Tanfloc is a natural low molecular weight tannin polymer whereas Zetag and Flopam are both synthetic high molecular weight polyacrylamide polymers. Five exponential concentrations (0.55, 1.66, 5, 15 and 45 mg L<sup>- 1</sup>) were tested for freshwater <i>Chlorella vulgaris</i> and marine <i>Nannochloropsis oculata</i>. All polymers were efficient (> 90% at = 1.66 mg L<sup>- 1</sup>) for <i>C. vulgaris</i>. However, for <i>N. oculata</i>, only Tanfloc was effective. Charge density positively influenced flocculation decreasing the required polymer dosage. Restabilization was observed only for synthetic polymers when overdosed. Natural polymers performed similarly for both species. Overall, Tanfloc SL and Flopam FO 4990 SH were the most efficient polymers for microalgae flocculation though Tanfloc is a more economical option (US$37 per ton<sup>- 1</sup> of biomass) and environmentally friendly than Flopam (US$171 per ton<sup>- 1</sup> of biomass).","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Screening of commercial natural and synthetic cationic polymers for flocculation of freshwater and marine microalgae and effects of molecular weight and charge density","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Microalgae; Coagulation; Biopolymer; Harvesting; Dewatering","OtherDescriptors":null,"Notes":null,"AnaPub":2015,"MonPub":null,"DateUpdate":"2020-06-24","DateCreate":"2016-05-29","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000357989300024","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.algal.2015.05.008"},"refs":null,"anarec":{"AnaID":256953,"PubliDate":2015,"Pagination":"183-188","XtraPublOfAnaID":null,"ISBN":null,"Volume":"10","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":247867,"SerRR":"Algal Research.
