Fouling and cleaning of ultrafiltration membranes: A review
TLDR
In this article, a review summarises the known facts about the fouling processes and cleaning procedures and details of the most successful physical and chemical cleaning combinations for one-stage and multi-stage UF membrane cleaning.Abstract:
Ultrafiltration (UF) is one of the best options for both one-stage and as part of multi-stage water and wastewater purification. This review summarises the known facts about the fouling processes and cleaning procedures and details of the most successful physical and chemical cleaning combinations. The optimum cleaning is closely linked to the nature of the fouling. Precise knowledge of both the fouling type (organic, inorganic, or biological) and the fouling mechanism (gel formation, adsorption, deposition, pore blockage, or cake formation) is the key to success in UF membrane cleaning.read more
