PersulfOx™, a New Catalyzed-Persulfate Technology for Groundwater and Soil Remediation

REGENESIS recently announced PersulfOx™ Catalyzed Persulfate. This new environmental technology is a patented, sodium persulfate-based in situchemical oxidation (ISCO) reagent designed specifically for groundwater and soil remediation at contaminated sites, including brownfields.

PersulfOx™, a New Catalyzed-Persulfate Technology for Groundwater and Soil Remediation

Traditionally, sodium persulfate has been used and activated with the addition of a separate component such as heat, chelated metals, hydrogen peroxide, or a caustic base. These activation processes are inherently complex, costly and can pose certain health and safety risks. By design, PersulfOx simplifies the activation process and reduces on-site health and safety liability by offering environmental professionals a new, all-in-one reagent with a built-in catalyst. There is no hazardous activation process, and performance is equivalent to the best alternative persulfate treatments available today. In the field, the material is easily mixed with water and applied into the contaminated area using common subsurface injection techniques or soil mixing tools.

Additionally, the PersulfOx catalyst further increases the product’s effectiveness by providing a microscopic heterogeneous surface where the contaminant and oxidant can converge and oxidation reactions can occur repeatedly. This unique and highly efficient “surface-mediated oxidation” process, first introduced in 2007 with RegenOx®, the company’s first ISCO technology, provides several contaminant-reducing benefits, including:

  • Increased efficiency, as it brings oxidant and contaminant together, isolating the oxidation reaction from soil matrix effects,
  • Direct chemical oxidation,
  • The formation of sulfate-based free radicals which in turn oxidize the contaminant, and
  • The formation of ancillary free radicals and other oxidizing species which destroy contaminants within the contaminated matrix.
