RemRx® CRP

Eliminating the Rebound

Over time, contaminants change physical states.

RemRx® CRP delivers a sustained oxidant with a single application
that continually treats dissolved phase contaminants.

What Causes Rebounding?

Contaminant mass can be dissolved in groundwater, sorbed onto solids in the aquifer sediment and as a separate non-aqueous base.

The contaminant concentrations are the result of the dynamic combination of the aquifers environment, solubility and the groundwaters pH.

Oxidant and contaminant reaction kinetics are faster in the dissolved phase thus sorbed contaminants are not as efficiently treated. Rebounding occurs when contaminant desorb and partition back into the aqueous phase.

Learn more about these physical state changes in our webinar series below.

Control Release ICSO

A Single Treatment

Our controlled release ISCO provides a sustained delivery of oxidants into the subsurface continually degrading contaminants and mitigating rebound.

RemRx® CRP delivers a sustained oxidant with a single application that continually treats dissolved phase contaminants.

Versatile & Tunable

A Prescriptive Dosage

Complicated hydrogeological aspects in the subsurface mean that each contaminated site is unique.

We use a highly tunable polymer-based matrix that allows release of targeted oxidant doses under specific treatment times and conditions.

Our tunable technology allows for a prescriptive remediation strategy that is not possible with traditional dissolved oxidant solutions.

Currently available as permanganate and persulfate.

Deployment Versatility

The easy to handle, solid material can be placed directly into the contaminated zone, established in a permeable reactive barrier, or spread throughout an area following excavation as a “polishing” step.
