The filter element type liquid filter is a new type of multifunctional filter, which consists of two parts: the filter and the filter element. It has been widely used in water, oil, paint and other liquid purification and solid-liquid separation in chemical, metallurgy, chemical, textile, printing and dyeing, electroplating, medicine, food and other industries.
Filter element filters can be divided into the following types according to the commonly used filter elements:
PP filter element is also called PP melt blown filter element. The melt-blown filter element is made of polypropylene ultra-fine fiber thermally entangled. The fibers randomly form a three-dimensional microporous structure in space. The pore diameter is distributed in a gradient along the flow direction of the filtrate. It integrates surface, deep and fine filtration, and can intercept impurities of different particle sizes.
It is made by finely winding textile fiber yarn with good filtering performance on a porous skeleton. Its yarn materials include polypropylene fiber, acrylic fiber, absorbent cotton fiber, etc. By controlling the tightness and thickness of the yarn during winding, filter elements with different precision can be made, which can effectively remove suspended solids and particulate impurities in various liquids, and have a high purification effect on various liquids.
The pleated filter element is a precision filter device made of Polypropylene thermal spray fiber membrane, Nylon, PTFE microporous film. The membrane is folded into the filter element. It has the advantages of low pressure, long filter life, and high precision. Filter accuracy can range from 0.1μm to 30μm. The filter element end cover, sealing, and the overall structure connection are all hot-melt bonding. The filter element is glued with the center rod through the inner and outer three 226 joints, 222 joints, flat pressure, to ensure the sealing of the end cover and complete testing before leaving the factory to ensure the quality of the products.
There are two categories of activated carbon filter products: compressed activated carbon filter element, bulk activated carbon filter element.
A. The compressed activated carbon filter element uses coal-based activated carbon and coconut shell activated carbon with high adsorption value as the filter material. It is sintered and compressed with a food-grade adhesive. It can effectively remove organic matter, residual chlorine, and other radioactive substances in the water, and has the effect of decolorization and odor removal.
B. Bulk activated carbon filter element put the required activated carbon particles into a special plastic tank, and use welding equipment to weld the end cover on both ends of the shell. The two ends of the end cover are respectively put into the filter sleeves for filtering to ensure that the carbon core will not fall out due to carbon powder and back-washing use. According to the needs of customers, the filter element port can be made into different types of connection ports. Available interface types include flat press type, pipeline type (models: 4042, 4043, 4044), etc.

Resin is a polymer compound. There are many types of resins (also beads) in the resin filter element: anion resin, cation resin, mixed bed resin. The resin filter element is mainly used to soften water quality, remove calcium and magnesium ions in water, and reduce the hardness of water. The resin filter element can exchange the calcium and magnesium ions in the water with the sodium ions in the resin, which reduces the hardness of the water. When the resin exchanges calcium and magnesium ions to a certain degree of saturation, it needs to be regenerated, that is, the resin filter element is soaked in a saturated salt water solution, and the calcium and magnesium ions adsorbed on the resin are replaced, and the resin filter element is restored to the function of softening and exchanging ions. Finally, it can be reused. The resin filter element is mainly used in water purifiers and water softeners, and can also be used in pre-treatment equipment for reverse osmosis, and can be used for ion exchange for pre-treatment.
Filter element with RO reverse osmosis membrane: Reverse osmosis technology, the original text of reverse osmosis is REVERSE OSMOSIS, which is a membrane separation operation developed by the United States National Space Agency, with government support, after several decades, after years of research. The principle of reverse osmosis is to apply pressure on the side of the natural osmosis solution to reverse the water flow, and the raw water is sent to the higher concentration side to the lower concentration side. Since the pore size of the RO membrane surface is much smaller than that of viruses and bacteria, all kinds of salts, bacteria, heavy metals, solid soluble matter, colloidal organic matter, colloid and inorganic matter, etc., are all pass through the reverse osmosis membrane. So as to achieve the purpose of water softening and purification.
