Benthasludge stabilization in the river Ganga at Kanpur

Field observations conducted at Kanpur, to analyze the ration of biochemical oxygen demand (BOD) contributions by benthasludge to the overlaying waters of the river Ganga were presented in part 1 of this paper. This data was later correlated to the data obtained under different conditions of operating and process variables in the laboratory. Observations were made at 3 sections along the river downstream of an outfall discharging partially treated wastewater.
