HYDROCARBON CONTAMINATED FILTER CAKE

Biological Treatment Summary

The Situation

Bio-Form LLC conducted a pilot test for a petroleum service company. Historically, the processed filter cake solids were accumulated in poly bags and transported to a hazardous waste landfill. The purpose of the pilot test was to remediate the solids so that they could be disposed of as non-hazardous waste, thus creating substantial savings to the petroleum service company and their clients.

The Solution

Bio-Form LLC recommended treating the filter cake during the final wash cycle with OBT®. In addition, the solids were treated as they accumulated into the receiving bin.

The Results

TPH levels in the filter cake material prior to treatment were in excess of 118,000 mg/kg. After the first two weeks of treatment, the levels had dropped to 815 mg/kg. At the end of the test (three weeks) the levels had dropped below 100 mg/kg.

mg/kg = ppm (parts per million)

TPH = Total Petroleum Hydrocarbons (EPA Method 1664 or EPA Method 8015M)
