Operation problems of membrane distillation process - Fouling

Several application possibilities of membrane distillation which have the l argest chance for the industrial implementation have been presented. They i nclude ultrapure water production, the removal of metabolites from bioreact or, the concentration of acid and salt solutions and disposal of spent solu tions. The process problems occurring in these application have been discus sed, in particularly the fouling phenomenon associated with the deposit for mation on the membrane surface.
