An industry produces 369 m³ of wastewater everyday with a BOD of 1.5 kg/m³ population equivalent of industrial sewage? 6191 persons 7191 persons 6919 persons 7191 persons What is the

An industry is discharging 2500 m3/d wastewater into a sanitary sewer. The concentrations of BOD5, TSS, TN, and TP are 200, 280, 35 and 10 mg/L, respectively. Calculate the population equivalent of the industry based on flow, BOD5, TSS, TN, and TP (i.e., number of people served). Assume that the unit waste loadings in terms of g per capita per day are 95, 104, 18, and 4 for BOD5, TSS, TN (as N), TP (as P), respectively.

You are building a wastewater lagoon with an inlet/outlet flow rate of 3,100 m3/day. The BOD inlet load is 26 mg/L and you need to achieve 12 mg/L at the outlet. The half-life of BOD is 2.4 days. What is the volume required for the lagoon? If the wastewater stopped entering the lagoon and was replaced by freshwater, how long would it take for the outlet BOD concentration to reach 1 ppm?

please explain while solving

The ultimate BOD of two wastewaters is 280 mg/L but their K values are 0.1/d and 0.23/d at 20oC. Calculate 5-day BOD for each of the wastewater. What you conclude based on your answer?

You are constructing a sewage lagoon with a 3,100 m3/day inlet/outlet flow rate. You must attain a BOD outflow load of 12 mg/L given a BOD inlet load of 26 mg/L. BOD has a half-life of 2.4 days.What volume is needed for the lagoon and how long would it take for the output BOD concentration to reach 1 ppm if freshwater started to replace the wastewater that was previously entering the lagoon?

A wastewater treatment plant serving a population of 50000 receives a per capita flow of 240 L/d and per capita BOD5 loading of 64.8 g/d. What is the BOD concentration of sewage entering the treatment plant?

Explain shortly thank you very much
