The filter cartridge is a very important part of the self-cleaning filter, and the correct selection of the cartridge is very important to play the role of the self-cleaning filter and ensure the normal operation of the water system.

Self-cleaning filter cartridge has several important technical parameters, one is the material of the cartridge, divided into 304 stainless steel, 316L stainless steel and special-purpose titanium, nickel alloy, etc.; second is the form of the cartridge, divided into drilling cartridge, wedge-shaped cartridge, woven cartridge and multi-layer composite cartridge; third is the filter precision of the cartridge, generally 25 microns - 3500 microns.

Now very many users in the choice of self-cleaning filter cartridge there is a big misunderstanding, think that the higher the filtering accuracy of the cartridge the better, it will be able to filter the impurities in the water are fast and clean. Filter cartridge selection actually has an important relationship with your equipment operating conditions, water flow, pressure, water quality requirements are the parameters to be considered when selecting the filter, some water systems have very low requirements for filtration accuracy, for example, the source water of the process water primary filtration, only need to filter out the leaves, large sediment, small fish in the water, such working conditions can choose a relatively low filtration accuracy (such as 1000-3000 microns) If you choose the filter cartridge with high filtration precision, although these impurities include some solid suspended matter smaller than these impurities filtered out, but there will be a series of problems such as excessive pressure loss of the water system, frequent start of the self-cleaning filter cleaning system, etc. The result is that the power consumption of the pump becomes larger, the cleaning water volume increases, and the production cost of the enterprise increases, which is different from the The use of self-cleaning filter is contrary to the original purpose.

Generally speaking, solid impurities that need to be filtered at 1000 microns and above, we suggest choosing a borehole type cartridge, impurities that need to be filtered within 100 to 1000 microns, choose a wedge-shaped cartridge or a woven cartridge, and if impurities below 100 microns need to be filtered, a multi-layer composite cartridge is a suitable choice. Of course, the situation of each system is different, some are to filter sediment-like granular solids in suspension, some are to filter more viscous impurities, some are to filter fiber-like impurities, for a variety of working conditions, you need to choose a different filtering accuracy.
