Ultrafiltration-Membranes
Supratec Membrane offers highest-quality ultrafiltration membranes based on PVDF at very competitive prices. Our membranes are characterized by an extremely porous and homogeneous pore structure. These excellent features lead to significant advantages in the operation of MBR applications:
- Significantly higher clean water permeability
- Consistently higher flux rates for MBR applications compared to other membranes available in the market.
- Reduced energy costs due to higher porosity and lower membrane resistance
- Lower investment costs due to a reduction of the required membrane area
- Strongly reduced membrane fouling due to smaller pore sizes and reduced pore blockage as well as associated longer service life of the membranes
- Enhanced cleaning efficiency and excellent cut off due to very narrow pore size distribution

Our membranes are impregnated with glycerin or other alternative material to prevent the membrane pores from collapsing during transport and storage. The conditioning material will be washed out before activation and final use. For the operation the membrane has to be activated.
For detailed instructions on washing, activating and conditioning or alternative activation procedures, please contact Supratec Membrane GmbH.
Applications
Municipal wastewater treatment
New sewage plant, water reuse plant, advanced retrofit and capacity expansion for conventional.
Industrial wastewater treatment
Diverse and variable influent quality is always a topic for industrial wastewater, so more robust and tolerance absorbed membrane like H series is a good opportunity to keep your plant safer. Well-known for its biodegradable difficulty and Harsh environment, H series membrane can still serve this application in a smooth way.
Drinking water treatment
New water treatment plant, enhancement of water quality, advanced retrofitting, and capacity expansion for conventional systems.
