Persulfates for soil and groundwater remediation

KLOZUR® ONE

As an all-in-one product containing KLOZUR® SP and carefully selected activator reagents, KLOZUR® ONE can be fully dissolved and prepared using a single injection system. KLOZUR® ONE simplifies and increases the convenience of delivering activated KLOZUR® persulfate in field applications.

KLOZUR® ONE builds upon the successful history of KLOZUR® SP by delivering activated persulfate chemistry more conveniently than ever before. This fully soluble product will simplify and increase the convenience of delivering KLOZUR® activated persulfate in field applications. KLOZUR® ONE’s chemistry has been tested to show effective treat many common COCs while having the necessary stability to be stored, batched, handled and transported with the same hazard classification as KLOZUR® SP. 

KLOZUR® ONE is well suited for:

  • Most common contaminants of concern
  • Source areas and plumes

KEY BENEFITS

  • Combined activator and KLOZUR® SP in a single product
  • Multiple activation pathways
  • Completely soluble
  • Trace permanganate provides visual indicator

EXAMPLE CONTAMINANTS

  • Chlorinated ethenes
  • Petroleum hydrocarbons
  • BTEX

POTENTIAL APPLICATIONS

  • Injection through constructed wells or direct push technology (DPT) rods
  • Soil mixing or blending
  • Amended to the base or fill for an excavation

TECHNOLOGY: IN SITU CHEMICAL OXIDATION

In situ chemical oxidation (ISCO) is the introduction of an oxidant into the subsurface for the purpose of oxidizing contaminants in soil and groundwater. ISCO is ideal for the elimination of contaminant concentrations in source zones and hot spots.

Technical Documents

As KLOZUR® persulfate is a very strong oxidant, and its solutions may become very acidic (pH ≤2), persulfate solutions may result in a corrosive environment for many metals and materials.

Methyl-tert-butyl ether (MTBE) and tert-butyl alcohol (TBA) are environmental contaminants of concern that have been widely used as fuel oxygenates and octane boosters.

KLOZUR® sodium persulfate is a stable, highly soluble, crystalline material, which upon activation is capable of oxidizing a broad range of recalcitrant compounds.

KLOZUR® ONE Webinars

Dr. Brant Smith introduces KLOZUR® ONE, a new addition to our KLOZUR® product portfolio of powerful oxidants.

Dr. Brant Smith discusses critical elements for developing an activated KLOZUR® persulfate field application, including critical design parameters, scaling lab-scale results, and various methods.

Dr. Brant Smith discusses the monitoring programs necessary for a remedial approach using KLOZUR® persulfate, as well as best practices for assessing its effectiveness.

Brianna Desjardins and Brant Smith explain the lab-scale testing that the Environmental Solutions Laboratory typically performs on us for EHC® Reagent, ELS™ Microemulsion, KLOZUR® persulfate, MetaFix® Reagent, and hydrogen peroxide. 

Evonik’s laboratory created the KLOZUR® field test kit to provide a quick and reliable measurement of persulfate in the field.

There are two different kits available, depending on the activation method used. Each kit is capable of running ten tests and has a measurement range of 1g/L to 100g/L, with a theoretical accuracy of ±1g/L and ±2g/L respectively.
