OxyTek Chemical Oxidation...

OxyTek is a dynamic new patent pending peroxidant product. The controlled process safely remediates hydrocarbons, chlorinated solvents, herbicides / pesticides, dioxins and PCBs in soil and groundwater both in-situ and ex-situ.

Oxidized contaminates are then mineralized by the biocatalyst integrated into remedial process that leverages the population of contaminant eating bio-organisms. The site is then free of pollutants and requires no further remediation.

The OxyTek Process

The OxyTek process occurs in three steps: Application, Oxidation and Bioremediation, all in one product. The process is a fully integrated biological / oxidation mechanism. The process destroys organic contaminates at a neutral pH at ambient temperature in a short period of time, cost effectively.

Step 1: Application (In-Situ Injection or Ex-Situ Mixing)

In-Situ Applications: The in-situ injection method consists of installing injection wells, constructed of PVC risers and screens, which act as the transport medium for the OxyTekTM product to the subsurface. Each well is fitted for direct injection. The OxyTek product is stored on project sites in polyethylene drums or for larger projects, in tankers. A conventional chemical pump is generally used to inject the wells under moderate pressure to deliver the OxyTek product to the contaminate plume.

Fracturing Applications: In tight soil conditions (silty clay and clayey silt soils) communications between the OxyTek product and adjacent soils can be problematic. For such conditions, injection of the OxyTek is handled by fracturing, a process developed by FracRite Environmental Ltd. (see photograph to left)

Ex-Situ Applications: The ex-situ application of the OxyTek is handled using a conventional backhoe, excavator or other soil handling equipment. The OxyTek product is manually discharged onto the ex-situ contaminated soil and physically bended using the soil handling equipment.

Step 2: Chemical Oxidation

The OxyTek process is the next generation of chemical oxidation. Its optimum performance is a neutral pH range (6.5 to 7.5) and with minimal heat generated (< 4oF). OxyTek process utilizes a Fenton-like oxidation chemistry without the off-gases and soil damage. The controlled oxidation of OxyTek generates oxygenated organic molecules such as alcohols which aid in the desorption of contaminates from soil. This process greatly aids the oxidation process by bringing the contaminates into solution. Finally, these molecules are very prone to degradation by the supplied biological consortium in the product to complete the remediation process. OxyTek produccts are particularly effective for treating high contamination concentrations in saturated and unsaturated zones. Chlorinated compounds are particularly vulnerable to halogen / hydroxyl substitution reactions of this process and no vinyl chloride is produced. Because many biorefractory pollutants such as BTEX, chlorinated solvents, pesticides, fungicides, etc., are fragmented and converted to oxygenated compounds during the oxidation phase, bioremediation of these materials occurs very quickly.

There are no safety issues with the OxyTek process because the reactions are controlled to avoid excessive heat, off-gassing and pH changes. The process is hydrogen peroxide based. If you get some product on your skin, it can be simply washed off with water with no immediate or long term detrimental effects.

Step 3: Bioremediation

During the oxidation phase of the process, any product not consumed as a chemical oxidizer is converted to molecular oxygen. When combined with the bio-nutrient compounds used in the oxidation phase to control the oxidation reaction, bioremediation finishes the job!  The OxyTek process is cost effective, maintenance free and quick!
