A BOD test was conducted on the unchlorinated effluent of a municipal wastewater treatment plant at 20°C. The wastewater portion added to a 300-mL BOD bottle was 30 mL, and the dissolved oxygen (DO) values listed below were measured using a dissolved-oxygen probe. No seed was added to the bottles. What is the BOD value for each “valid” sample? Valid samples are ones that do not violate the following two rules: 1. DOf is less than 1.0 mg/L (unclear if...

What is the effluent concentration of a reactive contaminant exiting a completely mixed flow reactor after 8 hours of operation? Assume that after this length of time, the reactor is at steady state. The volume of the reactor is 100 L and the volumetric flow rate is 50 L/hr. The influent concentration of the contaminant is 80 mg/L and the rate constant for the decay of the contaminant is 0.5 hr-1.

A river containing 1.7 mg BODL/L and 6.8 mg DO/L receives a 6.4-ft3 /s agricultural effluent containing 210 mg BODL/L and 2.5 mg DO/L. The river is on average 175 ft wide, 4 ft deep, and it flows at 0.12 ft/s. We assume for simplicity that the temperature of the river and effluent is 20°C, with DOsat (20°C) = 9.1 mg/L, kd = 0.3 d-1 , and ka = 0.25 d-1 . a) Following the steps below, you are asked...

A domestic wastewater source has 550 mg L-1 BOD, 60 mg L-1 total nitrogen (comprising Total Kjeldahl Nitrogen (TKN), nitrate and nitrite, and ammonia) and 15 mg L-1 soluble phosphorus (SP). These parameters need to be brought to < 30 mg L-1 BOD, < 15 mg L-1 for total nitrogen, <1 mg L-1 for ammonia, and < 2.5 mg L-1 for SP before being discharged into a local river. Investigate possible wastewater treatment methods that could be applied to remove...

A dairy in Fresno County discharges its wastewater to a circular treatment pond. The dairy wants to expand its operations, which will increase the influent flow but not the influent concentration. What is the maximum influent flow that can be handled by the existing pond in the future without exceeding the legally allowed effluent concentration of 30 mg/L. Data on the existing facilities and flows are shown below. The soil is sandy and there is considerable seepage. The wastewater pollutants...
