Meishan backwash filter made of high quality carbon steel cylinder main straight, stainless steel mesh, the special structure of the sewage plant components. When the filter work, flow from the inlet into the filter, through the mesh filter, filter impurities in the water is trapped, clean water sent through the outlet (see Figure 1). When the filter out of the water pressure reaches between 0.06-1.0MPa (or water pressure is too low, can not meet the normal operation of the rear system), you will need to filter backwash. Close the flow direction valve, water flows through the inside of the filter backwash filter impurities trapped by the outfall discharge, played the role of reverse automatic flushing filter "Xiao Jia released" ◆ structure: YD-type filter backwash Meishan from the shell, stainless steel filter cartridge, impurities collect segment, electric impurities outfall, electric water valve turned, testing organizations, actuators and control box. By installation type and flow direction divided into two kinds of straight-angle formula. Meishan backwash filter characteristics and technological innovation a functional obvious: easy operation and management, filtration, high speed, simple and reliable flushing, backwash ability, no power, energy saving. 2, reliable: the filter can work at full flow, while maintaining a high flow, but also has a low pressure drop (less than 0.05-0.1m water column), to avoid surface stains caused due to low flow rate. 3. Installation is simple: mounted directly on the pipe network system, without any supporting structure, can be installed vertically and horizontally, the same effect. 4, easy to operate: just manually rotating the valve handle to open the drain valve, discharge time is only a few minutes, a small amount of work, low labor intensity. 5, energy investment operating costs: During the installation process without high bypass management, reduced investment and installation costs three bypass valve, mounted directly on the pipe-line, without any supporting structure, save space. Without dismantling the sewage, reduce labor intensity, to avoid the process of debugging and maintenance disassembly and sewage, labor, effort, time-saving.
