The role of various water purification filter elements. I. pp cotton filter element: 1> polypropylene fusion filter element is made of fiber with polypropylene resin as raw material, and is bonded by the winding of the fiber itself. The structure of the filter element is thick outer fiber, fine inner fiber, loose outer layer, and tight gradient diameter of the inner layer. The unique gradient deep filtration has formed the effect of stereo filter slag, which is characterized by high porosity, high interception rate, large amount of pollution, large flow and low pressure drop. 2> the pore size of PP melt blown filter element is dense and uniform, and the filtration efficiency is high. Because the particles will Bridge in the pores of the PP fusion filter element, the particles smaller than the pores can also be blocked, and the filtration efficiency is more than 98%. PP fusion filter element has high cleanliness and no pollution to water quality. Corrosion of chemical reagents such as acid and alkali and organ
