Purification of wastewater by natural flocculants

Polymeric Flocculants for Wastewater and Industrial Effluent Treatment

The fact that water is the most important material used by mankind defines the importance of water purification. Wastewater and industrial effluent treatment require removal of suspended solids for purification and possible re-usage. The removal can be accomplished by gravitation (very slow), by coagulation (dependent on electric charge situation) and by flocculation (not dependent on electric ...

Enhanced solid-liquid separation of dairy manure with natural flocculants.

The aim of this study was to determine the effectiveness of natural flocculants to reduce solids and nutrient loads in dairy cow wastewater using solid-liquid separation; chitosan was used as a model. Its use efficiency and optimum application rate were determined using flushed dairy cow manure of varied strengths - 0.4%, 0.8%, 1.6%, and 3.2% total solids (TS) content. Treatments consisted of n...

The Application of Cluster-Surfactant Flocculants in the Advanced Treatment of Coking Industrial Wastewater Reclamation

Coking wastewater from the process of coking, coal gas purification and the coking products refine, whose ingredients are complicated and inconstant, is hard to meet the standard of reclaimed water used for industrial water by secondary treatment. In view of this situation, the advanced treatment technique of coking wastewater was desired. The innovatory flocculation treatment was used to regen...
