The flocculation mechanism was analyzed, and theory that flocculation is interaction by clay, water and flocculant was presented.It was expounds that the adsorption bridging is the main way for mud flocculation dehydration. Conclusions that coupling force exists in basic unit body of the soil structure, and the force needs to overcome the coupling force in flocculation process were drawn. Mechanism analysis was explained by theories of polymer chain stretches when exposed to water and water film hypothesis.Read More
