Combination effect of flocculants for water treatment and development of compound flocculants

Abstract:

In the process of destabilization and aggregation of aquatic colloidal particles,different mechanisms of agglomerants,coagulants and flocculants were analyzed.Classification and representatives of coagulants and flocculants in water treatment were introduced from such aspects as chemical composition,molecular weight,production source and nature of functional groups.Different technical characteristics between combination effect of flocculants and compound flocculants were put forward.The properties and development of microbial compound flocculants and the combination effect between bioflocclant and other flocculants were investigated.
