The average design flow at a wastewater treatment plant facility is 1.5 m3/s. The bar rack is mechanically cleaned with an average clear spacing of 2.5 cm. Estimate the average quantity of screenings that will be collected at each day.
The City of Smyrna discharges 0.16 m3/s of treated wastewater into Chattahoochee River. The BOD5 for the wastewater is 30 mg/L. The river has a 10-year, 7-day low flow of 0.16 m3/s. Upstream of the wastewater outfall from Smyrna, the BOD5 is 3.2 mg/L. The BOD rate constants k are 0.202 d-1 and 0.085 d-1 for the wastewater and creek respectively. The temperature of both the creek and the municipal wastewater is 20oC. Calculate the initial ultimate BOD after mixing

Assume the discharge from a wastewater treatment plant has aflow of 30 MGD with a solids concentration of 5 mg/L.a) Determine the mass flow rate of solids discharged in ton per day?b) Calculate the residence time of the pond in minutes?
Two communities, A and B, are found on two opposite sides of flowing river with a 9.10 m3 /s rate of volumetric flow, an uniform average speed of 0.25 m/s, an average depth of 4.0 m, an average temperature of 13°C, a chloride concentration of 8.0 mg/L, a 5.0 mg/L concentration of ultimate BOD, and an 8.0 mg/L concentration of dissolved oxygen. Both communities continuously discharge wastewater at the same point in the river where instantaneous mixing is assumed. The discharge of community A, which has an ultimate BOD of 48.2 mg/L and a dissolved oxygen concentration of 2.50 mg/L, is 2.10 m3 /s. On the other hand, community B discharges 1.80 m3 /s of wastewater, which has an ultimate BOD of 62.9 mg/L and a dissolved oxygen concentration of 1.50 mg/L. Just downstream of the downfall of both point sources, the deoxygenation rate constant is observed to be 0.22 day-1 .

The community of San Antonio is located in the Caranavi Province, Bolivia. According to the 2005 year survey, there are 420 habitants of the community. The population is estimated to increase to 940 by the year 2035. The average peak flow is currently 1.2 L/sec and is expected to increase to 2.14 L/sec by 2035. The organic load is estimated to be 45 gram BOD5/capita-day. The community is considering a free surface wetland to treat their wastewater. (a) What is the BOD5 loading generated in the year 2035 (kg/day)? (b) Use the BOD loading to estimate the maximum surface area (ha) required for a free surface wetland that would serve the community in 2035 and remove BOD to 30 mg/L. (c) Assuming you are now considering sizing a facultative lagoon instead of a free surface wetland. Quickly estimate the required surface area (m2) for a facultative lagoon to handle a peak flow in 2035, assuming a design water depth of 4 m and a hydraulic detention time of 20 days.
A stream flows through a small town where an industry dischargesits effluent into the stream. Upstream characteristics prior to industrial discharge are as follows: fow rate 1000 m3/d, BOD5 2.5 mg/L,nitrates 2.0 mg/L, and temperature 19°C. The industry dischargesat 50 m3/d. According to regulatory requirements, the maximumallowable values in the stream following any discharge are BOD5 30mg/L, nitrates 4.0 mg/L, and temperature differential of 4°C fromupstream conditions.

A University was opened on 21st March 2021. Due to the high number of students who reported at the main campus, there was waste water dischare into the universities River with dissolved oxygenconcentration of 2.0 mg/l at a discharge rate of 1.10m3/s from the stabilization ponds. After two days, there was another discharge downstream with dissolved concentration of 2.1 mg/l at a discharge rate of 1.20m3/s. After 1 hour a different discharge of waste with dissolved oxygen concentration of 0.5 mg/l at a discharge rate of 1.10m3/s was discharged in the River immediately after the second discharge point. The River that was receiving the waste had initial DO equal to 8.3mg/l, a constant flow of 8.70m3/s, and the temperature of 20' C. The saturated value of dissolved oxygen DOs at 20 ‘C is normally 9.09 mg/l. Just below the point where a continuous first discharge of pollution mixes with a river, the BOD was 10.9 mg/l. Using a deoxygenation constant of 0.20/day, an average flow of the mixture…
