The precision filter is made of high-quality stainless steel 304 or 316L. Due to its light weight, easy operation, large filtration area, fast filtration speed, and no clogging, it is widely used in pre-treatment and filtration in various industries.
The precision filter can be equipped with filter cartridges of different models (from 10" to 40") and different types, such as PP melt-blown filter cartridges, Pleated filter cartridges, string-wound filter cartridges, activated carbon filter cartridges, etc.
Generally, the precision filter is installed before the pressure vessel to remove fine particles with turbidity above 1 NTU, thus meeting the water inlet requirements of subsequent processes. Occasionally, it is also installed at the end of the entire water treatment system to prevent fine particles from entering the product water. Most precision filters utilize stainless steel for the shell and are equipped with filter cartridges (such as PP cotton) inside. They are primarily used after multi-media pre-treatment filtration and before membrane filtration equipment, such as Reverse Osmosis (RO) and Ultrafiltration (UF). They are used to filter out fine substances (such as tiny quartz sand, activated carbon particles, and the like) remaining after multi-media filtration, ensuring the required water filtration precision and protecting the membrane filtration elements from damage by large particles. The precision level of the filter cartridges installed in the precision filtration device ranges from 0.5 μm to 100 μm. Different filtration precisions are selected according to specific application requirements to ensure the effluent precision and the safety of the subsequent membrane elements.

The shell of the precision filter is constructed from high-quality stainless steel, and the filter cartridge utilizes formed filter media, specifically polypropylene fiber melt-blown material. Under the action of pressure, the raw liquid passes through the filter media; the filter residue is retained on the media, and the filtrate flows out. It effectively removes impurities, sediments, suspended solids, and bacteria in the water, thereby achieving the intended purpose of filtration.
It can withstand relatively high filtration pressure and effectively remove suspended solids, rust, and so on in liquids.
The filter cartridge can be made of various materials to meet the needs of filtering various fluids.
Small volume, large filtration area, low resistance, and long service life;
Resistant to acids, alkalis, and other chemical solvents;
High filtration precision, uniform filter cartridge pore size, high strength, high temperature resistance, and the filter cartridge is not easily deformed.
Low filtration resistance, large flux, strong dirt-holding capacity, and long service life;
