Problems arise if the contaminant concen- tration in the influent to the manufacturing step rises above a critical acceptable level (ca). Again, assuming that the contaminant con- centration in the municipal water is zero and that the UPW system does not remove any of this contaminant, solve for the recycle ra- tio (RR = R/Q) as a function of the other known quantities, Q, ca, and W. NOTE: for the purpose of answering this question, use "ca" to denote Ca.
Coagulant dosage and optimum pH were determined to be 50 mg/l of ferric sulfate [Fe2(SO4)3] and 6.6 respectively from Jar tests. The bicarbonate alkalinity in the water is found to be 20 mg/l as ion. The plant treats 40,000 m3/day of water and has 25 mg/l of suspended and colloidal solids. The ferric salt reaction in water is given below: (Atomic Weights: Fe-55.9, C-12, H-1, O-16, S-32, Ca-40) Fe2(SO4)3.xH2O + 6HCO3 − ⇔ 2Fe(OH)3(??) + xH2?? + 3SO4 2- + 6CO2 How much alkalinity (mg/l as CaCO3) will remain in water? If alkalinity is deficient then how much ferric salt will need to be neutralized and how do we neutralize the water?
6 Ydu will obtain 2.0 L of tap water for you water hardness test. The water hardness test uses a precipitation reaction to precipitate the Calcium bicarbonate present out of solution by adding 1.9 g of Ca(OH) represented by the following equation: Ca(HC03|21ag) + Ca(OH)215) > 2CaCOsisi + 2 H20 ml What is the percent yield of CaCO3 produced in the hard water test?

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?…
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?
A Pump & Treat water treatment system at a contaminated site is designed to treat 5 m3/d of ground water in a reactor designed as a well mixed system. The effluent must meet quality standards of 25 mg/L of Iron. The treatment reactor’s 20 m3 volume is believed to be insufficient to achieve the standard. The ground water has an iron concentration of 100 mg/L and the treatment reactor has a kinetic constant of 0.5 d-1. – Confirm that the treatment system will NOT meet the effluent quality standards. – If not modify the design by adding a PFR system (using same treatment process and kinetics), what volume should the PFR addition be?
An ion exchanger treats 1 MLD of water using an exchanger of capacity 100 kg/day/m3 with rate of flow being 0.5 m3/min/m2. Choose the correct statements assuming total hardness of water equal to 84 mg/1 as Cao. Total hardness of water is equal to 150 mg/l as CaCO3. Correct Option B Sodium Alumino - Silicates may be used as ion-exchanger. Correct Option lon exchanger can result in removing complete hardness. Correct Option Correct Option The height of ion exchanger required is 1.08 m if hardness of water is taken as 150 mg/1 as CacO3.

2. Cadmium is a pollutant of concern in mining. The initial concentration of cadmium in a mining wastewater (also called acid mine drainage) is 0.1 mg/L, and the EPA Maximum Contaminant Level (MCL) is 0.005 mg/L. What must the pH be so that the wastewater does not exceed the EPA MCL? Given: Cd(OH)2 → Cď²* + OH (unbalanced) K, = 5.33 x 1015 Cd(OH)2: Cd2+ = 112.4 g/mol 17.0 g/mol = 146.4 g/mol OH- =
