Oil sludge (over 25 years old) from a drilling waste holding pond was provided to BioWorld for bench scale testing to demonstrate the feasibility of BioWorld Bioremediation Technology. The initial Total Petroleum Hydrocarbon (TPH) concentration of the sludge was 76,000 ppm. Samples designated untreated and treated were placed in separate glass aquariums with the same amount of distilled water in each aquarium. BioWorld bioenhancement and augmentation technology consisting of Liquid Optimizer and Hydrocarbon Digesting Microbes were added several times to the treated sludge aquarium. After three months, the water from each aquarium was allowed to evaporate, leaving a solid material behind. Chemical analysis of the untreated and treated sludge samples indicated TPH concentrations of 75,000 ppm and 31,000 ppm, respectively. This corresponds to a 60% reduction in TPH concentration using BioWorld Bioremediation Technology.

A tractor repair facility uses a 600-gallon recirculating oil/water separator and steam cleaner system to pressure wash tractors. Oily waste water determined to be hazardous collects in the separator system. BioWorld Liquid Optimizer and Hydrocarbon Digesting Microbes were added to treat the oil. After three days, breakdown and digestion of the petroleum hydrocarbons was apparent. On-going weekly treatments continued to digest the oily waste into non-hazardous substances.

Project Summary #812 (Mixed Transportation Waste)

A tank transport facility generates wastewater containing mixed vegetable oil and petroleum hydrocarbons. The wastewater collects in a concrete-lined pit. BioWorld Liquid Optimizer, Hydrocarbon Digesting Microbes and General Blend Microbes were added several times to treat the mixed waste. Digestion of the mixed waste was apparent and a reduction in TPH and Oil & Grease concentrations was verified.
