Effect of Pattern Shape on the Initial Deposition of Particles in the Aqueous Phase on Patterned Membranes during Crossflow Filtration

Patterned membranes for water treatment processes have been proposed to mitigate the detrimental effect of membrane fouling. Analysis of the effects of various pattern shapes on antifouling properties is required to achieve a higher resistance to fouling in these membranes. In this study, membranes...
