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.

A small lake with volume 10,000 m3 has a stream flowing into it with flow rate 100 m3/day and a Toluene concentration of 1.0 mg/m3. A factory discharges 5 m3/ day into the lake with Toluene concentration of 10 mg/m3 - they want to increase effluent to 50 mg/m3. Toluene decays at a rate of 0.01 day-1. Assume steady-state and completely mixed (CSTR). a) How would this increase in discharge concentration change the lake concentration? Answer: 0.73 mg/m3 before, 1.71 mg/ m3 after b) Field studies show that the same lake would be better represented by dividing the lake into two cells. The first cell having a volume of 2,500m3 and the second with 7,500m3. How does this affect the estimate of concentration leaving the lake? Compare with one- cell model. Assume the factory continues to discharge at 10 mg/m3 into the first cell.
