| Summary: | A chicken slaughterhouse needs plenty of water to clean up the blood, feathers, and other waste products produced during the manufacturing of processed chicken. Therefore, chicken slaughterhouse wastewater discharged is suffered with certain unfavourable effects as a result of this sequence's constant repetition. Since the beneficial of electrocoagulation (EC) to the environment has being reported, many researchers have suggested EC system to be used in wastewater treatment prior discharged. However, less study was conducted on the EC of slaughterhouse wastewater for local Malaysian Industries. In this study, wastewater from a chicken slaughterhouse located in Alor Setar, Kedah was treated by using an EC process. The absorbance value, dissolved oxygen (DO) and chemical oxygen demand (COD) of the sample during EC under various conditions, including different electrode types, varying voltage levels, different treatment time, and distance between electrode was observed in this study. It was observed that the wastewater having absorbance wavelength with maximum peak of 345 nm detected by UV-Vis spectrophotometer analysis. The optimum condition for EC treatment was under Zn-Zn electrode set, 24 V, 6 min operating time and distance between electrode at 1 cm denoted as (a) conditional parameter, where the percent removal and COD removal of this parameter condition has shown the highest value (81.48% and 91.30% respectively) as compared with others. The composition and concentration of elements was detected by using ICP-OES for all samples. |
