Abattoir wastewater (AWW) contains a high level of organic pollutants due to the presence of toxic contaminants such as blood, feces from animals, and detergents from cleaning activities. In this study, the wastewater from the slaughterhouse was treated with a cobalt-catalyzed persulfate oxidation reaction to determine how well persulfate works as an oxidant to get rid of and break down organic materials. The water tested had a high organic load (COD = 2100mg/L), a pH of 7.7, and a BOD of 800mg/L. Time (10–90min), temperature (25–75°C), acid content (0.5–2.5M), persulfate (0.025–0.1g), and cobalt catalyst (50–150 mg/L) were all evaluated as operational conditions. Temperature and acid content was found to have a positive effect on COD elimination while increasing the residence time. The reaction conditions were optimized at a constant dose of 0.3 g of potassium persulfate, 1 M acid concentration in 30 minutes, and a maximum temperature of 60°C. At optimum conditions, approximately 98.46% of the COD was removed. The COD elimination rate was 92.85% at a low amount of potassium persulfate (0.075g). The study concludes that the developed approach could be used to efficiently treat abattoir wastewater.
