WWTP's create
antibiotic-resistant Superbugs
 ANN
ARBOR, MI -- For bacteria in wastewater treatment plants,
the stars align perfectly to create a hedonistic mating
ground for antibiotic-resistant superbugs eventually
discharged into streams and lakes.
In the first known study of its
kind, Chuanwu Xi of the University of Michigan School of
Public Health and his team sampled water containing the
bacteria Acinetobacter at five sites in and near Ann Arbor's
wastewater treatment plant.
They found the so-called
superbugs—bacteria resistant to multiple antibiotics—up to
100 yards downstream from the discharge point into the Huron
River. Xi stresses that while the finding may be disturbing,
it is important to understand that much work is still needed
to assess what risk, if any, the presence of superbugs in
aquatic environments poses to humans.
"We still need to understand the
link between aquatic and human multiple drug resistant
bacteria," said Xi, assistant professor of public health.
Xi and colleagues found that
while the total number of bacteria left in the final
discharge effluent declined dramatically after treatment,
the remaining bacteria was significantly more likely to
resist multiple antibiotics than bacteria in water samples
upstream. Some strains resisted as many as seven of eight
antibiotics tested. The bacteria in samples taken 100 yards
downstream also were more likely to resist multiple drugs
than bacteria upstream.
"Twenty or 30 years ago,
antibiotics would have killed most of these strains, no
problem," he said.
Multiple antibiotic-resistant
bacteria has emerged as one of the top public health issues
worldwide in the last few decades as the overuse of
antibiotics and other factors have caused bacteria to become
resistant to common drugs. Xi's group chose to study
Acinetobacter because it is a growing cause of
hospital-acquired infections and because of its ability to
acquire antibiotic resistance.
Xi said the problem isn't that
treatment plants don't do a good job of cleaning the
water—it's that they simply aren't equipped to remove all
antibiotics and other pharmaceuticals entering the treatment
plants.
The treatment process is fertile
ground for the creation of superbugs because it encourages
bacteria to grow and break down the organic matter. However,
the good bacteria grow and replicate along with the bad. In
the confined space, bacteria share resistant genetic
materials, and remaining antibiotics and other stressors may
select multi-drug resistant bacteria.
While scientists learn more about
so-called superbugs, patients can do their part by not
insisting on antibiotics for ailments that antibiotics don't
treat, such as a common cold or the flu, Xi said. Also,
instead of flushing unused drugs, they should be saved and
disposed of at designated collection sites so they don't
enter the sewer system.
The next step, said Xi, is to see
how far downstream the superbugs survive and try to
understand the link between aquatic and human superbugs.
This study did not look past 100 yards.
Xi's colleagues include visiting
scholar Yongli Zhang; Carl Marrs, associate professor of
public health; and Carl Simon, professor of mathematics.

Low
Carbon-Footprint Sewage System is “The Future”
 Norfolk,
UK -- Unveiling a plaque to commemorate the official opening
of the new odor-free sewage plant at Sutton St. James in
Lincolnshire, the Rt. Hon. Hilary Benn, Secretary of State
for the Environment, Food and Rural Affairs proclaimed the
system represented the “future of sewage treatment”.
At the heart of a £4 million
first time sewerage scheme, the low energy Aero-Fac®
treatment plant utilizes wind power to minimize treatment
costs.
John Forkin, Anglian Water
Contracts Manager, said: “We are committed to providing
environmentally friendly and cost efficient solutions. The
Aero-Fac system offers a low carbon footprint solution both
for construction and the long term operational costs. The
system has no odor during normal operation and the earth
banks around the cells give a visual aspect which is in
keeping with the rural environment.”
John Gillett, Managing Director
of Gurney Environmental Ltd., explains the Aero-Fac system
incorporates a number of unique features.
“Not the least of which is a
self-digesting sludge process that requires no
pre-screening, sedimentation tanks or clarifiers, no sludge
removal, dewatering or conditioning, and best of all, no
routine sludge disposal and the associated lorry traffic in
and out of the works. All sludge is continuously self
digested within the initial treatment stage. The Sutton St.
James plant is also the first in the U.K. to incorporate the
Bio2Bloc® ammonia removal process.”
This modular, floating SAF system
enables year-round compliance with ammonia consents but, in
keeping with the overall design philosophy, minimizes energy
consumption by operating only when needed.
The new plant at Sutton St. James
is designed to provide wastewater treatment for
approximately 830 people and was judged by Anglian Water to
have the lowest overall carbon footprint of all the
considered alternatives. The project was delivered by the
@One Alliance which is a collaboration between Anglian
Water, Grontmij and Barhale Construction Ltd.
Anglian Water's commitment to
lowering its carbon footprint continues with the
construction of three more Aero-Fac and Accel-o-Fac® plants
due for completion later this year.

Aeration Industries Receives
2008 EBJ Award
 Chaska,
MN -- Aeration Industries International, Inc. is pleased
to announce that it has received an Environmental
Business Journal (EBJ) Business Achievement Award in the
category of “Technology Merit: Water/Wastewater” for the
successful deployment of its Tri-Oval® Oxidation Ditch
Wastewater Treatment System.
The Tri-Oval System integrates the company’s innovative
Aire-O2 Triton process aerator/mixer into the Oxidation
Oval format, providing subsurface horizontal mixing at
sufficient velocities to prevent solids from settling.
This permits longer entrainment of the unit’s fine
bubble diffused air and allows for deeper ditch designs
with smaller footprints.
The mounting of the Triton units in the ditch is clean
and simple eliminating the need for complex concrete
structures and making access for inspection and
maintenance very easy.
The subsurface action of the Triton units eliminates the
need for covers. And the dual mode functionality of the
Triton units allows for unsurpassed process control for
BNR treatment without inhibiting mixing resulting in
energy conservation and high effluent quality.
Recognition of these advantages in the industry has
recently led to the design and construction of three new
Tri-Oval oxidation ditches in 2008 with the first placed
into service in North Dakota at the end of 2008.

Nasir needs to choose between
a filter press or belt press:
I want to know what is the
main difference between the filter press and the belt press.
How to decide before selecting the filter?
I have already worked on
filter press in oil recycling, but I have no idea about the
belt press. It seems that belt press are more complex in
construction and operation and may require more maintenance
than the filter press.
I would appreciate if any
body with an experience in belt press operation can help me. (Click

mammoth DTSS conveys used water from homes and industries
through a 48-km long deep tunnel sewer that runs 20 to 55
meters below ground to a centralized water reclamation plant
for treatment.
