A waste benzene solution is placed in a 55 gallon drum for transport. The initial BOD of the material in the drum was 150 mg/L. It was determined that this material will biodegrade at a rate of 0.12/day. The material was stored for 60 days and then transported to a treatment facility. What level of BOD was remaining in the tank? Draw a mass balance for the system Write the mass balance equation and simplify setting it equal to the concentration in the system. Determine the concentration of this material after 60 days.
