Question:

The discharge from asugar beet plant causes the DO at the critical point to fall to 4.0 mg/L. The Meskhenet Stream has a negligible BOD and the initial deficit after the river and wastewater have mixed is zero.

What DO will result if the concentration of the waste(Lw) is reduced by 50%? Assume that the flows remain the same and that the saturation value of DO is 10.83 mg/L in both cases.
