1. A commercial laundry is consdiering constucing an ion exchange process to remove hardness from water used in laundering oerpations. The laundry uses 1000 m³/d of city water with Ca²+ at 4.5 meq/L and Mg²* at 2 meq/L. Their goal is to reduce total hardness (TH) to 1 meq/L. The softening resin has a TH capacity of 60 kg-TH/m³ of media with a recommended hydraulic loading rate of 0.4 m³/(m² min). Renegeration can be accomplihsed using 100 kg NaCl per m³ of ion exchange media in a 15% solution at a hydraulic loading rate of 0.04 m³/(m² min). The exchanger tanks available to the laundrey have a diamter of 1 m. What is the total bypass-water flow rate (m³/d)? What is the total daily resin volume required to soften the water (m³/d)? How many exchanger tanks are required for a one-day operation cycle? What is the resin bed depth (m) in each exchanger tank? What is the daily volume of NaCl regenation solution used per tank (m³/d)? What is the time period required for resin regeneration in…

You are being consulted for the design of a coagulation-flocculation basin for a water treatment plant. Ferric sulfate is available as a commercial coagulant and is popular at removing turbidity and color. The chemical reaction for its addition to water is: Fe2(SO4)3 + 3Ca(HCO3)2 ----> 2Fe(OH)3 (s) + 3CaSO4 + 6CO2Results of a jar test to determine the optimal coagulant dose are provided below. The initial water sample has a pH=6.5 and turbidity of 30 NTU. Ferric sulfate dose, mg/L: 5 10 15 20 25Turbudity, NTU: 15 5 1 0.9 2What is the optimal mass of ferric sulfate you would need to purchase every day to treat 106 gallons/day to a turbidity below 1 NTU (assume 100% purity of the coagulant).
Lake Bonaventure is a lake fed by the Saint Croix River. The Acme smeting company discharges the heavy metal nickel into the lake. The easy way to model the concentration of nickel is to assume the lake is well mixed. It isn’t. The lake has a mean depth of 30m, and during the summer a surface epilimnion of 5m develops, which breaks down for the winter. (no calculations are required to answer the questions below) (A) Given what you know about the hydrology of lakes, what differences in concentration would there be if the smelter discharges at the surface or at a depth of 30m? (B) How would concentrations vary in the lake throughout the year? (C) What if you factor in the fact that the flow of the Saint Croix River is less during the winter?

A water with low alkalinity of 15 mg/L as CaCO3 will be treated with the ferrous sulphate-lime coagulation. FeSO4 dosage is 18 mg/L. (CaCO3 = 100 g/mol, Ca(HCO3)2 = 162 g/mol, Ca(OH)2 = 74 g/mol, FeSO4.7H₂O = 278 g/mol, Fe(OH)2 = 90 g/mol). a. Determine the lime dosage needed to react with the ferrous sulphate for sweep coagulation. b. If dissolved oxygen (DO) concentration is 5 mg/L before coagulation, what is concentration of DO after coagulation?
