Proteins from Natural Coagulant for Potential Application of Turbidity Removal in Water

Coagulation-flocculation followed by sedimentation and filtration is the most commonly used water treatment process , in which turbidity or particles removal is strongly dependent on proper coagulant dosage, effect of pH ,effect of time, jar test and settling column tests were perform. In the method the seeds were treated with different solvents of NaCl and NaOH to extract the active coagulant agent has been investigated. In this study to evaluate the turbidity removal of the synthetic and real turbidity water has been investigated. The jar test was conducted on kaolin as a model wastewater. 0.5M Sodium chloride extract was found to provide a high turbidity removal of > 99% compared to NaOH and distilled water extract. The optimum turbidity removal at different values of initial synthetic wastewater turbidity from 100 to 500 NTU were investigated. The performance of natural coagulant after oil extraction was also investigated.
