摘要: Can we rely on the analysis of flux decline to evaluate risks a filter media be clogged during filtration given particle suspension? This important issue can dealt with macroscopic approach described in this paper. We seek identify and quantify successive prevailing mechanisms which occur run, directly solely from experimental data. is achieved collection data (filtrate volume V vs. time t) use differential equation (d2t/dV2) = k(dt/dV)n. A methodology then proposed define validate procedures purpose quantifying occurring fouling mechanism. For illustrating its valuable impact for bench marking procedure, has been applied model system composed bentonite suspension series microfiltration membranes different structures.
