As a High Precision Pleated Filter Element Exporter, share with you. First, determine whether to filter liquid or gas. According to the characteristics of the liquid or gas, filter membrane data or seal data is selected. Generally, hydrophilic membranes are used for filtering aqueous solutions, hydrophobic membranes can be used for filtering organic solvents, and hydrophobic membranes for filtering air.

The filtered flow 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 ton / hour (flux of filtered water). For example, to reach a flux of 1.0T, a 30-inch filter can be used, leaving some room for the appropriate amount. As the filtration stops, impurities accumulate on the surface of the filter membrane.

It will cause a drop in flux. If a 20-inch filter is used, the request may not be met. The pressure and temperature depend on the filtration temperature during filtration, the pressure above and below, and the disinfection conditions to determine the appropriate filter element. The working temperature of ordinary filter element is 80 ~ 90 ℃. Activated carbon fiber was 65 ° C, and stainless steel was folded to 200 ° C.

The sintered titanium filter element can reach 280 ° C, the pressure is 0.42Mpa / forward, the titanium sintered is 0.5Mpa, and the stainless steel folding filter element is 0.6Mpa. The filtering request reaches the level or accuracy (removal of bacteria and particles). The filtration efficiency of deep membrane filtration and membrane filtration is different. For example, the precision of sterilization is basically 0.2um; the relative accuracy of removing visible particles is 10-20um.

Filter manufacturers say that the life of filter elements will vary depending on the raw materials used. 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, which effectively controls the degree of pollution of the working medium.

According to the filter manufacturer, the filter of the filter element can be divided into coarse particles according to its filtering accuracy (particle size of impurities). delete). Filters are divided into four types: ordinary filters, precision filters and special filters, which can filter impurities larger than 100 μm, 10 to 100 μm, 5 to 10 μm, and 1 to 5 μm, respectively.

As the Pleated Filter Cartridge is used longer, impurities in the water will block the filter element, and the activated carbon filter element will absorb and saturate. Therefore, in general, the filter element needs to be replaced within 3 months, while the activated carbon filter element needs to be replaced within 6 months. Hollow fibers are usually placed in PP cotton because they cannot be cleaned.
