Performance analysis of Polyvinylidene Fluoride and Polyflux dialysis membranes

Artificial kidney (Dialyzer) is used for removal of wastes in case of renal failure. In India 17 percentage of people are being affected by end stage renal disease. So filtration of nitrogenous waste is carried out by the process of dialysis. In dialysis, reduction of accumulation of waste products, water and regulation of blood concentrations are performed by dialyzer (semipermeable membrane). The efficiency of dialysis is determined by the characteristics of semi permeable membrane. The ideal membrane should posses high permeability to water, organic metabolities, ions and should retain plasmaprotein. Dialysis membranes PVDF (Polyvinylidene Fluoride) and Polyflux are proven to be the superior in different aspects. In this work PVDF and Polyflux 6H will be compared and most appropriate of these two will be suggested. The comparision are implemented using finite element COMSOL Multiphysics 4.2a.
