Effect of intermittent addition on turbidity removal by polymer flocculant: computer simulation of simplified flocculation model

Since there are many factors which influence the process of flocculation by polymer 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 flocculant...
