The PL series security filter element is based on multi-layer composite filter materials, and through precise folding technology, maximizes the filtration area in a limited space and enhances the pollutant holding capacity. The filter material is made of high-quality polypropylene (PP) or glass fiber, which has the characteristics of high porosity and high retention rate.
It can effectively intercept suspended particles, colloids, microorganisms in water, and filter debris that may leak from the pre-treatment system.
The internal structure of the filter element adopts an integral skeleton structure with high mechanical strength, which can maintain stability and is not easily deformed even under harsh process conditions. The outer layer is equipped with a polypropylene mesh bag, which serves to fix the folded filter membrane and prevent the filter material from falling off. The filter element is sealed with O-rings at both ends to ensure reliable operation and no risk of leakage. In addition, the PL series filter cartridge also supports hot melt bonding technology to prevent particle release and unloading, further enhancing filtration safety.
The PL series security filter element plays an important role in multiple industrial fields due to its excellent filtration performance and wide applicability. In reverse osmosis water treatment systems, it serves as a terminal protection barrier, intercepting particles larger than 5 microns, reducing the risk of membrane fouling, extending membrane service life, and ensuring stable system operation.
In the pharmaceutical industry, PL series filters are used for filtering drugs, cell debris, biological products, etc., ensuring the purity of drugs and meeting GMP production requirements. In the electronics industry, this series of filter cartridges is used for high-purity water pre filtration and terminal filtration, removing ion exchange resin particles from water and meeting the high water quality standards required for semiconductor production. In addition, PL series filters are widely used in fields such as food and beverage, energy industry, chemical production, etc., providing reliable guarantee for various process water.
Compared to traditional filter element, PL series security filter cartridges have significant advantages. Its high flow design means that using fewer filters can meet system requirements, reducing labor and operating costs. At the same time, the small-sized filter housing design saves investment costs and floor space. The high dirt holding capacity and long lifespan of the filter element reduce the frequency of replacement, further reducing maintenance costs. In addition, the PL series filter adopts a modular design that supports online quick replacement, improving the flexibility and efficiency of system operation. Its excellent filtration performance and stability make this series of filter cartridges highly competitive in the market.
1. Frequent blockage of filter element
It may be caused by deterioration of inlet water quality, improper operation, or improper selection of filter element. The solutions include optimizing the upstream pretreatment process, controlling the flow rate of the filter reasonably, improving the backwash system, and selecting suitable filter material and accuracy.
2. Short lifespan of the filter element
This may be due to poor quality of the filter element itself or a small space for dirt collection. It is recommended to choose a filter element with reliable quality and large pollutant holding capacity, and regularly inspect and replace it.
3. Poor sealing
May cause water flow to bypass, affecting the filtration effect. During installation, it should be ensured that the filter element and filter are well sealed, and a sealing test should be conducted.
4. Rapid increase in pressure difference
It may be caused by filter blockage or system flow exceeding the design range. The clogged filter element should be replaced in a timely manner, and the system flow rate should be adjusted to the appropriate range.
