The effect of operating conditions on turbidity removal by polymeric flocculant

Since there are many factors which influence the process of flocculation by polymeric flocculant, the scientific understanding of the flocculation mechanism is still under discussion. We have proposed a simple bridging model which expresses flocculation under various additive manners of the floccula...
