REMOVAL OF HAZARDOUS SUBSTANCES FROM WATER USING ULTRAFILTRATION IN CONJUNCTION WITH SOLUBLE POLYMERS

The applications of separation techniques using ultrafiltration in con nection with functional soluble polymers for the removal of environmen tally relevant and toxic substances from waters are reviewed. The type s of interactions of the soluble polymers with low molecular mass comp ounds, the criteria for selecting the appropriate polymeric agents, an d the binding conditions are discussed. Several factors influencing th e separation of the target substances such as membrane type, solution composition, synergism, polymer adsorption, deformation of macromolecu les, and hydrodynamics are evaluated and highlighted. Chemical, electr ochemical, and thermal regeneration aspects are also covered. Finally, an overview on varius preparative and analytical application examples is presented.
