Abstract

Ceramic industry wastewaters not only contain high total suspended solids but also significant amounts of dissolved organics resulting in high BOD or COD loads. Suspended solids can be removed from the wastewater by chemical precipitation. However, dissolved BOD/COD compounds can only be removed by biological or chemical oxidation. Effluent wastewater from chemical sedimentation stage of ceramic industry was characterized and subjected to biological treatment in a laboratory scale activated sludge unit. Experiments were conducted at different conditions and solids retention times. The best results were obtained with mixed liquor suspended solids 3000 MLSS and 6 hrs. of solids retention times (sludge age) resulting in effluent COD and BOD concentration of 0 mg/l from a feed wastewater of 4000 mg/l COD and 150 mg/l BOD contents.
