Technologies Inc. (Adventus) is a 100% Canadian owned environmental technology
company that provides various environmental remediation technologies including
DARAMEND® and TERRAMEND for treatment of soil and sediment, AQUAMEND®
for wastewater, and EHC and mGCW systems for in situ groundwater treatment.
Along with our US affiliate, Adventus Americas Inc., Adventus provides biotechnology-based
remedial solutions that effectively manage complex, challenging environmental
liabilities, while saving our clients significant time and money.
Our
technically superior remediation solutions are proven to treat a wide range of
organic contaminants by accelerating their natural attenuation in soil, sediment
and ground water. Furthermore, our sister company EnviroMetal Technologies Inc.
(ETI) is the worldwide leader in applications of permeable reactive barrier (PRB)
technology for the remediation of contaminated groundwater. ETI provides a range
of advisory and support services to site owners, remediation consultants, and
contractors to assist them with the design and installation of our patented zero
valent iron PRB systems as well as other passive remediation technologies. A 10-year
record of successes in Adventus' application of technologies to solve complex
environmental problems began within the W.R. Grace & Co. organization (NYSE:GRA).
Our portfolio of remediation successes enables us to uniquely guarantee
the performance of our products and services. Adventus specializes in remedial
solutions. Our business model is to support a project team by aiding in the design s
and selection of the most cost-effective remedial solution or strategy without
predisposition or bias to the selection of our proprietary technologies. When
their application is justified, however, our proven products may provide significant
advantages, and then we provide these. We subsequently rely on select consultancies
to support joint projects especially from engineering and construction (oversight)
perspectives. Adventus technical experts specialize in soil microbiology, bioremediation,
remediation design support, ground water modeling and project management. After
reading this section and attending this demonstration the attendee will have a
thorough knowledge of Adventus Remediation Technologies (Adventus) products and
services. Adventus is an environmental services company that provides various
environmental biotechnologies including DARAMEND® and TERRAMEND for
treatment of soil and sediment, AQUAMEND® for wastewater, and EHC and
mGCW systems for in situ groundwater treatment. Our sister company EnviroMetal
Technologies Inc. (ETI) is the worldwide leader in applications of permeable reactive
barrier (PRB) technology for the remediation of contaminated groundwater, with
experience in United States, Canada, United Kingdom, Europe, Japan and Australia.
ETI provides a range of advisory and support services to site owners, remediation
consultants, and contractors to assist them with the design and installation of
our patented PRB systems and other passive remediation technologies. Demonstration: Due
to the nature of Adventus' and ETI's technologies a table-top demonstration will
be set up to provide information regarding the above technologies. A brief description
of each of these products, and their applicability, is provided below.
DARAMEND®
-- advanced biological treatment technology for soil, sediment, and solid wastes
contaminated with recalcitrant organic compound. DARAMEND has been used successfully
throughout the world to treat over 800,000 tons of soil, sediment and solid wastes
containing persistent organic contaminants such as chlorinated pesticides (Toxaphene,
DDT, dieldrin), wood preservatives and organic explosives (TNT, DNT, RDX, HMX).
