Most of the high-throughput security filters use stainless steel as the shell, and filter elements (such as PP cotton) are installed inside. They are mainly used after multi-media pretreatment filtration and before reverse osmosis, ultrafiltration and other membrane filtration equipment. It is used to filter out fine substances filtered by multimedia (such as tiny quartz sand, activated carbon particles, etc.), so as to ensure the accuracy of water quality filtration and protect the membrane filter element from being damaged by large particles. The precision level of the filter element installed in this filter can be divided into 0.5μs, 1μs, 5μs, 10μs, etc., and different filtration precisions are selected according to different usage occasions to ensure the accuracy of the final water outlet and the safety of the subsequent membrane elements. Using different materials such as PP cotton, nylon, meltblown and other materials as filter elements to remove tiny suspended solids, bacteria and other impurities in the water, so that the raw water quality can meet the water inlet requirements of the reverse osmosis membrane..

Large flux security filter structure:

The security filter is a filter that uses the filter element as the filter medium to separate liquid and solid by pressure. The method of liquid-solid separation using a filter element belongs to the microporous filtration technology. It is mainly suitable for materials with solid particles of 0.5-10 μm or larger than 0.5 μm, but the particles are non-rigid and easy to deform, and the viscosity between particles or between particles and the filter medium is relatively large. Difficult-to-filter materials. The liquid to be filtered is pressed into the filter inlet, and the filter element penetrates the filter layer from the outside to the inside to be filtered into a clear liquid, and then discharged through the filter. Impurities are trapped in the deep layer and surface of the filter element, so as to achieve the purpose of filtering liquid, but the filter element should not be used for too long, because the filter element is easy to breed bacteria.
