Chemical Oxygen Demand (COD): The COD concentration decreased significantly in the treated water as compared to the untreated wastewater (LSD 0.05 = 18.145) . The results showed that the activated sludge, sand filter and the activated carbon were effective for removal of COD from the wastewater.

the wastewater treatment process and soluble COD generally foundin the influent wastewater streams by recycling nitrate laden process flows to the head of the treatment system. However, in the MLE, step-feed and sequencing batch reactor (SBR) processes, a supplemental external carbon source might still be required to facilitate nitrate

For washing wastewater-2 with initial COD of 350 mg O 2/dm 3, the applied doses of acetic acid were 0.4, 0.8, 2.1, 4.2 and 8.3 cm3/dm . The doses of both ferric sulfate and hydrogen peroxide were lower amounting to 1.6 g/dm 3 and 20 cm/dm , respectively. The values of COD in the wastewater before and after the Fenton process are shown in Fig. 2.

If a large fraction of the BOD and ,COD, is contributed by inorganic reduced sulfur compounds such as sulfides, sulfides, or thiosulfate, then hydrogen peroxide alone is typically effective. Depending on the ,wastewater, pH, the oxidation of these compounds by H2O2 yields sulfate or colloidal sulfur, neither which contribute to BOD and ,COD,.
