Precision security filter

1、 Overview of Precision Filters

Most security filters use stainless steel as the outer shell and are equipped with filter cartridges inside(for examplePPcotton)Mainly used after multi-media pretreatment filtration, before membrane filtration equipment such as reverse osmosis and ultrafiltration. Used to filter out fine substances after multi-media filtration(For example, tiny quartz sand, activated carbon particles, etc)To ensure the accuracy of water filtration and protect membrane filtration elements from damage caused by large particulate matter. The precision grade of the filter cartridge installed in the precision filtration device can be divided into0.5μs,1μs,5μs,10μsWait, choose different filtration accuracies according to different usage scenarios to ensure the accuracy of the effluent and the safety of the subsequent membrane components.

IIProcess Principle

Security filters belong to precision filters, and their working principle is to utilizePPfilter element5μmPerform mechanical filtration on the pores. Trace suspended particles, colloids, microorganisms, etc. remaining in water are intercepted or adsorbed on the surface and pores of the filter element. As the water production time increases, the operating resistance of the filter element gradually increases due to the pollution of intercepted substances. When it reaches the point where the water pressure difference between the inlet and outlet reaches0.1MPaAt this time, the filter element should be replaced. The main advantages of security filters are high efficiency, low resistance, and easy replacement.
