Suppose a wastewater enters a CSTR at a concentration of 100 mg/L BOD. The reactor volume is 5,000 m³ and the flow in and out is 625 m³/h. Calculate the steady state effluent concentration (expressed in ppm) if: the reaction rate is zero order and the rate coefficient is 4 mg L−¹ h¨¹. the reaction rate is first order and the rate coefficient is 4 h²¹. the reaction rate is second order and the rate coefficient is 4 L mg-¹ h¨¹. a. b. C.
