摘要:This is a comparative study with the effluent treatment plant using electro-coagulation EC) and chemical coagulation (CC). The study was conducted at Gazipur district and Savarupazila of Bangladesh to find out the water chemistry of effluent and treated water and makes a comparison with the DOE standard for surface and irrigation water. Find out of sludge characteristics was one of the other objectives of this study. Sample collection was done within the month of October to November, 2013 and general lab test of water and sludge were done at Asia Arsenic Network (AAN) in Jessore. In water analysis part it was observed that the electric conductivity, TDS, color and turbidity was better for the chemical coagulation process and sulfate, DO, BOD, COD, TSS, sulfide, chloride condition was better in electro-coagulation process. Bacteria removal efficiency was noticeable in the electro-coagulation process than the chemical coagulation process. In sludge the pH, conductivity, TDS was slightly higher in CC process than the EC process. The water analysis part will be helpful to give a suggestion that effluent treatment plant (ETP) using EC process is better than the ETP using CC process in the perspective of treated water quality and environmental issue.
