Stainless Steel Cartridge Filter Housing for Reverse Osmosis Water Treatment Plant / System
Overview Precision filters (also known as security filters)
Security filter are mostly made of stainless steel and filter cartridges (such as PP cotton), which are mainly used after multi-media pretreatment filtration,
reverse osmosis, ultrafiltration and other membrane filtration equipment. It is used to filter out fine
substances (such as tiny quartz sand, activated carbon particles, etc.) filtered by the multi-media to
ensure the water filtration accuracy and protect the membrane filter elements from large particulate
matter. The precision of the filter element installed in the precision filter device can be divided into 0.5μs,
1μs, 5μs, 10μs, etc. Different filtration precisions are selected according to different use occasions to
ensure the accuracy of the post-water output and ensure the safety of the post-stage membrane
components.
PP cotton, nylon, meltblown and other materials are used as filter elements to remove tiny suspended
solids, bacteria and other impurities in the water, so that the raw water quality meets the water ingress
requirements of the reverse osmosis membrane.
Process principle
The security filter is a precision filter that works by mechanically filtering the pores of the 5 μm PP filter.
Traces of suspended particles, colloids, microorganisms, etc. remaining in the water are trapped or
adsorbed on the surface and pores of the filter element. As the water production time increases, the filter
element gradually rises due to the contamination of the retentate. When the water pressure difference
between the operation and the inlet and outlet reaches 0.1 MPa, the filter element should be replaced.
The main advantages of the security filter are high efficiency, low resistance and easy replacement.
