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 […]
Petrox microbes were added to excavated petroleum-contaminated soil to accelerate the degradation of DRO and ERO total petroleum hydrocarbons. Petrox was added by spraying the surface of the soil with a hydrated Petrox solution. The microbes were mixed into the soil using a tractor-mounted disc tiller. After approximately […]
Bioaugmentation results can be accelerated and amplified by soil mixing to improve distribution and contact. The equipment shown in this example was used to blend Petrox with contaminated soil to a depth of 10 feet. Click here to view a short video of soil mixing.
