For Immediate Release
SGW Services Issued Provect-OX Patent
Chicago, Illinois (PRLog) – November 4, 2021
Provectus Environmental Products, Inc., announces that the Federal Republic of Brazil recently issued Patent No. 1120150283179 (PCT/US2014/036642) to SGW Services, describing the combined use of ferric oxide (or other tri-valent metals) plus persulfate to yield safer, more effective remedial actions.
In 2014, Provectus debuted Provect-OX® as the industry's first self-activated, persulfate-based in situ chemical oxidation (ISCO) amendment specifically designed to support sustained bioremediation processes and therefore minimize rebound (US patent 9,126,245). In 2017, we improved the amendment by adding Terr-OR™ as a buffer and stabilizer for reactive ferrate (patents pending). To date, we have safely and effectively implemented the technology around the globe using a series of preferred (injection) contractors to remediate sites in a single application, without rebound.
When persulfate-based ISCO alternatives are comparatively analyzed, Provect-OX® amendments maintain their leadership in terms of:
Safety
Fewer health and safety concerns compared to traditional activation methods such as hydrogen peroxide or pH extremes using NaOH. 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.
Increased Effectiveness
Promotes multiple oxidation reactions yielding more extensive in situ oxidation of a wider-range of organic contaminants.
Cost Efficiency
Significantly lower costs due to utilization of multiple oxidation reactions with combined secondary treatment processes.
Improved Performance
Will not mobilize heavy metals or cause the generation of secondary impact issues resulting from grossly elevated pH.
Longevity
Uniquely supports long-term, sustained, secondary bioremediation processes. Iron and sulfate will remain in place and active for many years.
Provect-OX® has been successfully used in North America, South America, Oceania, and EAMA. Numerous examples of these projects, along with lessons learned, can be found by visiting the Provect-OX technology page.
Provect-OX® Technology
An all-in-one sodium persulfate blend activated with ferric iron for efficient, safer ISCO treatment.
