What is the difference between PP Pleated Filter Cartridges, PTFE Pleated Filter Cartridges and PES Pleated Filter Cartridges?

PP Pleated Filter Cartridges is a relatively accurate, pre-filter material (very cheap), which can only intercept larger colloids and particles. Filtering acts as a protection. However, it has strong adsorption performance and a large amount of dirt, which cannot be achieved by PES and PTFE. (As a relatively accurate material, its aperture size is generally of little significance and does not need to be entangled.

PTFE Pleated Filter Cartridges can be generally divided into hydrophilic PTFE and hydrophobic PTFE, hydrophilic filtered liquid, and hydrophobic filtered gas. According to the casting process, they can be divided into casting membranes and continuous casting molds. Due to the unique four F atoms surrounding carbon structure of PTFE, this material has strong chemical stability, strong acid resistance, strong alkali resistance and organic solvent resistance. As the material itself is hydrophobic, the hydrophilic PTFE is treated, so the liquid flux of the hydrophilic PTFE membrane is relatively poor. Finally, PTFE is an absolute precision filter that can be used with terminal liquid sterilization, and gas sterilization

PES Pleated Filter Cartridges are the most commonly used material for terminal sterilization filter cartridges. It has good hydrophilicity and low protein adsorption, which brings it the characteristics of high flow rate and long life. Filters with the same precision are generally 200 mbar ( Under the pressure of 0.2 kg), the liquid flux per unit length and unit time can reach 2 times that of PTFE. The precision of the sterilization grade filter element is generally 0.22μm and 0.45μm.

When do PP Pleated Filter Cartridges need to be replaced?

When these flocculants are added in a small amount, the excess flocculants will self-aggregate among themselves to form large particles, which can be trapped by the filtration process. Inner fouling of the membrane surface due to entrapment. The filter belongs to precision filtration, and its working principle is to use the pores of PP Pleated Filter Cartridges5pm for mechanical filtration.

Trace suspended particles, colloids, microorganisms, etc. remaining in the water are trapped or adsorbed on the surface and voids of the filter element. With the increase of water production time, the running resistance of PP Pleated Filter Cartridges increases gradually due to the pollution of retentate. When the pressure difference between inlet and outlet reaches 0.15MPa, the filter element should be replaced.
