Activated carbon filters

Canister (quartz, activated carbon) material: steel tank Specifications: Φ2500mm (diameter) * 1500mm (effective height) Flow: 50T / H Total height: about 3350MM Working pressure: 0.6MPA maximum test pressure: 0.8MPA tank wall thick: 8MM Chenjiao: Chenjiao 3MM quartz sand amount: 9.7T pipe size: DN125 pipe material: carbon steel pipe structure: Flange elbow three links to the manual butterfly valve spray paint anti-corrosion warranty: one year working principle is to use a special filter sand filter will eliminate the tiny dirt in the pool. As remove dirt sand filtration media is loaded in the filter cavity. When the control knob "FILTER"; position, the water contains suspended particles of dirt from the pump into the filter pipe, and then by the guidance control switch reaches the filter outlet. Water passes through the filter, the tiny dirt is filtered out sand bed filtration. The filtered water from the bottom of the filter and then returned to the pool by a pipeline via the control switch. This set of procedures is continuously and automatically, and the pool filter and piping system provides a complete cycle. Filter through a period of use, the accumulation of dirt impede the flow diminished them. In this case it is necessary for filter cleaning. The control switch "; BACKWASH"; position, when the water flow in the opposite direction becomes, flow directly to the bottom of the filter chamber body cry, and then after kick up sand, previously trapped dirt, residue punch From outfall discharge, after each backwash, should control switch "RINSE"; position, the pump is turned off after 0.5 to 1 minutes, and then "FILTER" position, resume normal filtration. Quartz sand filter cartridge filter body with different sizes, from bottom to top by size compacted arrangement. When the water flowing down from the filter layer, the water contains suspended solids flowing into the upper layer filter tiny pores formed by adsorption and mechanical spoiler effect, suspended solids are trapped by the filter surface. At the same time, they are trapped between these suspended solids "overlapping" and "bridging" role in the filter layer formed on the surface film, continue to occur filtration. That is the effect of this so-called membrane filtration media surface. This film is not only the surface of the filter effect exists, and when the water flow into the intermediate filter layer also produce this interception. And different surface membrane filtration effect is that this intermediate interception called osmotic filtration. Associated with use: 1, before the filter to use a raw water pump, the water into the quartz sand filter. Flow rate less than or equal quartz sand filter traffic. 2, if too much water and suspended solids, colloidal material and more, can use a line mixer, the first suspension of colloidal substance is deposited in front of quartz sand filter, then filtered, the filter effect completely. 3, the line is equipped with a backwash function. In the backwash, should be equipped with a backwash pump (backwash pump can also share with the original pump a pump, just take a bend tee it), backwash flow rate less than or equal quartz sand filter traffic. 4, backwash frequency: according to the actual water conditions backwash time. 5, specific methods of operation, referring to instructions.
