the same time, the chlorine (hypochlorous acid) adsorbed on the surface of the activated carbon undergoes a chemical reaction on the surface of the activated carbon and is reduced to chloride ions, thereby effectively removing the chlorine and ensuring that the residual chlorine in the effluent is less than 0.1 ppm, which meets the operating conditions of the RO membrane.
With the passage of time, the retentate in the pores of the activated carbon and between the particles gradually increases, so that the pressure difference between the front and rear of the filter increases until it fails. Under normal circumstances, according to the pressure difference between the front and rear of the filter, reverse water flow is used to backwash the filter material, so that most of the retentate adsorbed in the pores of the activated carbon is stripped and taken away by the water flow, and the adsorption function is restored; when the activated carbon reaches the saturated adsorption capacity completely When it fails, the activated carbon should be regenerated or replaced to meet the engineering requirements
APPLICATIONS
The filter has a reasonable structure and is easy to use, and is suitable for various restaurants, hotels,troops, stations, docks, industrial and mining enterprises and institutions with high water quality requirements, as a deep purification equipment for domestic application water. The equipment is used in coniunction with the ultraviolet drinking water sterilizer, and can be used as an ideal water purification equipment for industrial water such as brewing beverages, food, pharmaceuticals, and chemicals. At the same time, it can also be used as post-processing equipment for industrial sewage.
