OSTI ID:85980
In many parts of the world, chemical oxygen demand (COD) is a primary effluent parameter. Unlike BOD, which considers only biodegradable organics, COD also includes non-degradable organics and non-degradable biological oxidation by-products, generally referred to as soluble microbial products (SMP). The SMP can vary from 2% to 10% of the influent degradable COD. If the technology is limited to biological treatment only, the degradable COD will be removed. Further reductions in COD will require physical chemical treatments such as activated carbon. Effluent COD values for several industrial wastewaters are presented. Effluent characteristics from the anaerobic treatment of industrial wastewaters are also discussed.
