First make it clear whether to filter liquid or gas. According to the
characteristics of the liquid or gas, the filter material or sealing material are
selected. The hydrophilic membrane used for filtering aqueous solutions is
generally used, the hydrophobic membrane used for filtering organic solvents can
be selected, and the hydrophobic membrane used for filtering the air.
The flow rate of filtration is based on the flux provided by the consumer process to consider the size of the filter and the number of filter elements. Generally speaking, the flow rate of the filter element (10 inches) is 0.5 tons / hour (the flux of filtered water), for example, to reach a flux of 1.0T. A 30-inch filter can be selected, leaving a reasonable amount of room, because the As the filtration stops, impurities accumulate on the surface of the filter membrane.

Will cause flux to fall. If a 20-inch filter is used, it may not meet the requirements. The pressure and temperature will be determined according to the filtering temperature up and down, the pressure up and down, and the sterilization conditions. The working temperature of common filter element is 80 ~ 90 ℃. Activated carbon fiber is 65 ℃, stainless steel folded to 200 ℃.
Titanium sintered filter element can reach 280 ℃, the pressure is 0.42Mpa / positive, titanium sintered filter element is 0.5Mpa, stainless steel folded filter element is 0.6Mpa. The filtration request reaches the level of precision of the filtration requirement (sterilization, particle removal request) For deep membrane filtration and membrane filtration, the filtration efficiency of the two is different, for example, the sterilization basically selects the accuracy of 0.2um; the removal of visible particles can choose the relative accuracy of 10-20um.
According to Water Treatment Cartridge Filter Supplier, according to the raw materials used, the service life of the filter element will be different. The filter element is the core component inside the filter. In the hydraulic system, the filter element is used to filter out solid particles and gel-like substances in the working medium, effectively controlling the pollution degree of the working medium.
Pleated Filter Cartridge can be classified into coarse particles based on their filtration accuracy (particle size of impurities). delete). The filter is divided into four types: ordinary filter, precision filter and special filter, which can filter impurities larger than 100μm, 10 to 100μm, 5 to 10μm and 1 to 5μm.
