Ivey-Sol Surfactant Techonology

During in-situ and ex-situ remediation of contaminated soil or water the greatest limiting factor for all forms of remediation is contaminant sorption (i.e., absorption and or adsorption). If we can overcome contaminant sorption, we can significantly improve all forms of soil and water remediation, reducing the treatment costs and duration.

Ivey-sol® Surfactant Technology is comprised of several patented and preparatory non-ionic surfactant formulations that have the unique ability to selectively desorb and liberate sorbed (i.e., absorbed and adsorbed) petroleum hydrocarbons (LNAPL), chlorinated solvents (DNAPL), and certain heavy metal contaminants from soil and fractured bedrock surfaces. The addition of Iveysol ® to the substrate can aid in the controlled de-sorption of the contaminants making them more‘Available’ for treatment. Ivey-sol® makes the contaminants more miscible in the aqueous phase allowing for their improved mass recovery and/or improved treatment by many other remediation techniques. Three Ivey-sol® application processes were developed for enhancing in-situ and exsitu site remediation. They are as follows: SER® Surfactant Enhanced Remediation. In-situ and ex-situ application processes to liberate contaminants making them more ‘Hydraulically-Available’ for mass removal and/or treatment.

SER® improves in-situ pump and treatment, and/or ex-situ soil washing type applications by>400%. This process could also be used for tank cleaning, vapour suppression, and oil recovery from oil sands.

SEB® Surfactant Enhanced Bioremediation. In-situ and ex-situ application processes to liberate contaminants making them more ‘Bio-Available’ for microbial (bacteria) degradation. SEB® improves both in-situ and or ex-situ bioremediation treatment by > 60%. Applicable for both warm and cold temperature/climate site applications.

SEO® Surfactant Enhanced Oxidation. In-situ and ex-situ application processes to liberate contaminants making them more ‘Chemically-Available’ for chemical oxidation by chemical oxidizing agents. SEO® improves the availability of the contaminants to the chemical oxidants commonly employed to affect in-situ and or ex-situ chemical oxidation by 40 to 80% or more. The oxidation of non-target compounds (i.e., metals, natural products, and bacteria) is the greatest drawback to chemical oxidant treatment. Ivey-sol® helps overcome this limitation by increasing contact between contaminants and oxidants improving the oxidation rate of target compounds.
This process may also be modified for application with chemical reducing agents.

The sorption of contaminates onto solids (soil, sediments, bedrock, drilling cuttings, oil sands) is considered the principal limiting factor in the effectiveness of most treatment technologies. This coupled with complex chemistry, geology and hydrogeology only further complicates matters.

When HOC (hydrophobic organic compounds) like petroleum product, are absorbed on a soil grain, water alone will not remove it from the surface. This is a function of the hydrophobic characteristics of the HOC, which repels the water at its surface and its inherent low water solubility. With the addition of Ivey-sol® surfactants, the Ivey-sol® hydrophobic grouping is repelled by the water but attracted to the HOC on the surface. At the same time, the Ivey-sol® hydrophilic grouping is attracted to the water molecules. These opposing forces loosen the HOC from the surface of the soil matrix and suspend it in the water phase. Once dissolved, the suspended HOC is more ‘hydraulically-available’ for P&T, more ‘bio-available’ to the microbial population present,
and more ‘chemically-available’ for oxidation. Once liberated in low concentration in a ‘surfactant-aqueous HOC’ microscopic outward appearance, it is more ‘available’ for treatment by most of not all forms of remediation treatment technologies.

Surfactant enhanced remediation involves the use of surfactant formulations to selectively desorb and dissolve target contaminates from the solid to liquid phase. In addition, the surfactants lower the surface tension of water from 72 dynes to <30 dynes increasing the wetting and permeability properties of water in fine grain soil (i.e., clay and silt) and bedrock fractures. The surfactants affect the sorption of HOC at the solid-liquid interface (i.e., the surface–H2O–NAPL interface). As a result, the surfactants increase the contaminate solubility and improved ‘availability’ for rapid and cost effective treatment.

Company Profile

Ivey International Inc. is an award winning environmental technology company with a commitment to provide outstanding products and services through the development and application of innovative air, soil and groundwater remediation technology. Ivey specializes in remediation technology development and provision to environmental consultants, environmental contractors
and oil and gas companies to restore air, soil and water quality.

Absorption and/or adsorption (sorption) of contamination to soils/solids is the #1 reason most forms of remediation are slow, costly and/or fail. Ivey International Inc. has developed the Iveysol ® Remediation Technology to overcome this limitation. As a result, we are able to clean up contaminated soil, water, solids and/or oil and gas wastes more rapidly and economically.

The Ivey-sol® Surfactant Remediation Technology can selectively desorb contamination, including: petroleum hydrocarbon, chlorinated solvent and heavy metals. In doing so, Ivey-sol® liberates these sorbed contaminants from solid substrates making them more “Hydraulically Available” for extraction by pump and treatment (P&T), more “Biologically Available” for bioremediation (In-situ and Ex-situ), and more “Chemically Available” for elimination by chemical oxidation or chemical reduction. Ivey-sol case studies and client references are available upon request.

Ivey-sol® has several commercial and industrial applications including: soil and groundwater remediation, bioremediation, tank cleaning, vapour suppression, NORMs treatment, frac-sand treatment, and marine oil-spill clean-up, among many others.

On average, greater than 90-95% of small to medium size contaminated sites are remediated (Insitu) in less than 12 months. While our Ex-situ process can take just hours or weeks depending on the Ivey-sol® treatment method and contaminants treated.

The Ivey-sol® products and processes have established a strong international reputation for rapid site remediation and reclamation, with significant time and cost savings for our project partners and clients. Our corporate mission is to be “Today’s Environmental Solutions For A Better Tomorrow”.
