Abstract

Background and objective: Today, with the development, the need for water in the production processes is increasing and so we have sewage with high level of pollution. This study aimed at determining the effectiveness of electrocoagulation for treatment of dairy industry wastewater in a continuous flow (case study wastewater of Sabah cheese factory Gonbad-e Qabus).

Materials & Methods: This study was descriptive and analytical with experimental approach. The samples were collected from Sabah dairy factory and put into the electrocoagulation reactor with continuous flow. At retention times of 20, 40 and 60 minutes with an electric current of voltages 20, 40 and 60 were purged. The samples were carried to the laboratory and various tests of COD, BOD, pH, turbidity, nitrate and phosphate were done. Then the results were compared and analyzed.

Results: The mean of COD, BOD, nitrates, phosphorus and turbidity was 4933 ± 231, 600 ± 50, 48.6 ± 14.8, 28 ± 0.7 mg/L and1329 ± 297.6 NTU respectively. The most removal efficiency of these parameters during the study was 84.62, 66.67,55, 54.2 and 85.1 percent respectively.

Conclusion:This study showed that electrocoagulation process as a pre-treatment process can remove organic matters, turbidity and nutrients. It can also reduce organic load and increase wastewater biodegradability and it can be an effective option for treating wastewater effectively and thereby preventing pollution in our environment and water resources.
