What is the role of the water purifier before the three-level filtration? The water purifier generally uses a filtration method to remove harmful substances in the water. The method of hierarchical filtering is adopted. The following is the filter method currently used by the nuowei water opener:Level 1: pp cotton, effectively remove sediment, rust and small particlesLevel 2: granular activated carbon can effectively remove algae, chlorine gas, organic compounds and three-halogen methane.Level 3: compressed Activated carbon can effectively remove bacteria and spores make water cleaner and healthier.The third stage is the ultra-filtration membrane, which is more refined and can reach 0.001 microns. Drinking water is cleaner. The first grade pp cotton (five microns) filters sediment, rust, impurities and other second grade granular activated carbon to absorb chlorine in water. the third grade compressed activated carbon absorbs chlorine in water. some local raw water is slightly dirty or groundwater is used

What are the advantages of fiberglass filter material? Glass fiber has outstanding advantages such as high temperature resistance, corrosion resistance, stable size, high dust removal efficiency, and low price of dust stripping,Therefore, it is a kind of high temperature filtration material that is commonly used.1.1 Excellent heat resistance.The maximum operating temperature of glass fiber filter material treated by surface chemistry can reach 280 ℃,This is very suitable for the dust removal project.So in the present and in the future,Fiberglass is still an important material for high temperature filtration.2 high strength, small expansion rate.Its tensile strength is higher than that of other natural and synthetic fibers,The elongation is only 2%-3%,This feature is sufficient to ensure that the filter bag with a large aspect ratio made using its design has sufficient tensile strength and dimensional stability performance.Excellent corrosion resistance.At present, the common glass fib
