The discharge from the Renenutet sugar 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(L_w) 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.
PROBLEM #1 A stream receives a waste outfall which results in oxygen at saturation levels when mixed. The initial condition right after entry of the waste creates a BOD5 of 40 mg/l. KBOD is 0.3/day and KO2 is 1.3/ day. The stream temperature is 12 degrees centigrade. In terms of travel time when does the maximum DO sag occur? What is the minimum DO concentration in the river at the maximum sag point? If the average stream velocity is 3 feet per minute, what is the downstream location of the DO sag minimum relative to the location of the waste stream? Use the relevant equations provided in the textbook to solve this problem. Hint: Consider carefully what was stated in class about the BOD input for this type of problem.
