When chlorine (Cl2) gas is added to water during the disinfection of drinking water, it hydrolyzes with the water to form hypochlorous acid (HOCI). The disinfection power of the acid HOCI is 88 times better than its conjugate base, OCI". The pKa for HOCI is 7.5. Because the acidic form is a much better disinfectant, you want to maintain 89% of the total molar concentration in this form. What minimum pH should you target? Correct answer 6.6

In wastewater treatment plants, ammonium ion is removed from the water by raising the pH to form ammonia in an air stripping process described on p 65, in the textbook. This is the equilibrium reaction that describes the process of ammonium conversion to ammonia: NH4+ ⇄ NH3,aq + H+ Ammonia in the water then readily converts to ammonia gas, a) Plot a graph showing the concentration of ammonium ion as a function of pH. Use an Excel spreadsheet.b) If the wastewater pH is raised to 10, what fraction of ammonium ion did not react to form ammonia?

You are treating 10 million gallons per day (MGD) of water with alum at a dosage of 50.0 mg/L. Alum is available as a hydrated salt Al2(SO4)3.16H2O. Determine:(a) The monthly alum dosage required in metric tons/month (1 metric ton = 1000 kg)(b) If you assume that each equivalent of alum added to the water consumes 1 equivalent of alkalinity, determine the alkalinity consumed by alum addition in milliequivalents/L (meq/L)(c) Given that the raw water contained 30 mg/L as CaCO3 of alkalinity, is the alkalinity sufficient? What would happen if the alkalinity is inadequate?
For a solution with a pH equal to 9.5, express the concentrations of H+ and OH- in units of meq/L and mg/L as CaCO3.
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
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?…
Water with a dissolved oxygen (DO) concentration of 0.94 mg/L enters a well-mixed tankat a rate of 1500 L/min. The tank volume is 280 m3. In the tank, bacteria consume the oxygen for metabolism proportionally to the amount of oxygen present (if they use it at a rate r = k1 · DO, where k1 = 0.0021 min−1). Oxygen is dissolving into the water at a rate proportional to the degree of undersaturation (i.e., at a rate given by r = k2(DOsat − DO), where k2 = 0.0021 min−1 and DOsat = 8.5 mg/L. What is the steady-state concentration ofDO? Answer in units of mg/L.
