Ivey-sol Remediation Information

REMEDIATION SOLUTIONPROCESS DESCRIPTIONDuring in-situ and ex-situ remediation of contaminated soil or water the greatest limiting factor forall forms of remediation is contaminant sorption (i.e., absorption and or adsorption). If we canovercome contaminant sorption, we can significantly improve all forms of soil and waterremediation, reducing the treatment costs and duration.Ivey-sol® Surfactant Technology is comprised of several patented and preparatory non-ionicsurfactant formulations that have the unique ability to selectively desorb and liberate sorbed (i.e.,absorbed and adsorbed) petroleum hydrocarbons (LNAPL), chlorinated solvents (DNAPL), andcertain heavy metal contaminants from soil and fractured bedrock surfaces. The addition of Ivey-sol® 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 phaseallowing for their improved mass recovery and/or improved treatment by many other remediationtechniques. Three Ivey-sol® application processes were developed for enhancing in-situ and ex-situ air, soil and groundwater site remediation. They are as follows:SER® Surfactant Enhanced Remediation. In-situ and ex-situ application processes to liberatecontaminants 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%. Thisprocess could also be used for tank cleaning, vapour suppression, and oil recovery from oil sandsor oil shales.SEB® Surfactant Enhanced Bioremediation. In-situ and ex-situ application processes to liberatecontaminants making them more ‘bio-available’ for microbial (bacteria) degradation. SEB®improves both in-situ and/or ex-situ bioremediation treatment by 40 to 60% or more. Applicable forboth warm and cold temperature/climate site applications.SEO® Surfactant Enhanced Oxidation. In-situ and ex-situ application processes to liberatecontaminants making them more ‘chemically-available’ for chemical oxidation by chemicaloxidizing agents. SEO® improves the availability of the contaminants to the chemical oxidantscommonly employed to affect in-situ and or ex-situ chemical oxidation by 40 to 80% or more. Theoxidation of non-target compounds (i.e., metals, natural products, and bacteria) is the greatestdrawback to chemical oxidant treatment. Ivey-sol® helps overcome this limitation by increasingcontact between contaminants and oxidants improving ounds.This process may also be modified for application with ductivedechlorination.Ivey-sol®Surfactant TechnologySER®, SEB®, and SEO®the oxidation rate of target compchemical reducing agents in reAPPLICATIONSThe sorption of contaminates onto solids (i.e., soil, sediments, bedrock, sludge, drilling cuttings,oil sands and oil shales) is considered the principal limiting factor in the effectiveness of mosttreatment technologies. This coupled with complex chemistry, geology and hydrogeology onlyfurther complicates matters.When HOC (hydrophobic organic compounds) like petroleum product, are absorbed on a soilgrain, water alone will not remove it from the surface. This is a function of the hydrophobiccharacteristics of the HOC, which repels the water at its surface and its inherent low watersolubility. With the addition of Ivey-sol® surfactants, the Ivey-sol® hydrophobic grouping is repelledby the water but attracted to the HOC on the surface. At the same time, the Ivey-sol® hydrophilicgrouping is attracted to the water molecules. These opposing forces loosen the HOC from thesurface of the soil matrix and suspend it in the water phase. Once dissolved, the suspended HOCis more ‘hydraulically-available’ for Pump and Treatment (P&T), more ‘bio-available’ to themicrobial population present, and more ‘chemically-available’ for oxidation or reduction reactions.Once liberated in low concentration in a ‘surfactant-aqueous HOC’ microscopic outwardappearance, it is more ‘available’ for treatment by most, if not all, forms of in-situ and ex-situremediation treatment technologies.Surfactant enhanced remediation involves the use of surfactant formulations to selectively desorband dissolve target contaminates from the solid to liquid phase. In addition, the surfactants lowerthe surface tension of water from 72 dynes to <30 dynes increasing the wetting and permeabilityproperties of water in fine grain soil (i.e., clay and silt) and bedrock fractures. The surfactantsaffect the sorption of HOC at the solid-liquid interface (i.e., the surface–H2O–NAPL interface). Asa result, the surfactants increase the contaminate miscibility and improved ‘availability’ for rapidand cost effective treatment.Market Applications (General): Petroleum (Oil & Gas) Industry, Chemical and Petrochemical,Utility and Energy, Commercial and Industrial Manufacturing, Government, Real EstateDevelopment, Industrial Cleaning, Free Product Removal and Green Technology and SustainableEnvironmental Initiatives etc.Market Applications (Specific): Air, Soil and Water Remediation, Oil Recovery (Oil Sands),Tank Cleaning, Bioremediation (In-situ and Ex-situ), Waste Water Treatment, Pump andTreatment, Improving Chemical Oxidation, Off-shore Spill Dispersant, Shoreline Clean-up, VapourSuppression, Soil Washing, Degreaser, Biodegradable Solvent/Cleaner, etc.MechanismIvey-sol® shown desorbing contamination off a surface.

Ivey International Inc.specializes in remediation technology development and provision to environmental consultants,environmental contractors and oil and gas companies.Sorption (absorption and/or adsorption) of contamination to soil, bedrock and/or solid waste is the#1 reason most forms of remediation are slow, costly and/or fail. Ivey International Inc. hasdeveloped the Ivey-sol® Remediation Technology to overcome this limitation. As a result, we areable to clean up contaminated soil, bedrock, solid waste, water, groundwater and oil and gaswastes more rapidly and economically.The Ivey-sol® Surfactant Remediation Technology can selectively desorb contamination,including: petroleum hydrocarbons, chlorinated solvents and heavy metals. In doing so, Ivey-sol®liberates these sorbed contaminants from solid substrates making them more ‘hydraulicallyavailable’ for extraction by pump and treatment (P&T), more ‘biologically available’ forbioremediation (in-situ and ex-situ), and more ‘chemically available’ for elimination by chemicaloxidation or chemical reduction. Ivey-sol® case studies and client references are available uponrequest.Ivey-sol® has several commercial and industrial applications including: soil and groundwaterremediation, bioremediation, tank cleaning, vapour suppression, NORMs treatment, frac-sandtreatment, and marine oil-spill clean-up, among other applications.On average, greater than 90 to 95% of small to medium size contaminated sites are remediated(In-situ) in less than 12 months.
