# Oxidation of waste water

This content was COPIED from BrainMass.com - View the original, and get the already-completed solution here!

Assume that waste will contain 295.0 mg/L of biodegradable CH2O and will be processed through a 200000.0 L/day sewage treatment plant which converts 40% of the waste to CO2 and H2O. Calculate the volume (in Liters) of air (at 25 degrees C, 1 atm) required for this conversion. Assume that the O2 is transferred to the water with 20% efficiency.

Hint: Calculate mass of carbohydrate processed, use chemical equations to calculate mol oxygen needed to oxidize the carbohydrate, and the volume of air needed.
