Is the PP meltblown filter element polluting water quality?

The PP meltblown filter element is made of food-grade polypropylene, and is produced by the internationally used tapered diameter process. It is made by heating, melting, drawing, and receiving. The fiber forms a three-dimensional microporous structure during the thermal bonding process. It has a gradient distribution from the inside to the outside, integrating the surface and deep coarse and fine filtration.

The outer layer is thick, the inner layer is thin, the outer layer is loose, and the inner layer has a gradually tapered structure. The unique gradient deep-layer filtration forms a three-dimensional filter residue effect, which has the characteristics of high porosity, high rejection rate, large dirt holding capacity, large flow rate, and low pressure drop. PP meltblown filter element has high cleanliness and no pollution to water quality. Resistant to acid, alkali and other chemical reagents and organic solvents.

PP meltblown filter element has high strength. When the pressure difference between the filter inlet and outlet is 0.4Mpa, the filter element will not deform. Filtration accuracy is divided into 1 micron and 5 micron. Primary filtration of raw water removes suspended matter, sediment, rust, colloids and other substances in the water to form RO membrane. PP meltblown filter element is made of textile fiber yarn with good filtering performance wound on a porous framework. By controlling the tightness and thinness of the yarn during winding, filter cores with different accuracy can be made. Can remove suspended solids and particulate impurities in water. PP melt-blown filter elements include polypropylene fiber, acrylic fiber, and absorbent cotton fiber.
