This study looked into the possibility to add the already flocculated
biomass into microalgal culture broth. Thus, the biomasses
added were both flocculated by different flocculants, and those
flocculated by coagulant and flocculant mixtures. In one case, it
was biomass flocculated by agents that showed their efficiency,
in particular, Superfloc C-492, Sibfloc-718 and FeCl3. Also, the
experiments used the mixture that also proved to be the most efficient
earlier, i.e., Sibfloc-718 and FeCl3.
