Web1 feb. 2024 · The fouling is generally related to the formation of a gel/cake layer by colloidal/particulate organic matter on the membrane surface, and adsorption/entrapment of small organic molecules within the membrane pore structure [ 5, 6 ]. WebMembrane fouling results in the requirement of pre-treatment of source water and membrane chemical cleaning, which incurs additional costs and increases energy consumption. Therefore, minimisation of the fouling is the key to success and cost-effective membrane operation [ 52 ].
