PERVAP™ 4155-30, 4155-40, 4155-50, 4155-60, 4155-70, 4155-80

DeltaMem’s PERVAP™ 4155-xx is series of membranes with different cross linking, suitable for removal of methanol and/or water from volatile organic mixtures. By changing the cross linking of the membranes it is possible achieve an optimal balance between selectivity and flux that optimizes separation efficiency for a given product quality.

This membranes series comprises six membranes with increasing cross-linking degreed.
