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.
