WATER VAPOR PERMEABILITY AND FOULING IN WATER REMOVAL FROM BLOOD BY MEMBRANE DISTILLATION

Abstract

Techniques of membrane distillation have been developed in the fieled of desalination and alcohol concentration. In this work, solute-free water was removed from bovine plasma, bovine blood and discarded dialysate with the use of polytetrafluoroethylene (PTFE) and polyvinylidene-fluoride (PVDF) membranes. Both membrane structure and temperature polarization layer affect permeate flux in membrane distillation.
