Off-Shore and On-Shore Spill Remediation Munox SR has been approved by the USEPA for emergency use for marine and other oil spills. The listing is based on independent verification of effectiveness and absence of toxic substances or pathogens. The USEPA tested the degradation rate of oil using Munox SR for NCP listing. The degradation rate […]
Adding Nutrients Increases Long-Term Population and Bioremediation Results The goal of bioaugmentation is to improve the rate of contaminant removal by adding a high population of beneficial microbes to the contaminated media. The additional microbes should provide short-term benefit as the microbes begin metabolizing the contaminants immediately upon injection. But what benefit does bioaugmentation provide […]
Recent data from field applications of Petrox bioremediation show degradation rates of 100 to 500 micrograms per liter (ug/ml) per day. These degradation rates are for total petroleum hydrocarbons or total BTEX, depending on the site monitoring requirements. Achieving high degradation rates requires high initial concentrations. Initial concentrations of 1,000 to 10,000 ug/l were used […]
Using a special microbial blend, Delta Environmental has been successfully bioremediating high concentrations of heavy oil in soil around pipelines and oil production equipment. At a typical site, Delta reduced the concentration of petroleum C34 to >C50 from 130,000 mg/Kg to less than 10,900 in 30 days. That is a removal rate of 3,970 mg/Kg/day. […]
Sulfolane is an emerging contaminant of concern for potential environmental impact to ground water in Alberta. CL Solutions recently completed laboratory bench-scale testing that showed the Petrox organisms can efficiently degrade sulfolane. Under laboratory conditions Petrox organisms metabolized sulfolane at a minimum rate of 33 ug/L/day. Further lab tests are under way and field scale […]
