Cogen : From Dairy Waste to
Electric Power
 Potsdam,
NY -- Cow manure, waste silage, cheese whey are waste
products to some, but viable energy sources to enterprising
Clarkson University researchers who are helping area farmers
meet their own energy needs.
Last year's New York State budget
included a $1-million appropriation for Clarkson to
investigate ways that dairy waste from cheese manufacturing
and dairy farms can be used as feedstock to produce biogas
to generate heat and electric power on New York farms.
"Biogas derived from the
anaerobic digestion of manure and whey represents an
important biofuel that could provide significant economic,
environmental and social benefits at thousands of farms,"
says Stefan Grimberg, associate professor of civil &
environmental engineering. "Farmers and dairy processing
facilities can displace purchased sources of heat and power,
reduce wastewater treatment and environmental compliance
costs, and mitigate exposure to fluctuating power prices."
Grimberg is the principle
investigator on a $2-million project to design and build an
anaerobic digester and power/heat recovery system at a
working dairy farm in Jefferson County, N.Y. The
interdisciplinary research team from Clarkson also includes
electrical engineers and social scientists.
The researchers will use the
project to showcase emerging technologies. The project also
promises to yield important improvements over current
digester technologies through the development of an
optimization model for the integrated energy system and
through mechanisms to separate sand used for bedding from
the manure.
"More than half the anaerobic
digesters built before the mid-1980s failed to operate
properly," Grimberg explains. "We are interested in
improving the technology and reliability of the system."
In-depth interviews with New York
state farmers that have installed anaerobic digesters are
being performed in order to discern the motivations for
adopting the technology as well as how anaerobic digestion
technology is integrated into their farming systems.
"There is very little data
available on farm-level perceptions, knowledge and attitudes
toward anaerobic digester technology," explains Associate
Professor of Sociology Rick Welsh, a member of the research
team. "Such data is critical to inform the design of
anaerobic digesters, as well as to create public policy that
can provide helpful information to farmers about their
options in this area."
The team will also complete a
lifecycle accounting of the environmental benefits from
diverting waste products to an energy system and the
associated displacement of fossil fuel sources.
Researchers plan to use the model
as a basis for extending digester/energy system technologies
across the North Country, which could eventually be
implemented on a wider commercial scale. "This pilot study
represents that important intermediate step in technology
transfer between initial laboratory research and
commercialization," says Grimberg.
The project has also received
support from the New York State Energy Research and
Development Authority, the Department of Energy and the
United States Department of Agriculture.

Severn
Trent Receives Silica Removal Patent
 FORT
WASHINGTON, PA -- Severn Trent Services has received U.S. Patent
Number 7,153,434 for its technology related to a method for
removing silica from water treatment adsorption media. Severn
Trent Services has exclusive rights to this technology.
Severn Trent Services’ novel method
solves the problem of silica interference of arsenic and other
contaminant treatment adsorption media. Silica, or silicon
dioxide, exists naturally in many groundwater sources.
When the groundwater passes through a
bed of adsorption media, the silica present in the groundwater
is believed to encapsulate the media particles and acts as a
barrier to adsorption of other contaminants. The silica coating
clogs the pores of the adsorption media and severely limits the
ability of the media to remove contaminants from the water.
The intermittent addition to the
media bed of a scrub solution composed of NSF-approved products
can significantly increase the adsorptive capacity of the bed.
The arsenic removal media bed soaks in the scrub solution until
silica is removed from the media particles, usually 20 minutes
at the beginning of a routine backwash cycle. The scrub solution
containing the silica is then removed and the media bed flushed
during a normal backwash.
About Severn Trent Services
Severn Trent Services, based in Fort
Washington, Pa., is a leading supplier of water and wastewater
treatment solutions. The company’s broad range of products and
services is concentrated around disinfection, instrumentation,
and filtration technologies, contract operating services and
state-of-the-art residential metering products and services.

Mr. Spruce wants help with wash water odor:
I am involved with a
investigation into improving a wash water treatment plants
performance. Wash water (oil and grease and surfactants) is
treated by oil separation, followed by flocculation,
settling and filtration. The configuration is a little
strange - side streams off a main " treatment tank" then
storage.
The problem is the plant
produces a clean but odorous effluent. I suspect that the
dissolved surfactants are adding a COD load which is then
reacting, either aerobically or anaerobically.
My first thought is to
reconfigure the system into an aeration, filtration and then
storage treatment train -but I am concerned about the
foaming potential.
Any thoughts would be
appreciated. (Click

Ms. Christoforidou needs help measuring COD:
I am trying to measure the
