Alkaline flocculation is induced by an increase in pH and is related to precipitation of calcium and magnesium salts. In this study, we used the diatom <i>Phaeodactylum tricornutum</i> as model organism to study alkaline flocculation of marine microalgae cultured in seawater medium. Flocculation started when pH was increased to 10 and flocculation efficiency reached 90% when pH was 10.5, which was consistent with precipitation modeling for brucite or Mg(OH)<sub>2</sub>. Compared to freshwater species, more magnesium is needed to achieve flocculation (>7.5 mM). Zeta potential measurements suggest that brucite precipitation caused flocculation by charge neutralization. When calcium concentration was 12.5 mM, flocculation was also observed at a pH of 10. Zeta potential remained negative up to pH 11.5, suggesting that precipitated calcite caused flocculation by a sweeping coagulation mechanism.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Alkaline flocculation of <i>Phaeodactylum tricornutum</i> induced by brucite and calcite","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:32:52.928458","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Coagulation; Marine algae; Enmeshment; Biomass; Autoflocculation","OtherDescriptors":null,"Notes":null,"AnaPub":2015,"MonPub":null,"DateUpdate":"2018-08-29","DateCreate":"2016-05-29","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000361040500082","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.biortech.2015.08.042"},"refs":null,"anarec":{"AnaID":256832,"PubliDate":2015,"Pagination":"656-661","XtraPublOfAnaID":null,"ISBN":null,"Volume":"196","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42269,"SerRR":"Bioresource Technology.
