OxyTek-ADT Metal Stabilization...
AdvantagesStandard stabilization techniques “encapsulate” or bind heavy metals to contaminated media by adding cement with pozzolonic materials. This approach adds to both volume and mass of the treated material, is difficult to apply, costs more, and has uncertain longevity. The approach involves converting the physical state of the leachable metallic and oxide forms to environmentally stable mineral and other chemical forms without adding to volume or mass, and avoiding or minimizing offsite disposal costs. The technique typically results in a cost-savings of 30 to 60% over conventional techniques and treatment results are permanent. Heavy Metal SolutionsOxyTek-ADT heavy metal treatment technology centers on a unique array of chemical reagents together with a body of remedial knowledge and experience that significantly reduces the toxicity (TCLP) of heavy metals in soil, sludge, sediment or groundwater. Federal regulation requires the removal and proper disposal of heavy metal wastes exceeding EPA/Environment Canada’s minimum clean up standards. Proprietary treatment methods render regulated levels of lead, chrome, cadmium, arsenic and other heavy metals permanently into a non-leachable, safer form, suitable for leaving on site or taken off site as non-hazardous (RCRA) waste. OxyTek-ADT technology utilizes a range of different chemical reagents specific to the type of contaminants combined with years of heavy metal remedial experience to produce a highly effective and permanent solution for even the most complex environmental problems. Our technology has a number of distinct advantages in terms of versatility of use, means of application, and economic benefit. These include effective TCLP reduction of one or more heavy metals, little or no increase in treated waste volumes, and flexibility in application. It provides a viable alternative to hazardous waste disposal. Ultimately, all heavy metal wastes exceeding strict EPA / Environment Canada environmental standards require adequate toxicity reduction and proper disposal. Custom Designed TreatmentOver 4.3 millions tons of reportable metal contaminated process wastes are generated in the States and Canada each year. Waste generated at each site is unique having different physical and toxic characteristics. and there is no single treatment process or method to address every waste or site situation. OxyTek-ADT customizes treatment methods for each unique situation, and our versatile process allows multiple TCLP metals (i.e. lead, chrome and arsenic) to be reduced simultaneously. OxyTek-ADT custom designed heavy metal treatment also provides the highest level of assurance in terms of heavy metal reduction consistency and longevity. OxyTek-ADT technology does not promote any one specific reagent or treatment method but produces the right combination of reagent. Waste Treatment Streams

Applications for every situation - in situ application at remote locations for both small and large scale sites - projects where off site transportation and disposal may be cost prohibited or impractical. - environmentally sensitive sites and ecosystems requiring minimal disruption - custom treatment formulations can be applied in a liquid or solid state through highly controlled spraying, mixing, or injection - simple physical contact with metal contaminates is all that is required to produce immediate TCLP reduction - ex-situ application using conventional excavators, backhoes or other soil moving equipment - in-situ application using the OxyTekTM Injection System The end result is a non-leaching metal bearing waste stream with the treatment process having no negative health or environmental impacts. The ability to treat three heavy metal contaminates on location or within existing waste treatment processes in a non-intrusive manner is another reason why OxyTekTM-ADT treatment methods offer a viable option in solving waste management issues. Given the wide range of application options, OxyTek-ADT treatment are not restricted by site conditions or industrial processes that would normally preclude other on site treatment or remedial methods.
OxyTek-ADT treatment advantages:- rapid mobilization and demobilization - minimal interference to ongoing production or operations - minimum space requirements - single event or phased project approach
