Biotechnology of hydrocarbon bioremediation in soil washing slurry
Application of Bioremediation for low cost contaminated soil washing slurry treatment with quick hydrocarbon reduction and improved sustainability. The application uses proprietary microbial formulation with a slurry bioreactor in order to accelerate the degradation process and to make it compatible with soil washing technology. The end result is a treated soil which meets the requirements for ...

Thermal Desorption
Untitled Document Introduction: Thermal desorption is a physical separation process and is not designed to destroy organics. Wastes are heated to volatilize water and organic contaminants. A carrier gas or vacuum system transports volatilized water and organics to the gas treatment system. The bed temperatures and residence times designed into these systems will volatilize ...

The METS Process in Brief/2019
The METS remediation process equipment is about the size of a large SUV. It is fully mobile and self-propelled. Previously excavated soil is deposited in the hopper at the top of the apparatus by a conventional front-end loader. Very large debris, such as rock, concrete or asphalt, is usually screened off at the hopper opening. From the hopper, the soil is transferred in a regulated flow to a ...

Improving the Predictability of Petroleum Brownfield Restoration
It’s no secret that the United States has an aging infrastructure problem. The public’s attention is focused on the repair of roadways and bridges, but there is also an ongoing initiative to address the existing infrastructure of legacy underground storage tanks, abandoned gas stations and truck stops, that are designated petroleum brownfields. As of July 2021, approximately 21 ...

Remediation of silty-clay hydrocarbon contaminated site using Ivey-sol selective phase transfer technology
Earlier this year, Ivey International Inc. secured its first remediation project in Alberta using its Ivey-sol Selective Phase Transfer Technology (SPTT). This patented technology is being used to treat extensive soil and groundwater contamination at an active service station in Red Deer, Alberta. With a residential area nearby, the environmental sensitivity is relatively high. Unfortunately, ...

Ivey-Sol Technology has potential to increase oil recovery of oil-sands waste by 15-25 percent
Alberta’s oil sands are comprised of one of the world's largest sources of bitumen, containing an estimated 1.6 trillion barrels. About two tonnes of oil sands must be dug up and processed to produce one barrel of oil. Oil sands recovery processes include extraction and separation systems to remove bitumen from sand and water. Separating the oil from the sand is difficult and costly, and getting ...

Remediating Soil While Preserving Soil Structure
The importance of soil cannot be overstated. It’s the basis of agriculture, and as a result, is a critical component of sustaining human life. According to the EPA: “Productive soils, a favorable climate, and clean and abundant water resources are all essential for growing crops, raising livestock, and for ecosystems to continue to provide the critical provisioning services that ...

A Citizen`s Guide to Bioremediation
What is bioremediation? Bioremediation is a treatment process that uses naturally occurring microorganisms (yeast, fungi, or bacteria) to break down, or degrade, hazardous substances into less toxic or nontoxic substances. Microorganisms, just like humans, eat and digest organic substances for nutrients and energy. In chemical terms, 'organic' compounds are those that contain carbon and hydrogen ...
