The highest, COD, removal was observed in slightly, acidic, pH conditions. The maximum, reduction, efficiency of, COD, was accomplished with unmodified clinoptilolite-rich tuff at a contact time of 1440 min. In these conditions, the adsorbent was efficient for treating, wastewater, from a slaughterhouse.

Higher, COD levels mean a greater amount of oxidizable, organic, material in the sample, which will reduce dissolved oxygen (DO) levels. A reduction in DO can lead to anaerobic conditions, which is deleterious to higher aquatic life forms. The COD test is often used as an alternate to BOD due to shorter length of testing time.

concentrations. In the first series, three pollution strengths of ,wastewater, such as 5, 20 and 100 % were prepared for ,COD, removal at the fixed ,COD,/H 2O 2 ratio of 1/2. In the second series, hydrogen peroxide was added in ,COD,/ H 2O 2 weight ratios of 1:1, 1:2 and 1:4. The initial ,COD, concentration was kept constant at 1050 mg l-1.

In the overall treatment process under optimized conditions, the, COD, of oily, wastewater, was reduced from 4,314 to 637 mg/L, and the, COD, removal efficiency reached 85.23%. The contribution of each stage is 68.45% (micro-electrolysis), 24.07% (Fenton oxidation), 7.48% (coagulation), respectively.
