Question

oxygen sag curve for water stream recieve sewage discharge

Answer 1

Hey.....!!!! :))

Oxygen sag curve:-

oxygen sag curve The curve obtained when the concentration of dissolvedoxygen in a river into which sewage or some other pollutant has been discharged is plotted against the distance downstream from the sewage outlet.

Importantance of oxygen sag curve:-

The differential equation for the dissolved oxygen sag curve (DO sag curve) is derived.

The discharge of a sewage effluent in a stream produces a biochemical oxygen demand (BOD) which decays exponentially in time and space. This oxygen demand causes anoxygen deficit, or oxygen shortage.
