Comprehensive Review of Membrane Fouling Control Mechanisms
Abstract: One of the biggest problems with membrane-based separation procedures is membrane fouling. As particles, organic matter, microbes, and other materials build up on the membrane’s surface or inside its pores, the effectiveness of membranes – such as those used in reverse osmosis, ultrafiltration, and microfiltration – declines over time. The effectiveness and longevity of the membrane are eventually lowered because of this fouling, which causes a drop in flux and …
