An industry wants to reduce the concentration of contaminant X in their waste stream. They have found two ways to do this: Option #1 – Place X in a batch reactor, add compound Y, and compound X decays via zero order kinetics Option #2 – Place X in a batch reactor, add compound Z, and compound X decays via first order kinetics. For both options, it was found that the concentration of X decreased from 80 mg/L to 30 mg/L in one hour. If the permit level for discharge is 1.0 µg/L, which option do you choose and how long do you need do treat for?

An industry wants to reduce the concentration of contaminant X in their waste stream. They have found two ways to do this:
- Option #1 – Place X in a batch reactor, add compound Y, and compound X decays via zero order kinetics
- Option #2 – Place X in a batch reactor, add compound Z, and compound X decays via first order kinetics.
For both options, it was found that the concentration of X decreased from 80 mg/L to 30 mg/L in one hour. If the permit level for discharge is 1.0 µg/L, which option do you choose and how long do you need do treat for?
