Introducing Provect-OX2™ Extended Release, Self-Activating ISCO / Enhanced Bioremediation Reagent

Introducing Provect-OX2 Extended Release, Self-Activating ISCO / Enhanced Bioremediation Reagent

In 2014, Provectus debuted Provect-OX®  as the industry’s first self-activated, persulfate-based ISCO amendment specifically designed to support sustained bioremediation processes and therefore minimize rebound (US patent 9,126,245; patents pending).

In 2017, we improved the amendment by adding Terr-OR as a buffer and stabilizer for reactive ferrate (patents pending).

Today, we are happy to announce our next generation ISCO technology.

Provect-OX2 ™ is a combination of sodium and potassium persulfate plus Terr-OR®  buffer/ferrate stabilizer to allow for extended in situ chemical oxidation (ISCO) uniquely coupled with long-term (> 3 years) enhanced bioremediation. How? Ferric iron (Fe III) is used as a safe and effective means of activating the persulfates (US Patent No. 9,126,245; patents pending). Subsequently, iron and sulfate serve as alternative electron acceptors to drive biodegradation, and myriad iron-sulfate biogeochemical reactions geologically form reactive minerals in situ to help manage COI rebound, long-term.

Bottom line: successful remedial action with One Injection Event. The synergistic chemistries render Provect-OX® and Provect-OX2™ “Much Greater Than One”.


Provect-OX ® technologies offer important benefits not inherent to other ISCO alternatives, and are designed to be the safest, most effective, most cost-efficient choice.   When persulfate-based ISCO alternatives are comparatively analyzed (Click Here), Provect-OX ®  and Provect-OX2­ ™ amendments maintain their leadership in terms of:

Safety: Provect-OX ®  has fewer health and safety concerns as compared to use of traditional activation methods such as heat, chelated metals, hydrogen peroxide or pH extremes using NaOH. Provect-OX ®  will not generate excessive heat/off-gases.

Ease of Use: Single component product – all in one bag – with integrated buffer, ferrate-stabilizer, and activator results in simplified logistics and application.

  • No additional containers or multi-step mixing ratios required during field application
  • Fewer handling logistics and equipment compatibility issues
  • No secondary containment requirements

Increased Effectiveness: Promotes multiple oxidation reactions such as ferrate, superoxide and persulfate-based free radicals yielding more extensive in situ oxidation of a wider-range of organic contaminants. Also provides a unique microbiological component for multiple accelerated attenuation processes that act to minimize or prevent contaminant rebound after oxidation reactions have terminated.

Cost Efficiency: Significantly lower costs due to utilization of multiple oxidants with combined secondary treatment processes. Use of ferric oxide conserves oxidant when compared to organo-iron or chelated iron activation.

Improved Performance: Will not mobilize heavy metals or cause the generation of secondary impact issues such as elevated arsenic or chromium resulting from grossly elevated pH.

Longevity: Uniquely supports long-term ISCO + sustained (3 to >5 years) secondary bioremediation processes to manage residuals and minimize or prevent contaminant rebound as iron will remain in place and active for many years.

Patented Technology: Fully covered US and pending international patent 9,126,245 (other patents pending) that indemnify you and your client from patent infringement.

Safer, More Effective ISCO using Non-Extreme Persulfate Activation that Yields Sustained, Secondary Biotreatment.

Provect-OX® has been successfully used in North America, South America, Oceania and EAMA. Various examples of these projects, along with lessons learned, can be found on our website.
