Description:

In the past, residual chemical heels in tank cars were washed out of the tank cars and the wastewater generated was sent to the wastewater treatment plant for treatment (anaerobic and aerobic). A header system was installed to facilitate collection of these heels such that these chemicals could be reprocessed in one of the existing operating units. Recovery of these chemicals has reduced the loading on the wastewater treatment system.

Environmental Benefits:

Installation of this project has reduced the annual TOD (total oxygen demand) loading to the wastewater treatment plant by approximately 320,000lbs annually.

Details of Reductions

Additional Information :

Savings due to recovery of residual chemical heels is approximately $5,000 per year.
