Remediation White Paper: Catalyzed Persulfate Advancing In Situ Chemical Oxidation (ISCO) Technology for Groundwater and Soil Treatment

SAN CLEMENTE, CALIFORNIA, May 23, 2013 — REGENESIS, a leader in the development of advanced environmental remediation technologies, announces a new white paper detailing its recently introduced sodium persulfate-based remediation technology, PersulfOx™. This new advancement in sodium persulfate technology provides cost and time savings to remediation practitioners across the globe with an all-in-one, easy-to-handle, in situ chemical oxidation (ISCO) reagent.

ISCO with sodium persulfate has been widely used since the 1990s as a way to rapidly remove many types of organic contaminants, including both petroleum hydrocarbons and chlorinated solvents, from soil and groundwater. Unfortunately, the most common persulfate ISCO approaches typically require a separate activation step via the use of additional chemical products, such as sodium hydroxide, which are highly exothermic when mixed with water. This added material increases the cost, logistics requirements and safety risk. REGENESIS has significantly advanced persulfate technology with an all-in-one, single component reagent which eliminates the need for a separate chemical activator and employs an advanced catalyst system resulting in equivalent performance and lower health and safety risk.

While PersulfOx is both easier and safer to use than traditional persulfate activation, it has proven highly effective against the most significant types of contaminants, including aliphatic hydrocarbons, BTEX (benzene, toluene, ethylbenzene, xylenes), chlorinated ethenes (e.g. perchloroethene, trichloroethene), chlorinated ethanes (e.g. trichloroethane) and oxygenates (e.g. MTBE, TBA, 1,4,-dioxane). For more information in the form of technical bulletins, product details and a recorded webinar documenting PersulfOx performance from a third party, visit www.persulfox.com.

The 14-page PersulfOx white paper, “Catalyzed Persulfate: Advancing In Situ Chemical Oxidation (ISCO) Technology,” briefly reviews the history of ISCO remediation technologies, including hydrogen peroxide, permanganate, percarbonate and conventional sodium persulfate chemistries and discusses the traditional means of activating persulfate. It then introduces and describes in detail the patented PersulfOx chemistry, which includes information on its unique built-in silica-based catalyst. The white paper is available as a PDF file at www.persulfox.com.
