1. An effluent water contains significant quantities of non-emulsified oil with a concentration of 176 mg/l. In order to maintain the concentration of the oil below 25 mg/l, alum with a dosage of 35mg/l was used. Based on the preliminary experiments it was found that every gram of alum produces 0.65 g of sludge. The weight percentage of sludge in the effluent is 2.75. The flow rate of oily effluent water to the treatment unit is 0.75 m3/min at 30°C....

3. (40 points) The mass concentration in mg/L of a carbon compound (C6H12O6N2) measured in a water sample is three times higher than NH3 mass concentration. The ThoD for both carbon and nitrogen oxidation are 384 mg/L. What is the concentration of NH3 (mg/L) in water sample? (Molecular weight: C6H1206Nz=208; NH; = 17; O2 = 32) Assume, NH3 concentration = x mg/L C6H12O6N2 concentration - 3x mg/L NH3 C6H12O6N2 + 02 NH3 + O2 → + CO2 + H2O +...
