Bioremediation of an Oil Water Separator – A Case Study

This case study is about the bioremediation of an oil water separator using Custom HC, a bioremediation product by Custom Biologicals.  Custom HC contains petrophilic, oil loving, bacteria. These oil loving bacteria have been specifically selected for use in bioremediation because of their enhanced ability to metabolize oil, petrochemicals, BTEX components and hydrocarbons.

The addition of bacteria to wastewater is called bioaugmentation, a form of bioremediation. In this case Custom HC was added to the oil water separator.

Bioremediation of an Oil Water Separator – A Case Study

Client Category: Industrial Wastewater – Truck Maintenance Yard

Location: Phoenix, Arizona, USA

Physical Plant: Two 350 gallon holding tanks leading to a 4,000 gallon oil/water separator.

Flow: 7,000 GPD average

Problem:  TPH (Total Parts Hydrocarbon) level of 180 mg/L caused a surcharge of $7,000.00 per year.

Pumping the oil/water separator monthly at a cost of $600.00 per month.

Previous Treatment: Pumping the oil/water separator monthly at a cost of $600.00 per month.

ustom HC was added daily to the holding tanks. A total of two 55 gallon drums were used each month. The product then flowed into the 4,000 gallon separator. Bionutrients were also added.

Custom Treatment: Custom HC was added daily to the holding tanks. A total of two 55 gallon drums were used each month. The product then flowed into the 4,000 gallon separator. Bionutrients were also added.

Custom Results: TPH decreased to an average of 23.3 mg/L within a 90 day period. The separator has not been pumped as of one year after beginning the treatment. The facility is now in compliance with city codes. Therefore, the surcharges have been eliminated.
