Effect of Permeate Flux and Tangential Flow on Membrane Fouling for Wastewater Treatment
TLDR
In this paper, the effect of tangential flow and crossflow on membrane fouling was analyzed by the resistance-in-series model where the reason for flux decline was subdivided into adsorption, concentration polarization, and reversible and irreversible fouling.About:
