A wastewater treatment plant discharges 20,000 m3/d of treated sewage into a river. The effluent’s BOD is 25.0 mg/L. The river’s flow and velocity are 5,500 m3/d and 23 km/hr, respectively. At the point of the effluent discharge, the river’s BOD and DO are 2 mg/L and 6 mg/L, respectively. The river’s water temperature is 25 °C. The deoxygenation coefficient, kd, was determined to be 0.45 day-1, and the reaeration coefficient, kr, is 0.52 day-1. Apply the plug flow model assumptions and calculate the the oxygen deficit at the point of the effluent discharge, the BOD at the point of the effluent discharge, the critical time and distance and minimum DO level.

Compute the WQI (water quality index) for a water stream with the characteristics described below using the weighted linear sum approach by using the WQI link ( https://water-research.net/index.php/water-treatment/water-monitoring/monitoring-the-quality-of-surfacewaters ) Dissolved oxygen: 85 % saturation Fecal coliforms: 1000/100 mL pH: 6.95 BOD5: 25 mg/L Nitrates: 15 mg/L Total phosphates: 2 mg/L Temperature deviation: +1.00C Turbidity: 10 NTU Total solids: 250 mg/L What is the descriptor for the surface water body? Briefly comment on your results. Based on the tool output, which are the tree factors that currently are more detrimental to water quality? NOTE: I calculated the WQI using the link, WQI=56. Please check.
Biological parameters are important factor that determine quality of water. It is more important than physical and chemical parameters in term of direct effect on human health. Some biological characteristics include bacteria, protozoa, virus and algae. Explain three effects of biological parameters on water quality.
Dissolved chloride in a concentration of 500 mg/L is being advected with flowing groundwater at a seepage velocity of 0.3 m/d in an aquifer with a porosity of 0.25. Groundwater from the aquifer discharges into a river. a. What is the mass flux of chloride into the river (in g/(m2d))? b. How long does it take the chloride to travel 100 m through the aquifer (i.e., the travel time for a 100 m distance)?
Drinking water from a dam which undergoes conventional treatment has a computed chlorine demand (due to silt, corrosion and bacteria) amounting to 3.5 ppm. Per PNSDW, such drinking water must have a mandatory chlorine residual of 1.0 ppm at source. If production flow is at 500 cu.m./day, calculate the chlorine dosage needed in pounds per day (PPD).
Assume the described is at steady state. A fluid goes up to an aquifer that has groundwater and a chloride concentration of zero. The groundwater reservoir is 20,000 m^3 and has an outflow of 2 m^3/hour. If the fluid has a chloride concentration of 0.04 M and the aquifer outflow has 0.0084 M, how much chloride is precipitated in the reservoir? Any missing chloride is due to chemical reaction consumption.
A company is currently discharging 200 L/min of 100 mg/L contaminant into a river. The river flowing past the company has an upstream flow rate of 3800 L/min with 0 mg/L of the target contaminant. The company must reduce its effluent concentration to below 20 mg/L (a) what is the current contaminant concentration past the point of discharge? (b) How much clean water would be needed to dilute the contaminant stream to 20 mg/L.? (c) What would be the contaminant concentration past the point of discharge if the company's contaminant stream was diluted with the water in part b?
