Bioremediation of an Oil Water Separator – Case Study

The Bioremediation of a Oil Water Separator – A Case Study

This case study involves the use of Custom-HC, a bioremediation bacterial product, in a oil water separator. Oil water separators are deigned to keep oil, fuel oils, and hydrocarbons out of municipal sewage systems. Oil water separators are a form of industrial wastewater treatment and work because of the different densities of water and oil.

The generally accepted method to maintain the oil water separator is simply to pump it out periodically. This is expensive and unnecessary. Bioremediation, the use of specific bacteria to metabolize oil, is as less expensive and efficient process of maintaining oil water separators.

Custom HC, a bioremediation product of Custom Biologicals, is the bioremediation bacteria used in this case study. Custom HC contains petrophilic, oil loving, bacteria. These bacteria have been specifically selected because of their enhanced ability to metabolize, eat, typical compounds found in oil water separators such as; oil, diesel, gasoline, BTEX, TPH, and phenols.
