The AOC/DOC ratio was in the order of F.LMW (similar to 35%) > F.BP (similar to 19%) > F.HS&BB (similar to 8%); AOC/DOC of seawater was similar to 20%; organic compositions of seawater were BP similar to 6%, HS&BB similar to 52% and LMW similar to 42%; LMW accounted for >70% of AOC in seawater. Their impact on SWRO biofouling in term of flux decline rate was in the order of F. LMW (similar to 30%) > F.BP (similar to 20%) > F.HS&BB (<10%). Despite being the major organic compound in seawater, HS&BB showed marginal effect on biofouling. The role of indigenous BP was less critical owing to its relatively low concentration. LMW, which was the major AOC contributor, played a significant role in biofouling by promoting microbial growth that contributed to the build-up of soluble microbial products and exopolymeric substances (i.e., in particular BP). Therefore, seawater pretreatment shall focus on the removal of AOC (i.e., LMW) rather than the removal of biopolymer.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Impact of isolated dissolved organic fractions from seawater on biofouling in reverse osmosis (RO) desalination process","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-17 01:32:29.977798","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Biofouling potential; Seawater desalination; Reverse osmosis; Naturalorganic matter; Assimilable organic carbon; Organic transformation","OtherDescriptors":null,"Notes":null,"AnaPub":2020,"MonPub":null,"DateUpdate":"2020-04-14","DateCreate":"2020-04-07","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000498308000049","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.watres.2019.115198"},"refs":null,"anarec":{"AnaID":322802,"PubliDate":2020,"Pagination":"115198","XtraPublOfAnaID":null,"ISBN":null,"Volume":"168","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":44009,"SerRR":"Water Research.
