Advanced ISCO Remediation Solutions
KLOZUR® Persulfate Portfolio
KLOZUR® persulfates, when activated using Evonik’s patented technologies, deliver highly effective in situ chemical oxidation (ISCO) and reduction for environmental remediation. These powerful oxidative and reductive radicals target and break down a broad spectrum of contaminants in soil and groundwater—including chlorinated solvents, petroleum hydrocarbons, and polycyclic aromatic hydrocarbons (PAHs). Our proven patented activated KLOZUR® persulfate portfolio on methods include high pH (alkaline), chelated metals, hydrogen peroxide, heat, and zero valent iron (ZVI), ensuring optimal performance across diverse site conditions.
Advanced ISCO Contaminant Treatment with KLOZUR® Persulfate
Evonik’s proven activation methods for KLOZUR® persulfates include:
- Alkaline activation (high pH)
- Chelated metal compounds
- Hydrogen peroxide
- Thermal activation
- Zero valent iron (ZVI)
These approaches enable customized in situ chemical oxidation (ISCO) for a wide range of remediation needs. Evonik’s patented processes ensure fast, sustainable, and cost-efficient contaminant degradation.
Powerful Radicals for Soil and Groundwater Remediation
Activated KLOZUR® persulfate generates highly reactive radicals with exceptional oxidation strength, capable of breaking down both common and persistent contaminants in soil and groundwater.
Optimized Subsurface Distribution and Long-Lasting Impact
Thanks to its high chemical stability, KLOZUR® achieves improved subsurface distribution, expanding the radius of influence and allowing more time for contaminant contact and degradation—leading to more effective remediation outcomes.
Versatile Application Across Diverse Site Conditions

Our KLOZUR® persulfate product portfolio
KLOZUR® SP is a highly soluble, microfine, and environmentally compatible sodium persulfate specifically developed for in situ chemical oxidation (ISCO) in the source zones of contaminated sites. It is ideally suited for the treatment of chlorinated solvents, total petroleum hydrocarbons (TPH), and polycyclic aromatic hydrocarbons (PAHs) in soil and groundwater.
When properly activated, KLOZUR® SP delivers exceptional oxidation performance, enabling safe, controlled, and cost-effective remediation. Its combination of high reactivity and reliable monitoring capabilities makes KLOZUR® SP a trusted solution for even the most challenging remediation projects.
KLOZUR® CR is a single, formulated product that combines alkaline-activated KLOZUR® SP with PERMEOX® Ultra engineered calcium peroxide, delivering a powerful dual-action approach to in situ chemical oxidation (ISCO). This innovative blend harnesses the strengths of both components to effectively treat contaminant source zones and downgradient plumes in soil and groundwater.
By integrating fast-acting and sustained-release oxidants, KLOZUR® CR provides enhanced reactivity, extended treatment longevity, and broad applicability across complex site conditions—making it a reliable solution for challenging environmental remediation projects.
KLOZUR® KP is a high-purity, environmentally friendly potassium persulfate designed for in situ chemical oxidation (ISCO) in soil and groundwater remediation. It reliably treats chlorinated solvents, total petroleum hydrocarbons (TPH), and polycyclic aromatic hydrocarbons (PAHs), making it a versatile solution for a wide range of contamination scenarios.
Thanks to its controlled-release properties, KLOZUR® KP is especially well-suited for permeable reactive barrier (PRB) applications, contaminant plumes, and low-permeability zones. It can be flexibly applied via slurry injection or in situ soil mixing, offering a safe, controllable, and cost-effective remediation approach.
KLOZUR® ONE is a fully soluble, all-in-one product that combines KLOZUR® SP with specially selected activator reagents, streamlining the application of persulfate-based chemistry for in situ chemical oxidation (ISCO). Designed for use in a single injection system, it is ideal for treating heavily contaminated source zones and contaminant plumes in soil and groundwater.
This ready-to-use formulation simplifies ISCO implementation, enabling efficient, safe, and cost-effective remediation directly at the contamination site. KLOZUR® ONE reduces complexity while maximizing performance—making it a smart choice for demanding environmental cleanup projects.
