17.1. In a system with recycle, the following data on inert (nonbiodegradable inorganics that originated in the influent) solids concentrations were obtained: Xino = 20 mg L- Xne = 0 mg L- Xnr = 100 mg L- The system is at steady state and the clarifier is ideal. What are the values for Qw and Xin, if Q is 0.35 m3 s=1 and the recycle ratio, r, is (l) 0.5 (ii) 1.0? Does the flow regime (i.e., CM or PF) in the reactor make any difference? If it does, perform the calculations for each regime
