Overview of security filters Most of the precision filtration devices (also known as security filters) use stainless steel as shells, and the internal filter element (such as PP cotton) is mainly used after multi-media pretreatment and filtration, before membrane filtration equipment such as reverse osmosis and filtration. It is used to filter out small substances filtered by multiple media (such as tiny quartz sand, activated carbon particles, etc.) to ensure that water quality filtering accuracy and protective film filtering elements are not damaged by large particles. The precision grade of the filter element inside the precision filter device can be divided into 0.5 μs, 1 μs, 5 μs, 10 μs, etc., and different filtering accuracy is selected according to different use occasions, in order to ensure the accuracy of the rear effluent and ensure the safety of the rear membrane components. Using pp cotton, nylon, fusion spray and other different materials as filter elements to remove small suspended solids, bacte
