Activated carbon filters to further the use of granular activated carbon filter to remove mechanical impurities residual chlorine in water, organic matter, suspended solids, providing good conditions for the subsequent Reverse Osmosis treatment.
Activated carbon filters mainly use high carbon content, molecular weight, high specific surface area of activated carbon for organic impurities in the water floc physical adsorption, the water quality requirements, when the flow of water through the pores of activated carbon, a variety of suspended particles, organic matter, such as the van der Waals force under the action of the pores of the activated carbon is adsorbed; While the surface of the activated carbon adsorption of chlorine (hypochlorous acid) chemical reaction in the carbon surface, is reduced to chloride ions, thereby effectively removing chlorine, chlorine content of less than 0.1 to ensure that the water ppm, to meet the operational condition of the RO membrane. Within the pores of the activated carbon over time between the particles and the retentate is gradually increased, the differential pressure across the filter is subsequently increased until failure. In general, according to the differential pressure across the filter, the filter backwash water using reverse, so that most of the pores of the activated carbon adsorption in the retentate stream and is peeled away to restore the adsorption function; When the adsorption capacity of activated carbon to achieve complete When the failure to deal with activated carbon regeneration or replacement of activated carbon to meet project requirements.
When activated carbon filters due to excessive mechanical impurities trapped affecting its normal work, the backwash method can be used for cleaning. Use of reverse water, so the filter filter layer loose, can adhere to the filter surface water retention recoil was peeled away, in favor of exclusion filter layer sediment, suspended solids and prevent media compaction, to make it fully restored interception, dechlorination ability to achieve the goal of cleaning. Backwash pressure drop parameters to control the backwash cycle, typically three to four days, depending on the specific subject of raw water turbidity may be.
Activated carbon filters can be manual or automatic control its start, flushing, backwashing, shut down other processes.
When activated carbon filter pressure drop is running to 0.05 ~ 0.07MPa, must be backwash. Activated carbon replacement period of six months to one year.
Activated carbon filter structure characteristics

Device body is put under a cylindrical steel oval head, the filter material is Q235-A or 304 stainless steel, corrosion vulcanized rubber lined inside with a cloth in water intake, a lower part of the catchment device catchment device the filling of 1200mm 200mm quartz sand and activated carbon. Body external device control equipment for a variety of valves and flow meters, pressure gauges.
