In situ Heavy Oil Bioremediation in Alberta
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. This approach not only benefits the environment ...

Improve Soil Flushing and LNAPL Removal with Petrox EC
Petrox EC is a product that combines a surfactant with petroleum-degrading microbes to improve separate phase oil recovery and bioremediation of residual oil. The combined approach improves the rate of oil removal from soil and other subsurface media and establishes a beneficial petroleum-degrading microbial population that will treat tightly bound or deeply penetrated oil. Petrox EC has been ...

Petrol and heating oil bioremediation using EU70 (case study)
As a result of an accident a tanker lost its load of petrol and heating fuel. A large quantity of fuel approximately 2000 litres soaked into the soil. Analyses revealed that the average level of hydrocarbons present was in the order of 0.55 %. The pollution affected an area of 100 m2 and to a depth of 0.6 m. Our goal was to reduce hydrocarbon levels to the lowest possible value in order to meet ...

Surface Oil Spill Bioremediation
Petrox microbes provide quick response surface oil spill bioremediation. Petrox can be applied to the oil surface with a backpack sprayer to initiate rapid bioremediation. This approach protects surface water and vegetation with minimal surface traffic. In the following example, an oil spill affected the vegetation and surface water at the edge of a lake. Contractors applied Petrox to the oil ...

Bioremediation techniques, category definitions, and mode of action in marine and freshwater environments
The purpose of this article is to update and supplement the National Response Team (NRT) Science and Technology Committee's Bioremediation in Oil Spill Response Fact Sheet published in May 2000 and RRT guidance documents issued for FOSCs and response professionals. Although existing US NRT and RRT guidance covers important facts about bioremediation, existing material does not adequately define ...

Petrox Bioremediation of Oil Pipeline Leak
Petrox bioremediation was used to treat unrefined oil that leaked from a pipeline in Texas. The oil migrated from the impacted soil into ground water and seeped into the surface water in a nearby river. After one application of Petrox, the oil concentrations in ground water at the source decreased from 600ppm to less than 100 ppm. Two more treatments reduced the petroleum concentration to less ...

Prevent Stagnation Zones during Injection to Improve Contact Efficiency
When injecting into multiple wells simultaneously, stagnation zones can develop preventing effective reagent delivery. Figure 1 shows the simulated EOS Pro distribution in a homogeneous aquifer when EOS Pro is injected into all the wells in a biobarrier at the same time. Simultaneous injection creates gaps in the biobarrier where converging streamlines prevent effective distribution. ...

Response surface analysis and modeling of n-alkanes removal through bioremediation of weathered crude oil
Central composite design (CCD) and response surface methodology (RSM) were employed to optimize four important variables, i.e. amounts of oil, bacterial inoculum, nitrogen and phosphorus, for the removal of selected n-alkanes during bioremediation of weathered crude oil in coastal sediments using laboratory bioreactors over a 60 day experimentation period. The reactors contained 1 kg soil with ...

Bioremediation of Oil-Contaminated Soil in Kazakhstan - Case Study
Project Description The project consisted of the bioremediation of soil contaminated with mineral oils and approximately 3% crude oil. The soil matrix consisted of a fine grain composition with high salt contents. Therefore, a special bioremediation process employing static regeneration had been developed. The remediation procedure also included the sensor assisted addition of air and steam ...

Impact of heavy metals on the oil products biodegradation process
Oil products continue to be used as a principal source of energy. Wide-scale production, transport, global use and disposal of petroleum have made them major contaminants in prevalence and quantity in the environment. In accidental spills, actions are taken to remove or remediate or recover the contaminants immediately, especially if they occur in environmentally sensitive areas, for example, in ...

Enhanced bioremediation of crude oil in polluted beach sand by the combination of bioaugmentation and biodiesel
Biodiesel produced from rapeseed oil was used as a cost-effective and sustainable agent to enhance crude oil biodegradation in sand microcosms. The initial concentration of crude oil and total petroleum hydrocarbon (TPH) was 20,000 and 18,750 mg/kg, respectively. The mass ratio of biodiesel to crude oil was 0 (designated T1), 1:10 (designated T2), 1:4 (designated T3), and 1:2 (designated T4). ...

Hydrocarbon Bioremediation – Cleaning fuels & motor oil spills on water - Case Study
Background Nanobite Products proved how effective they are in hydrocarbon bioremediation on water with the almost total remediation in one week of fuel spills from abandoned cars. Read on… On March 30 2006, in Black Sod Bay in County Mayo, between 45 and 50 cars were transported from a neighbouring island destined for scrap. They were deposited at low tide on the shoreline to await ...

Biodegradation of total petroleum hydrocarbon (TPH) in Jordanian petroleum sludge
Bioremediation, or the use of micro-organisms to decontaminate soil or groundwater, is being increasingly seen as an effective, environment-friendly treatment for oil-contaminated sites. In this study, the results are presented concerning a laboratory screening of several natural bacterial consortia and laboratory tests to establish the performance in degradation of hydrocarbons contained in oily ...

What is MEOR?
MEOR is microbial enhanced oil recovery. Some microbes produce biosurfactants that increase the water-solubility of oil. The biosurfactants’ benefit microbes by making it easier for the microbes to metabolize oil. Additionally, the biosurfactants can strip oil from rock and soil surfaces to improve environmental remediation by extraction, air stripping, or sparging. The Pseudomonas ...
