Abstract
Reverse osmosis and microfiltration are two membrane-based separation techniques that have gained popularity over the past few decades. A fundamental barrier to improving the overall efficiency of membrane separation is membrane fouling. The accumulation of foulants causes a reduction in permeate flux, a loss of selectivity and permeability, and a reduction in the membrane’s lifespan. Numerous chemical and physical surface changes have been studied to enhance membrane antifouling properties. Additionally, research has concentrated on creating membranes that use cutting-edge materials to improve their antifouling capability. This paper focuses on a wide-ranging and thorough analyses of the different types of fouling during wastewater treatment based on current research results regarding fouling control strategy and the potential of new methods for wastewater treatment. It is a further step forward for the evaluation of mitigation measures for emerging membrane fouling problems.
