Multi Cartridge Filter for High Flow Liquids with large Particles

Multi cartridge filter consist of a stainless steel filter housing and multiple filter cartridges like filter PP filter cartridge inside. It is mainly used after multi-medium pretreatment filtration and before membrane filtration equipment such as reverse osmosis and ultrafiltration to ensure the water filtration rating and protect membrane filter elements from large particles. In addition, single cartridge filters are also available to meet the demands of filtration applications requiring different flow rates and filter areas.

V-bands or swing-bolt closures are provided for quick filter cartridge replacement.
Suitable for accommodating filter cartridges with a length of 10", 20", 30" or 40".
Suitable for DOE and SOE filter cartridges.
Removable filter cartridges, easy to clean and replace.
Suitable for filtering fluids in high flow at various flow rates.
Other specifications are available upon request.

Working Principle

The unfiltered liquid flows into the filter from the inlet, flows through the cartridge from outside to inside and becomes clean. Impurities are trapped in the deep layer or on the surface of the cartridge and clean fluid flows out from the outlet.

When the differential pressure upstream and downstream is more than 0.2MPa and the flow rate of the liquid is 30% less than before, it is time to change the filter cartridge to prevent system clogging.
