New Remediation Biotechnology for NAPL
Sites
Carus Corporation and The Adventus Group form
partnership to offer innovative RemOx® EC
Stabilization Reagent technology

PERU,
IL (Jan. 9, 2007) – Carus Corporation, the
world’s largest and only domestic manufacturer
of permanganates, and The Adventus Group, an
international environmental biotechnology firm,
announced their collaboration to introduce RemOx®
EC Stabilization Reagent. Designed for
hard-to-treat non-aqueous phase liquid (NAPL)
sites, this innovative and cost-effective
technology is ideal for manufactured gas plants,
wood treating facilities, petroleum product
refineries, and related sites impacted by
organic constituents of interest (COI) as well
as heavy metals. All global sales and
distribution activities will be channeled
through Carus Chemical’s Hazardous Remediation
Team, headed by Matthew Dingens.
How it works
RemOx® EC in situ biogeochemical stabilization
entails the use of modified permanganate
solutions for the purposes of mass removal and
flux reduction (i.e., NAPL stabilization). As
the oxidant migrates through the treatment area,
various (bio)geochemical reactions destroy the
targeted compounds present in the dissolved
phase. This causes a “hardening” or "chemical
weathering” of the NAPL as it steadily loses its
more labile components. This causes a net
increase in viscosity of the organic material,
which yields a more stable, recalcitrant
residual mass. In addition, the insoluble MnO2
precipitate that results from catalyzed
permanganate oxidation will accumulate along the
NAPL interface, physically coating it and
thereby reducing the flux of dissolved-phase COI
into the groundwater.
The firms summarized key benefits of using RemOx®
EC for sites impacted by hard-to-treat NAPLs as:
• Rapid source stabilization
• Dramatically reduced source flux
• High compatibility with natural attenuation
technologies
• Half the historical cost of current
conventional alternatives
“When Dr. Carus founded this company in 1915, he
fostered a commitment to provide innovative
products and services for our customers which
are designed to help them meet or exceed their
business objectives. The Adventus Group’s
similar mission and complementary remediation
biotechnologies led to this exciting
collaboration,” Inga Carus, president and CEO of
Carus Corporation. “The pricing models have
indicated outstanding value, with RemOx® EC
being a very competitive alternative for NAPL
type situations, where, for example, thermal
destruction can range from $300 to $500/m³, and
ISCO can approach the same. We are confident
clients around the world will be taking a close
look at this alternative. On behalf of the
associates at Carus, we welcome this chance to
work with Adventus and are confident this
strategic relationship will result in
considerable improvements to our environment.”
According to Jim Mueller, president of Adventus
Americas Inc., “We have identified a wide
variety of industries, regulators, and reputable
consultancies that are currently considering
this option to proactively address NAPL concerns
throughout the world. Large-scale field trials
in Alabama, Florida, Colorado and Europe are in
various stages of operation. Our scientists and
engineers continue to work with various MGP
owners and their consultants to implement the
RemOx® EC technology in this important market
sector. We look forward to pursuing the many
market opportunities this strategic partnership
with Carus will produce.”
