KLOZUR®SP is a powerful chemical oxidant effective in treating a wide range of recalcitrant contaminants, including chlorinated solvents, petroleum and polycyclic aromatic hydrocarbons (PAHs). When activated, it provides an unmatched combination of oxidative power and control that can be delivered both safely and cost effectively. 


KLOZUR®ONE is an all-in-one product containing KLOZUR®SP and activator reagents to deliver activated persulfate chemistry in a single injection more conveniently than ever before. 


KLOZUR®KP is an extended release, environmental grade potassium persulfate with the same power of sodium persulfate but a much lower solubility, making it effective for PRB applications, plume treatment or low permeability zones. 


KLOZUR®CR is an easy-to-use product consisting of alkaline activated KLOZUR®SP and PERMEOX®ULTRA combining the powerful chemical oxidation reactions with long term bioremediation.



EHC®REAGENT is a combination of controlled release organic carbon and micro-scale zero valent iron (ZVI), stimulating both abiotic and biotic dechlorination mechanisms for the treatment of groundwater and saturated soil impacted by chlorinated solvents, pesticides and organic explosives. Also available as EHC®PLUS including powdered activated carbon (PAC) for plume retardation.


ELS®MICROEMULSION is a lecithin-based substrate providing enhanced reductive dechlorination reactions for effective biodegradation of halogenated compounds. 


DARAMEND® REAGENT is a low cost treatment technology for soils impacted by recalcitrant organic compounds, such as chlorinated solvents, pesticides and explosives. 



TERRAMEND®REAGENT is a cost-effective treatment technology for soils impacted by recalcitrant organic compounds that can often be applied without excavation, generates no odors or leachate and does not result in soil bulking. 


PERMEOX®ULTRA is a specially formulated grade of calcium peroxide engineered to provide an extended oxygen release and essential nutrients for enhanced aerobic bioremediation. 



GEOFORM®REAGENTS is the next generation reductive technology, engineered to deliver the building blocks needed to promote in situ biogeochemical reactions. GEOFORM® provides a source of sulfate, ferrous iron, electron donors, pH buffer and nutrients to promote mechanisms for dehalogenation via enhanced anaerobic bioremediation, abiotic degradation and the formation of reactive minerals. 



METAFIX®REAGENTS are custom formulated blends of ZVI, reducing agents, reactive minerals, adsorbents and pH modifiers for treatment of soil or groundwater via formation of stable heavy metal precipitates.
