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.

Answer (1) syed seerat 14th Mar, 2019. A common depressant used in the froth floatation of lead sulphide is sodium cyanide. When the ore containing ZnS and PbS is subjected to froth floatation process in the presence of NaCN, then only PbS forms the froth. This happens because NaCN reacts with ZnS to form Na2 [Zn (CN)4].
