Wedge wire self cleaning filter is a filter element constructed of high quality V-shaped wedge wires and support wires. It is installed in automatic self cleaning filter housings to intercept suspended solids and particles in the fluid, reduce turbidity and remove system impurities, thus purifying water quality and achieving self cleaning. It features high pressure resistance, corrosion resistance, uniform slot size, large filter area and not easy to clog, and is widely used in the automatic self cleaning filters in petroleum, paper & pulp, chemical, natural gas, food, and water treatment industries.
Wedge wire self cleaning filters are made of stainless steel, Hastelloy or other alloys. We can choose the right filter material to perfectly match up with your filtration environments.
The liquid enters the self cleaning filter and passes through the wedge wire screen inside to start the filtration process. Various dirt, particles in the liquid will build on gradually on the inner screen surface, and differential pressure gradually increases as well. When the differential pressure reaches the preset value, the control system will receive the signal, the self cleaning process begins. A part of filtered liquid (less than 1%) reenters the filter body, the motor drives the brush (scraper) to rotate to clean the screen and effectively remove the contaminants deposited on the screen surface. Meanwhile, the drain valve opens for discharging, the self cleaning process lasts about 12–18 seconds. During the entire self cleaning period, normal filtration part will be continuous with very low flow rate fluctuation.
