Calculate the removal efficiency for each of the parameters. Parameter Influent concentrations Unit Effluent concentrations Unit Gross pollutants (GP) 2 kg/m3 0 kg/m3 TSS 150 mg/L 20 mg/L TP 5 mg/L 3 mg/L TN 10 mg/L 2.5 mg/L If the flow is 20,000 m3/yr, determine the amount of the pollutants removed from the stormwater. Question 2. For the pond of area of 2000 m2 with an average depth of 4 m, determine the stormwater available for consumptive use. Need to maintain the permanent volume of 2500 m3 in the pond. The pond is located in Richmond RAAF area. Question 3. What should be length of a swale for reducing the TN concentration from 20 mg/L to 10 mg/L? Question 4.
