Klozur® portfolio

Power. Stability. Versatility

When activated with Evonik’s patented technologies, KLOZUR® persulfates form powerful oxidative and reductive radicals that effectively treat a wide range of contaminants, including chlorinated solvents, petroleum hydrocarbons, and PAH’s. Our proven patented activation methods include alkaline (high pH), chelated metals, hydrogen peroxide, heat, and zero valent iron.

About Klozur®

Activated KLOZUR® persulfate creates a multi-radical attack providing greater oxidation power capable of treating common and the most recalcitrant compounds alike.

The stability of KLOZUR® allows it to be better distributed in the subsurface providing a greater radius of influence and allowing more time to make contact and degrade contaminants.

With a variety of activation and delivery methods, the versatility of the KLOZUR® portfolio is unmatched, allowing it to be applied at a wide variety of site conditions.

Evonik is one of the world’s largest producers of persulfates and the only persulfate manufacturer in North America. Having over 80 years of persulfate manufacturing experience, Evonik’s team has developed the standards for persulfate application guidance, safety and handling, and storage.

Our KLOZUR® persulfate portfolio

KLOZUR® SP treats a wide range of contaminants such as petroleum hydrocarbons and chlorinated solvents, making it perfectly suited for in situ chemical oxidation.

KLOZUR® KP is an extended release reagent for in situ chemical oxidation (ISCO) and is characterized by low solubility. It can be used for a variety of applications not traditionally intended for chemical oxidation.

KLOZUR® CR is a single formulated product consisting of alkaline activated KLOZUR® SP and PermeOx® Ultra engineered calcium peroxide that combines the strengths of both products to treat contaminant sources and downgradient plumes.

KLOZUR® ONE is a fully soluble, all-in-one product containing Klozur SP and thoroughly selected activator reagents that can be prepared using a single injection system for the treatment of highly contaminated source areas or plumes.
