Abstract
Abstract: In this study, two definitions of critical flux were introduced based on the cross-flow microfiltration (CFMF) experiments conducted under an operational mode of constant permeate flux. The critical flux based on mass balance was calculated from the rate of particle deposition at a certain permeate flux. Below the critical flux, there will be no particle deposition on the membranes. The other was defined on the basis of the increase in transmembrane pressure (TMP). The critical flux based on the TMP increase is the flux below which membrane fouling does not occur. The critical flux based on both definitions was evaluated from experiments with different particle size, membrane pore size, influent concentration and ionic strength of the influent suspension.

The critical flux based on mass balance was calculated from the rate of particle deposition at a certain permeate flux. Below the critical flux, there will be no particle deposition on the membranes. The other was defined on the basis of the increase in transmembrane pressure (TMP). The critical flux based on the TMP increase is the flux below which membrane fouling does not occur. The critical flux based on both definitions was evaluated from experiments with different particle size, membrane pore size, influent concentration and ionic strength of the influent suspension.</p></abstract><textClass xml:lang="en"><keywords scheme="keyword"><list><head>Keywords</head><item><term>Critical flux</term></item><item><term>Cross-flow microfiltration</term></item><item><term>Particle size</term></item><item><term>Membrane pore size</term></item><item><term>Influent concentration</term></item></list></keywords></textClass></profileDesc><revisionDesc><change when="1999-12-05">Modified</change><change when="2000">Published</change></revisionDesc></teiHeader></istex:fulltextTEI><json:item><extension>txt</extension><original>false</original><mimetype>text/plain</mimetype><uri>https://api.istex.fr/document/3D89BF550271A9BD51461CED12C3282FD947B207/fulltext/txt</uri></json:item></fulltext><metadata><istex:metadataXml wicri:clean="Elsevier, elements deleted: ce:floats; body; tail"><istex:xmlDeclaration>version="1.0" encoding="utf-8"</istex:xmlDeclaration><istex:docType PUBLIC="-//ES//DTD journal article DTD version 4.5.2//EN//XML" URI="art452.dtd" name="istex:docType"><istex:entity SYSTEM="gr1" NDATA="IMAGE" name="gr1"></istex:entity><istex:entity SYSTEM="gr2ab" NDATA="IMAGE" name="gr2ab"></istex:entity><istex:entity SYSTEM="gr2cd" NDATA="IMAGE" name="gr2cd"></istex:entity><istex:entity SYSTEM="gr3" NDATA="IMAGE" name="gr3"></istex:entity><istex:entity SYSTEM="gr4" NDATA="IMAGE" name="gr4"></istex:entity><istex:entity SYSTEM="gr5" NDATA="IMAGE" name="gr5"></istex:entity><istex:entity SYSTEM="gr6" NDATA="IMAGE" name="gr6"></istex:entity><istex:entity SYSTEM="gr7" NDATA="IMAGE" name="gr7"></istex:entity><istex:entity SYSTEM="gr8" NDATA="IMAGE" name="gr8"></istex:entity><istex:entity SYSTEM="gr9" NDATA="IMAGE" name="gr9"></istex:entity><istex:entity SYSTEM="gr10" NDATA="IMAGE" name="gr10"></istex:entity><istex:entity SYSTEM="gr11" NDATA="IMAGE" name="gr11"></istex:entity><istex:entity SYSTEM="gr12" NDATA="IMAGE" name="gr12"></istex:entity><istex:entity SYSTEM="gr13" NDATA="IMAGE" name="gr13"></istex:entity><istex:entity SYSTEM="gr14" NDATA="IMAGE" name="gr14"></istex:entity><istex:entity SYSTEM="gr15" NDATA="IMAGE" name="gr15"></istex:entity><istex:entity SYSTEM="gr16" NDATA="IMAGE" name="gr16"></istex:entity></istex:docType><istex:document><converted-article version="4.5.2" docsubtype="fla" xml:lang="en"><item-info><jid>SEPPUR</jid><aid>1233</aid><ce:pii>S1383-5866(99)00088-X</ce:pii><ce:doi>10.1016/S1383-5866(99)00088-X</ce:doi><ce:copyright type="full-transfer" year="2000">Elsevier Science B.V.</ce:copyright></item-info><head><ce:title>Experimental determination of critical flux in cross-flow microfiltration</ce:title><ce:author-group><ce:author><ce:given-name>D.Y</ce:given-name><ce:surname>Kwon</ce:surname><ce:cross-ref refid="AFF1"><ce:sup>a</ce:sup></ce:cross-ref><ce:e-address>daeyoung.kwon@eng.uts.edu.au</ce:e-address></ce:author><ce:author><ce:given-name>S</ce:given-name><ce:surname>Vigneswaran</ce:surname><ce:cross-ref refid="AFF1"><ce:sup>a</ce:sup></ce:cross-ref><ce:cross-ref refid="CORR1">*</ce:cross-ref><ce:e-address>s.vigneswaran@uts.edu.au</ce:e-address></ce:author><ce:author><ce:given-name>A.G</ce:given-name><ce:surname>Fane</ce:surname><ce:cross-ref refid="AFF2"><ce:sup>b</ce:sup></ce:cross-ref></ce:author><ce:author><ce:given-name>R.Ben</ce:given-name><ce:surname>Aim</ce:surname><ce:cross-ref refid="AFF3"><ce:sup>c</ce:sup></ce:cross-ref></ce:author><ce:affiliation id="AFF1"><ce:label>a</ce:label><ce:textfn>Group of Environmental Engineering and Key Research Strength on Water and Waste Management, Faculty of Engineering, University of Technology Sydney, P.O.
