Evaluation of flocculation induced by pH increase for harvesting microalgae and reuse of flocculated medium
TLDR
This study revealed that the microalgal biomass concentrations and released polysaccharide from microalgae could influence the flocculation efficiencies, and neutralizing pH and then supplementing nutrients allowed the flocculated medium to maintain an approximate growth yield to that of the fresh medium in algal cultivation.About:

Harvest of Scenedesmus sp. with bioflocculant and reuse of culture medium for subsequent high-density cultures
TL;DR: The results suggest that the flocculation method presented here is efficient and bio-friendly, and allows the reuse of the flocculated medium, thereby contributing to the economic cultivation and harvest of microalgae.

Evaluation of the production, composition and aluminum and iron complexation of algogenic organic matter
TL;DR: There is a significant difference in the amount and properties of the proteins contained in EOM in comparison to IOM, and the demonstration of AOM affinity to aluminum and iron coagulants is demonstrated.

Effects of harvesting method and growth stage on the flocculation of the green alga Botryococcus braunii
TL;DR: Results indicate that the most effective harvesting method is to adjust pH to 11 after 2 weeks of incubation, and an optimal growth stage for the recovery of the green alga Botryococcus braunii growing in batch cultures is found.
Interaction of humic substances with cationic polyelectrolytes.
John Gregory,SK Kam +1 more
TL;DR: The charge densities of a commercial humic acid and an aquatic humic extract have been investigated by studying their interactions with a series of synthetic cationic polyelectrolytes and the techniques used were colloid titration by spectrophotometry and streaming current detection and flocculation determined by colour removal and by an optical monitoring method.

The interaction of humic substances with cationic polyelectrolytes.
Sang-Kyu Kam,John Gregory +1 more
TL;DR: In this paper, the anionic charge carried by aquatic humic substances plays a major part in their interaction with metal ions and other cationic species, and removal of such substances by coagulation and flocculation can be, at least partly, determined by charge neutralisation.
