Application of coagulation-microfiltration for membrane fouling . . . The CMF technique can effectively increase pollutant size and rapidly generate a cake layer via trapped flocs on the surface of membranes, greatly preventing direct contact of the membranes with fouling components of small particle size
Membrane Fouling Mechanisms in Combined Microfiltration-Coagulation of . . . In this paper, we investigated the membrane fouling mechanism according to the coagulant dosage in algal rich water using a ceramic membrane The algae that were used in this experiment were Microcystis sp of cyanobacteria, and the fouling
A review on mitigation of pressure-driven membrane fouling . . . The performance of coagulation flocculation, including its coupling processes with other pretreatment technologies, in controlling pressure-driven membrane fouling has been reviewed in detail according to fouling type (including inorganic, organic, and microbial fouling) in this paper
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 pretreatment could deteriorate reverse . . . Abstract Coagulation is widely regarded as an indispensable pretreatment process in reverse osmosis (RO) systems of zero liquid discharge applications Yet in practical applications, coagulation pretreatment often causes perplexing impact on membrane fouling and even deteriorates the RO performance with ambiguous mechanisms, thereby seriously disrupting the progress of RO-based applications
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
