Petrox Micorbes Remove Naphthalene and other SVOCs Naphthalene is often a recalcitrant petroleum compound that keeps sites from clean closure. This resistance to remediation is due to naphthalene’s relative high adsorption and low solubility rates. Naphthalene has an aqueous solubility of 3.1E1 mg/l compared to benzene at 1.75E3 mg/l . Naphthalene has an affinity of […]
With Petrox microbes, in situ TPH bioremediation reduced the concentration of petroleum in soil at a former gas station from 9,500 mg/kg to 52 mg/kg. The impacted soil was at more than 20 feet deep. Injection of calcium peroxide provided the oxygen needed for metabolism of the petroleum by Petrox microbes. The post treatment sampling […]
Petrox bioremediation reduced contamination by more than 99% in less than a year at a Florida gas station. After three underground storage tanks were removed from the location of a convenience store, investigation showed that petroleum contamination was present in small area near the former dispenser island. The vadose-zone contaminated soil was excavation and disposed […]
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 […]
