Internal Pressure Type

Precise separation performance
The coordinated design of nano-scale pores and pore density enables the Internal pressure-type ultrafiltration membrane to have a 98% interception rate for substances with a molecular weight greater than 10 kDa. The internal pressure driving mechanism reduces the concentration polarization effect. Compared with the external pressure membrane, its flux attenuation rate is reduced by 35%, and the yield is increased by 20% in applications such as juice concentration.

Wide temperature range material adaptability
Using a high-temperature resistant polymer or alloy substrate, the internal pressure type ultrafiltration membrane can operate stably in the range of -40℃ to 600℃. At low temperatures (-20℃), the elastic modulus of the material only decreases by 12%, ensuring sealing; the flux attenuation rate is less than 8% during continuous operation at high temperatures (40℃), which meets the needs of high-temperature wastewater treatment.

High maintenance efficiency
The internal pressure type ultrafiltration membrane with open flow channel design increases the media coverage by 40% by optimizing the cleaning path and reduces the use of chemical cleaning agents by 30% with the backwash device. Its modular components support quick replacement in 5 minutes, which shortens the maintenance time by 70% compared with traditional welded equipment.

 Stability in a high-pressure environment
The structural strength of the internal pressure-type ultrafiltration membrane is optimized through finite element analysis. The deformation is strictly controlled within 0.1% within the working pressure difference range of 0.1-1.0 MPa, ensuring that high-efficiency separation capacity is maintained under high-pressure impact. Under continuous loading of 1.0 MPa, the membrane pore size change rate is less than 2%, and the interception efficiency is stable at more than 98%, which fully meets the needs of high-pressure application scenarios such as industrial wastewater treatment.
