A customer had 30,000 barrels of process/sump water in a terminal station tank that needed to be de-inventoried. The original plan was to haul the hazardous process water off-site to a waste treatment facility.
Instead, Envent proposed treating and discharging the water at a fraction of the cost. Envent acquired the discharge permit to ensure regulatory compliance. The process water was then successfully treated using a combination of air flotation, filtration pods, clay media and granular activated carbon.
Approximately 1 million gallons of clean water was discharged to the POTW and an estimated $450,000 was saved when compared to transportation costs.
