What is Cartridge Filter? What are the advantages?
The cartridge filter can remove suspended solids (sand/rust, etc.), colloids (mainly substances with smaller particle size), and some organic matter (which can remove part of the color/odor to improve the water quality).
Main technical specifications:
- Filter precision: 0.01-100 microns
- Temperature resistance: 80 °C
- Maximum working pressure : 150 psi
- Treatment capacity: 1-50000 m3/h
- Finish: Polished or sandblast external surface
- Cartridge length and quantity: can be customized
Advantages:
- Good resistance effect of corrosion, heat, pressure and abrasion.
- The stainless steel cartridge has accurate filtration precision.
- Large treatment capacity and long service life.
- The filter element has no pollution to the filter medium.
- The stainless steel cartridge can be reused after cleaning.
Typical cartridges:
PP meltblown cartridge
It is made of food-grade polypropylene and produced by the general gradual diameter process, which is heated and melted, sprayed, traction and received into shape, and the fibers form a three-dimensional microporous structure during the thermal bonding process, and the microporous pore size is distributed in a gradient from inside to outside, integrating surface and deep coarse and fine filtration.
The outer layer of fibers is coarse, the inner layer of fibers is fine, the outer layer is loose, and the inner layer is tight structure. PP meltblown cartridge has the characteristics of high porosity, high retention rate, large dirt-holding capacity, large flow rate and low pressure drop, and has high self-cleanliness and no pollution to water. PP meltblown cartridge has high strength, and the cartridge will not be deformed when the pressure difference between the filtering inlet and outlet is 0.4Mpa.
The filtration precision is divided into 1 micron and 5 micron. The primary filtration of raw water removes suspended matter, sediment, rust, colloid and other substances in the water, forming RO membrane inlet requirements water.
Folded cartridge
It adopts polypropylene thermal spray fiber membrane, nylon, PTFE microporous filter membrane, etc. as the filter media to make the precision filter parts.
The end cap seal and the overall structure connection of the cartridge are all bonded by hot melt, which has the advantages of small volume, large filtration area and high precision.
The filtration precision ranges from 0.1 micron to 60 micron. It can remove visible particles and suspended matter in water.
Stainless steel screen cartridge
High strength, good rigidity, uniform precision, and can be used repeatedly.
The filtration precision is from 30 to 80 microns, capable of removing visible particles, suspended matter, etc. from water.
