Frost & Sullivan awards ThermoEnergy Ammonia Recovery Processes

PALO ALTO, Calif., Nov. 17 /PRNewswire/ -- Frost & Sullivan has selected
ThermoEnergy Corporation as the recipient of the 2005 Technology Innovation
Award in the municipal and industrial wastewater treatment market for its
contributions to the advancement of environment-friendly wastewater treatment
processes. This award specifically recognizes the company's ammonia recovery
process (ARP) that converts the ammonia found in wastewater plants to ammonium sulfate, a commercial grade fertilizer; and the ThermoFuel process, a
renewable energy technology which enables upgrades of wastewater treatment
facilities to Exceptional Quality (EQ) standards.

Each year, Frost & Sullivan presents the Technology Innovation Award to a
company that has carried out new research; which has resulted in innovation(s)
that have or are expected to bring significant contributions to the industry
in terms of adoption, change, and competitive posture. The award lauds the
quality and depth of a company's research and development program as well as
the vision and risk-taking that enabled it to undertake such an endeavor.

"Significantly, ARP is the only ammonia removal technology that reclaims
ammonia for use in a consumer-ready fertilizer product," says Frost & Sullivan
Research Analyst Miriam Nagel. "The twice-patented process has received
verification from the Environmental Protection Agency (EPA) under the
Environmental Technology Evaluation Program."

ARP has proved its efficacy even in large-scale demonstration projects
such as the one with the New York City Department of Environmental Protection
in 1998, and in Colton, California in 2000. These demonstration projects led
to a $7 million contract with City of New York, where the ARP process will be
used to significantly reduce the discharge of nitrogen (ammonia) from the
Bowery Bay water pollution control plant into the Upper East River, which will
improve water quality within the Long Island Sound.

The ARP process extracts ammonia from wastewater using reversible
chemisorption techniques and converts it into standard commercial-grade
ammonium sulfate fertilizer. ARP is primarily used for municipal wastewater
treatment and the curing of wastewater discharge from large concentrated
animal farming operations including dairy, pork, beef, and poultry facilities.
As a pioneer of advanced wastewater treatment technology, ThermoEnergy
continues to optimize the ARP process design in its engineering and laboratory
facilities near Boston, MA. One of the results is the expansion of its
treatment capability over a range of ammonia concentrations, from 10 to more
than 10,000 parts per million, to recover a concentrated ammonium sulfate

Meanwhile, the ThermoFuel process combines advanced primary sludge
digestion with hydrothermal treatment of waste-activated sludge to expand the
capacity of municipal wastewater facilities. This creates biosolids with the
least health risk and it also assists in upgrading wastewater treatment plants
to the EPA-designated EQ class.

"Apart from the ARP technology and the ThermoFuel process, ThermoEnergy's
wastewater treatment technologies include the patented Enhanced Biogas
Production process, which significantly improves digester performance and
methane production," notes Nagel. "The company has also developed the
ThermoEnergy Integrated Power System (TIPS) process, an advanced power plant design that converts fossil fuels and biomass into energy without producing
air emissions."
