    PersulfOx® and PersulfOx SP

    Advancing the Science of Activated Persulfate with Built-In Activation, Ease-of-Use and Flexible Formulations

    Benefits:

    PersulfOx®Catalyzed Persulfate

    • Promotes rapid and sustained in situ oxidation of a wide-range of organic contaminants
    • Contains a built-in catalyst that remains active through the entire lifespan of the persulfate oxidation reaction
    • The catalyst also eliminates the need for the co-application of alternate and potentially hazardous activation chemistries
    • Contaminant oxidation performance equivalent to best alternative persulfate activation methods
    • Fewer health and safety concerns than with use of traditional activation methods such as heat, chelated metals, hydrogen peroxide or base
    • Single component product results in simplified logistics and application
    • No additional containers or multi-step mixing ratios required prior to application
    • Compatible with combined remedy approaches including enhanced biodegradation

    PersulfOx SP

    • Promotes rapid and sustained in situ oxidation of a wide-range of organic contaminants
    • Designed specifically for use when a separate chemical activation process such as alkaline activation, hydrogen peroxide activation, or iron activation is required
    • Once the activating chemical is consumed, a level of radical formation is sustained as a result of the PersulfOx catalyst’s persistence
    • Can be used as a follow-on treatment to Regenesis’ PersulfOx Catalyzed Persulfate technology
    • Compatible with combined remedy approaches including enhanced biodegradation

    PersulfOx Catalyzed Persulfate

    Advancing Activated Persulfate Science with Built-In Activation and Ease-of-Use

    PersulfOx is an advanced in situ chemical oxidation (ISCO) reagent that destroys organic contaminants found in groundwater and soil through abiotic chemical oxidation reactions. It is an all-in-one product with a built-in catalyst which activates the sodium persulfate component and generates contaminant-destroying free radicals without the costly and potentially hazardous addition of a separate activator. The patented catalyst enhances the oxidative destruction of both petroleum hydrocarbons and chlorinated contaminants in the subsurface.

    Typically, sodium persulfate is activated with the addition of heat, chelated metals, hydrogen peroxide, or base in order to generate sulfate radicals. These activation processes are inherently complex, costly and can pose additional health and safety risks. In comparison, PersulfOx is a relatively safe and easy-to-use ISCO agent.

    PersulfOx utilizes a unique silica-based, microscopic surface on which oxidants and contaminants can come together and react in a distinct and efficient process known as “surface mediated oxidation.” During this process, oxidation reactions occur repeatedly on the surface of the catalyst serving several contaminant-reducing functions:

    • The generation of sulfate radical and other oxidizing species
    • Accelerated oxidation through the adsorption of contaminant molecules and other oxidizing species
    • Catalyzes direct and free-radical-mediated oxidation by sodium persulfate

Furthermore, through an arrangement between Regenesis and FMC Corporation, PersulfOx customers are free to use PersulfOx without any risk of patent infringement claims from FMC Corporation.

    PersulfOx SP

    For use on Projects Specifying the use of Sodium Persulfate and a Separate Chemical Activator such as Alkaline Activation, Hydrogen Peroxide Activation, or Iron Activation

    PersulfOx SP is part of the PersulfOx line of in situ chemical oxidation reagents which, when used for environmental remediation, is capable of destroying organic contaminants in groundwater and soil through powerful chemical oxidation reactions. PersulfOx SP was formulated for use on projects specifying the use of persulfate and a separate chemical activation process such as alkaline activation, hydrogen peroxide activation, or iron activation. It can also be used as a follow-on treatment to Regenesis’ PersulfOx Catalyzed Persulfate technology.

    When mixed with water PersulfOx SP forms a solution that can be mixed with soil or injected into subsurface groundwater along with a chemical activation technology (i.e. NaOH, hydrogen peroxide, chelated iron, etc.). Upon activation the product produces a suite of powerful oxidizing radicals which destroy a broad range of pollutants. Once the activating chemical is consumed, a level of radical formation is sustained as a result of the PersulfOx catalyst’s persistence.

    Traditional methods of activation are known to be short-lived, requiring multiple reapplications of costly chemical activator. By replacing sodium persulfate with PersulfOx SP, the environmental professional gains all the benefits of traditional activation technologies PLUS the assurance that after the chemical activator is consumed, the catalyst remains behind. The remaining catalyst continues the formation of the desired pollutant destroying oxidation reactions.

    In the event that a remediation program involving PersulfOx Catalyzed Persulfate requires multiple injections of oxidant the practitioner may determine that a full measure of catalyst is not required in which case follow-on applications of PersulfOx SP may be appropriate.
