Treatment Train with Slow Release Oxidants

Use of Remox SR+ Cylinders in Treatment for Chlorinated Solvents in Groundwater

Presenter: 
Grant Walsom

Summary:
Historical industrial activities using solvents for metal degreasing as well as dry-cleaning operations have created many remediation challenges. Innovative and cost-effective methods for treatment of chlorinated VOCs (typically PCE, TCE, C-DCE, and vinyl chloride) in soil and groundwater continue to evolve with new products and applications.

Carus Corporation’s RemOx® SR+ ISCO reagent is a solid form of permanganate and persulfate encased in a paraffin wax that slowly releases the oxidants into the subsurface for a prolonged treatment of the chlorinated VOCs. The solid form is easy and safe to install, while the prolonged treatment ability provides the ability to continue to treat the VOCs long after installation.

XCG Consulting Limited has successfully employed RemOx SR+ cylinders at four different sites in Ontario with varied geological settings. One of the sites was the first RemOx SR+ application in Canada.

This presentation briefly describes the product and advantages of its use while exploring case studies and their successes through sharing site-specific data.
