KLOZUR® SP

KLOZUR®SP is the oxidant of choice for in situ chemical oxidation (ISCO), because of its proven ability to treat a wide range of contaminants including chlorinated solvents, petroleum and PAHs. Based upon an environmental grade of sodium persulfate (SP), KLOZUR®SP is ideal for contaminated source zones and hot spots that require rapid treatment. When properly activated, KLOZUR®SP provides an unmatched combination of oxidative power, versatility, and control that can be delivered both safely and cost effectively. Successful field applications of KLOZUR® activated persulfate have been performed globally. These applications demonstrate the ability of KLOZUR® activated persulfate to treat diverse organic contaminants of concern including: chlorinated ethenes (TCE, PCE, DCE and vinyl chloride), chlorinated ethanes (TCA and DCA), chlorinated methanes (carbon tetrachloride and methylene chloride), BTEX, MTBE, polyaromatic hydrocarbons (PAHs), petroleum hydrocarbons (TPHs, GRO, DRO), 1,4-dioxane and pesticides.
THE SOUND SCIENCE OF KLOZUR®ACTIVATED PERSULFATE
KLOZUR® activated persulfate has a long history of documented success having been used at thousands of sites to remediate contaminants of concern around the world. The field application of KLOZUR® activated persulfate has been scientifically validated in hundreds of independent peerreviewed journal articles and conference presentations.

Benefits at a glance

When used with Evonik’s patented activation methods, KLOZUR® SP produces the powerful oxidative (SO4-•, OH•) and reductive (O2-•) radicals creating a multi-radical attack for the rapid destruction of recalcitrant compounds.
S₂O₈-2 + Activator → SO₄- •, OH•, O₂- •
Multiple activation options and methods of delivery provide for a flexible and custom solution based on site conditions. With a solubility limit of up to 40 wt%, KLOZUR®SP can be applied as a fully soluble solution. KLOZUR® SP is a stable oxidant given its high oxidation potential, with a typical active lifetime in the subsurface of weeks to months, providing an extended radius of influence.