EHC -- a controlled-release, integrated carbon and zero valent iron
(ZVI) source that yields redox potential (Eh; hence EHC or Redox compound) in
the -500 to -650 mV range. This Eh is significantly lower than that achieved when
using either organic materials (lactate, molasses, and sugars) or reduced metal
alone. Eh potentials in this range facilitate the timely and effective removal
of normally recalcitrant chlorinated organics (e.g., CT, PCE) and other persistent
compounds without the formation of potentially problematic intermediates, such
as DCE/VC from the anaerobic degradation of PCE/TCE or CF/DCM from the anaerobic
degradation of CT. Also available are EHC-M for immobilization of metals and EHC-O,
an oxygen supply compound that is significantly more effective and less expensive
than competitive products. TERRAMEND -- inorganic soil amendments
that provide an optimized balance of major, minor and micronutrients designed
to cost-effectively enhance bioremediation of soils, sediments and solid wastes
impacted with petroleum hydrocarbons, including gasoline, diesel fuel, jet fuel,
heating oil, bunker-C and a wide variety of other petroleum-based compounds. TERRAMEND
technology offers the cost-effective reduction of petroleum hydrocarbon concentrations
in soils, can often be applied without excavation, generates no odors or leachate,
and does not result in bulking. AQUAMEND® -- a highly efficient,
stable, biological water treatment technology based on the use of specialized
biocarriers and site-specific process optimization. AQUAMEND biocarriers are specially
designed to enable dense bacterial colonization and to provide protection for
microorganisms. AQUAMEND technology has been proven to provide low maintenance,
cost effective treatment of industrial process water and groundwater containing
a range of compounds including pentachlorophenol, VOCs, base neutral acid extractables
(BNAs), chlorinated organics, PAHs, petroleum hydrocarbons, high COD/BOD, landfill
leachate, pesticides and herbicides, organic explosives, ammonia, as well as industrial
and municipal nitrate. mGCW - microbiologically enhanced vertical groundwater
circulation well (mGCW) technology significantly modifies conventional GCW systems
to effect the removal of inorganic constituents (e.g., heavy metals and nitrate)
and/or accelerate the biodegradation of persistent organic compounds under aerobic
(e.g., high molecular-weight PAHs) or anaerobic (e.g., organic explosives, chlorinated
hydrocarbons) conditions. The mGCW systems are specifically designed and uniquely
configured to provide accelerated aerobic, enhanced anaerobic or sequential anaerobic/aerobic
reactions. These reactions facilitate terminal destruction of persistent organics,
appropriately coupled with the removal of inorganic constituents where needed.
The mGCW system treats soil and groundwater simultaneously by drawing groundwater
from an aquifer formation through one screen section of a multi-screened well
and discharging it through another. This creates an in situ vertical groundwater
circulation cell. ISBS - In situ biogeochemical oxidation for the
purposes of NAPL stabilization entails the use of modified permanganate solution
(KMnO4, or NaMNO4) that is flushed through an aquifer zone suspected to contain
residual NAPL. As the oxidant migrates through the targeted zone, various (bio)
geochemical reactions occur between the organic COI and the oxidant, which cause
the destruction or removal of NAPL. The more water soluble, the lower-molecular-weight
NAPL constituents are removed at a proportionally higher rate, thus leading to
a "hardening" or chemical "weathering" of the residual NAPL
as it steadily loses its more labile components. This causes a net increase in
NAPL viscosity, which yields a more stable, recalcitrant residual mass. In addition,
the enhanced precipitation of MNO2 along the NAPL interface results in a physical
coating which further reduces the flux of dissolved-phase constituents into the
groundwater thereby facilitating enhanced natural attenuation processes. PRB
- Permeable reactive barriers. ETI has the exclusive commercialization rights
to a patented process developed by the University of Waterloo, Waterloo, Ontario,
Canada that uses zero-valent metals (commonly granular iron) to rapidly degrade
halogenated volatile organic compounds (VOCs) in groundwater to non-hazardous
end products. This technology known as granular iron reactive zones or iron PRB
technology, has been accepted in the marketplace through over 125 applications
around the globe and a 10 year track record of successful field performance. Its
technical feasibility has been evaluated and supported through the publication
of over 500 scientific papers [cgr.ese.ogi.edu/ironrefs]. ETI's clients including
major U.S. government agencies (DoD, DOE, NASA) and large industrial companies
(i.e., General Electric, Rockwell, E. I. DuPont deNumors) have recognized ETI's
technology as a cost-effective long-term alternative for remediation of chlorinated
compounds. PEOPLE Adventus is managed by an established team of
environmental professionals representing over 100 years of experience in the hazardous
