CDM : Providing Environmental
Expertise to USAID
 ARLINGTON,
VA -- The U.S. Agency for International Development (USAID)
has selected a CDM-led team to be one of three consortia to
carry out projects under the 5-year, $250 million
environmental health indefinite quantity contract, a
far-reaching technical support contract to alleviate many of
the most critical health challenges facing today's global
population.
The
program supports USAID's continued successful work in 12 key
areas of environmental health, with the overall objective of
reducing childhood morbidity and mortality in developing
countries by reducing exposure to agents of disease and to
environmental hazards that exacerbate disease. Priority
areas include water supply and sanitation; solid waste
management; vector control; infection control, including
medical waste management and improved hygiene in health
facilities; integrated programming of
population-health-environment activities in areas of
sensitive biodiversity; and indoor air pollution.
Throughout the program, CDM and its partners will apply the
technical and program management expertise garnered during
the firm's long history implementing large-scale, flagship
projects for USAID, including award-winning programs such as
the 15-year Water and Sanitation for Health Project and the
decade-long Environmental Health Project, completed this
year.
"CDM
is honored once again to have the opportunity to work with
USAID to support its long-term environmental health
initiatives. This award continues a 25-year tradition of
collaborating with USAID on projects that contribute
significantly to improving human health and addressing
environmental health on a global scale," says J. Ellis
Turner, CDM senior vice president.
CDM is
a global, full-service consulting, engineering,
construction, and operations firm helping public and private
clients improve the environment and infrastructure.

CSU : Study Finds Antibiotics
Can Make Their Way Into Waterways
 FORT
COLLINS, CO - A Colorado State University study is the first
to show that antibiotic drugs used specifically for
enhancing growth, preventing diseases and increasing feed
efficiency in food animals, such as cattle, are making their
way into public waterways.
The
study, which identifies antibiotics in waterways that come
from both human and animal uses, is the first to pinpoint
drugs specifically from animal sources. For example, the
antibiotic monensin, used exclusively in agricultural
applications for growth enhancement in cattle, is used as a
marker in the study and was measured only in waterways
located near animal feeding operations. The study also is
among the first to measure the compounds in stream and river
bed sediment and found that the concentration of antibiotics
was 20 times to 1,000 times greater in sediment than in the
surrounding water.
According to a separate collaborative Federal Drug
Administration and Colorado State College of Veterinary
Medicine and Biomedical Sciences environmental assessment
for the use of monensin in the feed of beef cattle, these
levels are below concentrations that could result in
environmental impact or effects on human health. The
antibiotic study's authors also point out that the results
do not necessarily implicate waste management practices of
animal feeding operations, but rather reveal that animal
antibiotics are making their way into streams and rivers.
"The
presence of antibiotics in waterways drives two primary
concerns," said Ken Carlson, associate professor of civil
engineering and principal investigator of the project. "The
first is the potential toxic dangers of these compounds to
fish, plants and other aquatic organisms - as well as to
humans through drinking water - because water treatment
plants generally cannot remove all of these compounds. There
is also a potential, which we are currently studying, that
these types of animal and human antibiotics have on
contributing to the emergence of strains of disease-causing
bacteria that are resistant to even high doses of drugs."
Carlson added that future studies are needed to determine
exactly how the antibiotics make their way into public
waterways, how long the drugs stay in water and sediment and
to better understand potential dangers to aquatic life,
animals and humans. The presence of pharmaceutical compounds
in urban wastewater discharge also is recognized as an
important issue and is being studied by researchers across
the country.

USFilter : Awarded Canadian Patent For Adsorption
Clarifier Media
 AMES,
IA -- The Canadian Intellectual Property Office has issued
Canadian patent number 2,163,203 to USFilter Corporation
for its Microfloc Products’ rolled and scarified buoyant
Adsorption Clarifier® media.
The Adsorption Clarifier® media
is manufactured from high-density polyethylene plastic
beads, which float in water. During operation coagulated
solids are passed upward through the media at high rates
where in-bed flocculation and contacting occur.
Flocculated solids are captured in the upflow clarifier
bed reducing influent turbidity by 70-90 percent. Captured
solids are periodically flushed from the bed using air and
raw water simultaneously.
The patent covers the design
improvement where the round media beads are rolled and
scarified. Rolling the beads provides an elongated shape
to form a tighter packed bed. Scarification places an edge
on the elongated beads providing increased surface area
and a location for flocculated particles to adhere. Both
design improvements provide a greater degree of
flocculated particle removal and a higher quality
effluent.
Adsorption clarifier media is
in use in over 700 water treatment units around the world.
Most applications are in the Microfloc Trident® family of
treatment units, which are pre-engineered treatment plants
with an integral adsorption clarifier and mixed media
filter.
The patent provides similar
patent protection as that already in place in the United
States.
USFilter Corporation, a Siemens
company, delivers cost-effective, reliable water and
wastewater treatment systems and services to municipal,
industrial, commercial and institutional customers
worldwide. USFilter is part of Siemens' Industrial
Solutions and Services Group (I&S), which provides
innovative solutions and services designed to improve
competitiveness in processing and manufacturing industries
and in infrastructure.

Dr. Fein
wants to know more about a dewatering press:
I am interested hearing
from anyone who uses the Netzsch Contipress for dewatering
WAS. We have recently tested a small pilot unit on
our WAS and the results were quite positive.
I am interested in hearing
about how well the technology performs at full scale, in
particular, over long term operation. How mechanically
reliable and trouble free do you find it? How does it
compare to other WAS-dewatering technologies you may have
used (e.g. centrifuge).

Mr. Schmidt needs
help shutting down his WWTP:
Our plant is just finishing
it's first season. We are closing for the winter and need to
put the system to bed. It is an activated sludge plant and
sand filter.
I plan on pulling all of the
pumps and diffusers. I can pump the EQ over without
any problem, but what do I do about the aeration tank and
clarifier? Combined it's about 30,000 gallons and would be
very expensive to pump out and haul away. Can it be left
over the winter and rejuvenated in the spring?
