Klozur® SP is the oxidant of choice for in situ chemical oxidation (ISCO), because of its ability to treat a wide range of contaminants. When properly activated, Klozur SP provides an unmatched combination of oxidative power and control that can be delivered both safely and cost effectively.
Peroxygen Talks is a series of web-based white papers on topics regarding the use of in situ chemical oxidation (ISCO) for soil and groundwater. They cover a variety of technical topics relevant to ISCO, such as persulfate activation methods, treatment of emerging contaminants, fate of residual sulfate, interaction of ISCO with microbial populations and impacts on groundwater quality.
