Sewage contains liv- ing matter, especially bacteria and protozoa. Domestic sewage has been reported to contain about 250-400 ppm of organic carbon and 80-120 ppm of total nitrogen, resulting in a C/N ratio of around 3:1. Industrial sewage may contain more organic carbon and hence may have a higher C/N ratio.
