·The biopolymer produced by Anabaenopsis circularis strain PCC 6720 was found to be an effective anionic flocculant for bentonite suspensions The presence of CaCl 2 increased the flocculation efficiency significantly From adsorption isotherms and zeta potential measurements it was concluded that the flocculation process is based on the bridging

·Chitosans with different degrees of deacetylation DD and molecular weights M w were tested for the flocculation of bentonite suspensions prepared with demineralized water DW and tap water TW kinetics model of particles collisions combining zeta potential and turbidity measurements was employed to investigate the effects
·Simple flocculation can be achieved by charge neutralization bridging sweeping hydrophobic aggregates and other approaches [17] [22] [31] [32] However selective flocculation is a complex process and has complex mechanisms and technology including identification/design of agents based on the surface chemistry of particles use of site blocking
