Problems solved by technology

[0002] As we all know, the filter pores of traditional multi-component filter elements are extremely fine and distributed in high density. Therefore, for areas with high water turbidity, it is very easy to be blocked by coarse particles such as sludge or rust, which will affect the filtered water volume. Therefore, one or more low-density filter elements with larger filter holes are usually installed in front of the high-density filter element, and the pre-filter element is used to remove coarse impurities, sludge, suspended matter, etc. in the water in advance, so as to protect the future Install high-density filter elements such as activated carbon filter elements, ion exchange resin filter elements, or semi-permeable membrane (R0) filter elements, so that they will not be covered by coarse impurities and affect their filtration or adsorption functions.
Its main defect is: the commonly used pre-filter element is nothing more than made of PP plastic, fiber, wool and other materials, so it must be discarded once it is blocked, and it cannot be washed again for reuse. Manpower and material resources are burdened, and because it does not meet the environmental protection conditions, it cannot be decomposed in a short time, so that it will become a highly polluting substance in the future, which does not meet the economic and environmental protection requirements
