Deformation-induced cleaning of organically fouled membranes: Fundamentals and techno-economic assessment for spiral-wound membranes

Membrane fouling is a ubiquitous challenge in water treatment and desalination systems. Current reverse osmosis (RO) membrane cleaning technology relies on chemical processes, incurring considerable costs and generating waste streams. Here, we present a novel chemical-free membrane cleaning method applicable to commercially existing RO spiral-wound membrane modules. The method employs controlled membrane deformation through pressure modulation,...
