Cationically branched starch-based flocculants for synergistic . . . CS-ECH efficiently alleviates ultrafiltration membrane fouling resistance CS-ECH produces large but loose dye flocs because of its distinct branched structure Bridging and sweeping effects of CS-ECH are enhanced besides charge neutralization
A Comprehensive Review on Membrane Fouling: Mathematical . . . - MDPI This paper presents a review of the different membrane fouling types, fouling-inducing factors, predictive methods, diagnostic techniques, and mitigation strategies, with a special focus on RO membrane fouling
Insights into the Mechanism of Coagulation Pretreatment for Membrane . . . Herein, the coagulation-ultrafiltration combined process (C-UF) was applied to the actual lake water treatment, and a novel polyaluminum titanium composite coagulant (PATC) was used as a pretreatment reagent for membrane fouling mitigation
Coagulation flocculation prior to low pressure membranes in drinking . . . This section discusses the impact of coagulation flocculation configuration types on membrane fouling in terms of resistance (i e resistance to flow), fouling rate, as well as hydraulically and chemically reversible irreversible fouling
In-line coagulation assessment for ultrafiltration fouling reduction to . . . The impact of four coagulants at different dosages on reversible and irreversible membrane fouling and permeate quality was studied It was found that in-line coagulation improved UF performance to varying degrees depending on coagulant type and dosage
