Ultrafiltration – Flat Sheet Membrane

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

Chemical Tolerances

	Max cleaning concentration	Max operating concentration	Life time exposure
Chlorine as Cl at 20°C	5,000 ppm	6 ppm	5,000,000 ppm·h
Chlorine as Cl at 40°C	3,000 ppm	4 ppm	3,000,000 ppm·h
Acid/Base at up to 40°C	2 – 11 pH	5 – 10 pH	70,000 ppm·h as NaOH
Mixture of base and Cl2	3,000 ppm Chlorine	n.a.	3,000,000 ppm·h Chlorine
Ozone at 40°C	0.5 ppm for < 300 h	0.50 ppm	200 ppm·h
Ozone at 20°C	0.55 ppm for < 300 h	0.55 ppm	250 ppm·h
Water oversaturated O2	n.a.	Oversaturated	No limit

Conditioning/drying prevention:

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.
