A drinking water treatment plant wants to compare the efficacy of three different solid coagulants, Alum [Al(OH)3(s)], Lime (CaCO3(s)), and Ferric Chloride (FeCl3(s)), for removing the phosphate (PO43-) level to 1 mg/L. The following are the equilibrium reactions [and the respective equilibrium constants (or solubility products, Ksp)] that result in phosphate removalfor each solid, the second reaction being more relevant in each case: Alum: Al(OH)3(s) ↔ Al3+ + 3OH- AlPO4(s) ↔ Al3+ + PO43- Ksp = 9.84 x 10-21 Lime: CaCO3(s) ↔ Ca2+ + CO32- Ca3(PO4)2(s) ↔ Ca2+ + PO43- Ksp = 1 x10-27 Ferric Chloride: FeCl3 (s) ↔ Fe3+ + 3Cl- Fe(PO4)(s) ↔ Fe3+ + PO43- Ksp = 1x10-26.4 What concentrations of Fe 3+, Al3+, and Ca2+ will be needed to maintain a phosphate concentration of 1 mg/L? What would be the best choice of solid coagulant for the Drinking Water Treatment Plant?…
A Haldane modification of the Monod reaction is often used to describe the kinetics of substrate utilization when the substrate itself is toxic at high concentrations (phenol is an example of this). (1) Calculate the effluent concentration for a substrate exhibiting Haldane kinetics from a CSTR (continuously stirred tank reactor) and (2) compare this with the value if the substrate were not inhibitory (S2/Ki = 0) for the following conditions: V = 24 m3 Q = 9 m3/d S0 = 400 mg/L Y = 0.5 mg/mg q = 7.5 g/g•d K = 7 mg/L b = 0.1 d-1 Ki = 15 mg/L Hint: θx = (active biomass in the system)/(production rate of active biomass) = V/Q And 1/θx = (YqS)/(K + S + S2/Ki) – b

An activated sludge treatment process uses a rectangular tank that can be modeled as two completely mixed reactors in series.
