Types of Filters 1:PP filter

PP filter is also called PP melt-blown filter.It’s one types of Melt-blown filter is made of hot-melt entangled polypropylene ultra-fine fibers. The fibers randomly form a three-dimensional microporous structure in space. The pore size is gradient distributed along the flow direction of the filtrate, focusing on the surface and deep layers. , fine filtration in one, which can intercept impurities of different particle sizes. The precision range of the filter element is 0.5-100μm, and its flux is more than 1.5 times that of the peak room filter of the same precision. Different types of end cap joints can be configured to meet the needs of various engineering installations.

Types of Filters 2:Wire-wound filte

It is made of textile fiber yarns with good filtration performance precisely wound on a porous skeleton. Its yarn materials include polypropylene fiber, acrylic fiber, absorbent cotton fiber, etc. By controlling the winding tightness and density of the yarn during winding, water purifier filters with different precisions can be made, which can effectively remove suspended solids, particulate impurities, etc. from various liquids, and have a high purification effect on various liquids pleated filter .

Types of Filters 3:Foldable microporous filter

The pleated microporous filter is a precision filter device made of polypropylene thermal spray fiber membrane, nylon polytetrafluoroethylene (PTEE) microporous filter membrane and other filter media. It has the advantages of small size, large filtering area and high precision. Filtration accuracy ranges from 0.1μm to 60μm. The filter element end cover seal and overall structural connection are all made of hot melt bonding. There are three types of filter connectors commonly used internationally: 222 connector, 226 connector, and flat mouth. Products undergo rigorous and complete testing before leaving the factory to ensure stable product performance.

Types of Filters 4:Activated carbon filter

There are two major categories of activated carbon filter products: compressed activated carbon filters and bulk activated carbon filters.

1. The compressed activated carbon filter employs coal-based activated carbon and coconut shell activated carbon with high adsorption value as filtering materials, sintered and compressed with a food-grade binder. It wraps the compressed activated carbon filter element inside and outside with a layer of non-woven fabric, providing a filtering effect to prevent the carbon core from releasing carbon powder.Equipping soft nitrile rubber sealing pads at both ends of the carbon core facilitates the loading of the carbon core into the filter cartridge and ensures good sealing properties.

2. Bulk activated carbon filter element: Put the required activated carbon particles into a special plastic shell, use welding equipment to weld the end caps to both ends of the shell, and put non-woven fabrics for filtering into both ends of the shell. Filter to ensure that the carbon core will not drop carbon powder and black water during use. Customers can customize the shell end cover to have various types of connection ports based on their specific needs.The interface methods include: flat pressure type and pipeline type.

Types of Filters 5:Double section filter

Activated carbon indicators: strength>90; iodine value (mg/g)>950; methylene blue value (mg/g)>120.

Types of Filters 6:Ceramic filter

The ceramic filter element, composed of pure natural physical materials, avoids generating secondary pollution during the water purifier’s use.At the same time, unlike the ceramic filter element of the pure water machine, it can remove all kinds of minerals. It retains beneficial minerals in the water while effectively removing mud, sand, bacteria, and rust.It remains unclogged, boasts a long service life, and delivers excellent filtration effects.At the same time, it is not afraid of clogging and can adapt to very poor water quality conditions. At present, the ceramic filter element with the highest filtration accuracy in the world is a dual-control membrane ceramic filter element with an average pore size of 0.1 μm. The water filtered by this filter element does not need to be boiled and can be drunk.

Types of Filters 7:Resin filter

Resin is a porous, insoluble exchange material. In the water softener, the resin filter element comprises millions of tiny plastic balls (beads), each hosting numerous negative charge exchange sites that attract positive ions.

In the resin’s initial state, positively charged sodium ions occupy these charge exchange sites. When calcium and magnesium pass through the resin tank, they contact the resin beads, displacing the sodium ions from their exchange positions.

The resin preferentially binds strongly charged cations, calcium and magnesium ions having a stronger charge than sodium ions. The displacing sodium cation then flows down through the resin “bed” and out of the softener, which delivers “soft” water. Eventually, all resin exchange positions are occupied by calcium and magnesium and can no longer function.

Types of Filters 8:Titanium rod filter

The titanium rod filter element exhibits outstanding characteristics, including corrosion resistance, high-temperature resilience, high strength, easy maintenance of filtration accuracy, and straightforward regeneration. Formed from titanium powder and sintered at high temperatures, the filter’s surface particles remain firmly in place. With a use temperature in the air reaching 500~600℃, it is suitable for filtering various corrosive media, including hydrochloric acid, sulfuric acid, hydroxide, seawater, aqua regia, and chloride solutions like iron, copper, and sodium. Its excellent mechanical properties allow for processing through cutting, welding, and other machining methods.

It has high pressure resistance and internal pressure destruction strength of up to 2MPa. Its filtration accuracy is easy to ensure, and the pore diameter will not deform even if it works under high temperature and high pressure.With a porosity ranging from 35-45%, a uniform pore size distribution, and a substantial dirt-holding capacity. The titanium rod filter element boasts a simple regeneration method, allowing for reuse after regeneration.

Types of Filters 9:RO reverse osmosis filter element

Filter element using RO reverse osmosis membrane. Reverse osmosis technology: The original text of reverse osmosis is REVERSE OSMOSIS. NASA spearheaded the development, bringing together scientists from various countries and investing billions of dollars with government support after years of extensive research.The principle of reverse osmosis is to exert a pressure greater than the natural osmosis pressure on the raw water side, so that water molecules can reverse osmosis from the side with higher concentration to the side with lower concentration. Since the pore size of the reverse osmosis membrane is far smaller than hundreds or even thousands of times of viruses and bacteria, various viruses, bacteria, heavy metals, solid soluble matter, polluted organic matter, calcium and magnesium ions, etc. cannot pass through the reverse osmosis membrane at all. , thereby achieving the purpose of water softening and purification.
