Abstract:

The impact of liquid wastes from a city sewage/ waste water on the benthic diatoms in flowing waters has been studied for a period a year (May 2015-April 2016). Water and algal samples were analyzed seasonally intervals at five sites along the course of the rivers Ganga, Allahabad. The hydrological strata of river water before the confluence of sewage / waste water were recorded low concentration of NH3 and other nutrients. At the entry of sewage/ waste water, the water showed considerable decline in dissolved oxygen content, increase in organic matter, hardness, CI, HCO3 and total dissolved solids. Diatoms constituted 61% by numerical abundance. Multiple regression analysis was employed to discover the relative importance of various physicochemical variables on the abundance and distribution of diatoms at various sampling stations. Mathematical equations were derived involving the physicochemical variables for better prediction of algal number.
