This is in agreement with the published information that
non-ionic and anionic flocculants are not suitable to flocculate
the microalgae C. vulgaris, Chlorella fusca, Scenedesmus subspicatus
b Scenedesmus sp., which was obtained in (Granados et al., 2012).
Here, it is reported that polymer-based cationic flocculants proved
successful in microalgae harvest. Also, as shown in (König et al.,
2014), a weak-charged cationic flocculant FLOPAM FO 4240 SH
was most efficient (over 90%) at 2 mg/l and 4 mg/l concentrations
for Conticribra weissflogii microalgae. The successful use of cationic
PAA flocculants versus non-ionic and anionic agents was also
shown for Phaeodactylum tricornutum and Neochloris oleoabundans
microalgae. With 10 mg/l addition of Zetag 7557 and Synthofloc
5080H flocculants, the flocculation efficiency for P. tricornutum
was 98% and 94%, and 52% and 36% for N. oleoabundan, respectively
