2. A totally oxygen deficient ground water source is decided to use as drinking water. In lab experiments, one step aeration resulted in increase of oxygen concentration from 15% of its saturation level to 32%. What would be the final oxygen concentration if the system is used as 2 steps aeration for the source? (Assume C = 11.3 g/m). Comment on final oxygen concentration. (30)
