The Classification of Filter Cartridge

PP filter cartridge
PP filter element is also called PP melt-blown filter cartridge. The melt-blown filter cartridge is made of polypropylene superfine fibers entangled by hot melt. The fibers randomly form a three-dimensional micro-pore structure in space. The dimension pore size is gradient distribution along the flow direction of the filtrate. It integrates surface, deep layer and fine filtration, and can intercept impurities of different particle sizes. The accuracy of filter cartridge ranges from 0.5 to 100 um, and its flux is more than 1.5 times of that of peak room filter cartridge with the same accuracy. It can be equipped with different types of end cap joints to meet the needs of various engineering installation.
Wire-wound filter cartridge
It is refined from textile fiber yarn with good filtration performance by precisely winding on a porous skeleton. Its yarn materials are polypropylene fiber, acrylic fiber, degreased cotton fiber and so on. By controlling the tightness and density of the yarn during winding, filter cartridge of water purifiers with different precision can be made, which can effectively remove suspended solids and particulate impurities of various liquids, and has a high purification effect on various liquids.
Folding microporous filter cartridge
Folding microporous filter cartridge is made of polypropylene thermal spray fiber membrane and Nylon, PTFE microporous filter membrane. It has the advantages of small size, large filtration area, and high precision. Hot-melt bonding is used for sealing the end cap of filter cartridge and connecting the whole structure. The filter cartridge joints are three types commonly used in the world: 222 joints, 226 joints, and flat joints.
Filter cartridge Using RO Reverse Osmosis Membrane
NASA has spent billions of dollars on research for many years, with the support of the government, by bringing together scientists from many countries. The principle of reverse osmosis is to exert more pressure on one side of raw water than on the other side of natural osmosis pressure, so that water molecules can reverse osmosis from the high side to the low side. Because the pore size of reverse osmosis membranes is much smaller than that of case viruses and bacteria, viruses, bacteria, heavy metals, solid solubles, contaminated organic matter, calcium and magnesium ions cannot pass through reverse osmosis membranes at all, so as to achieve the purpose of water quality softening and purification.
