Hi Everyone,
First I want to say sorry about last
week's issue, there was none. I do have a good excuse, I was
at the WEFTEC meeting in Atlanta and it was great! Got a
chance to catch up with some old friends and meet plenty of new
ones.
There were between 900 to 1,000
companies displaying their "wares" from all walks of the
water treatment world. Good crowds, though some exhibitors
noticed a smaller number of overseas visitors this year.
Overall, those at the show, both exhibitors and visitors, were in
good spirits and looking forward to a busy year.
If you missed the show, you missed a
good one. You can learn more about the WEFTEC and the Water
Environment Federation at their web site: http://www.wef.org
.
Now that my feet have recovered and
I'm back in the office, I look forward to a great year. We
hope you will have one too.

SAN ANTONIO, TX USA 07/31/2001 SAN
ANTONIO, Oct. 9 /PRNewswire/ -- The health risks associated with
sludge byproducts have raised concerns among the public forcing the
government to take a proactive role in tightening and enforcing
environmental regulations. Social awareness and cost-constraints are
also driving the industry in new and positive directions.
New
analysis from Frost & Sullivan (http://environmental.frost.com/),
U.S. Sludge Treatment Equipment Markets, reveals that this industry
generated revenues of $294 million in 2000 and is projected to
increase steadily to $363 million by 2007.
"Wastewater treatment plant
operators are more interested in sludge handling equipment since
this aspect of the process consumes upwards of 30 percent of plant
operating budgets," says Frost & Sullivan Industry Analyst
Linda Chaloux. "In previous operations, facility participants
were concerned with finding the quickest and least expensive route
for sludge disposal. Now the industry is embracing a more holistic
approach."
Equipment must not only be economical
but must also accommodate the type of byproduct that will be least
harmful to the environment. As public interest continues to mount,
municipalities are expected to drive sales as they work to allay
end-users' concerns.
"Public perception of the risks
associated with sludge is the number one driver for the sale of
sludge equipment that can produce Class A 'exceptional quality' (EQ)
biosolids," says Chaloux. "In various parts of the country
there has been a public outcry and outrageous concern that Class B
biosolids are dangerous and must be kept as far away as possible
from human contact."
Supporting this public rally are
increasingly stringent government regulations. Local governments
will have to perform retrofits and expansions in response to
increasing population levels as well as the rising need to
accommodate alternative methods of treating sludge to satisfy
regulatory requirements and community apprehension.
"As with most types of
wastewater treatment equipment, government regulations are among the
most significant factors influencing the sludge equipment
markets," says Chaloux. "With requirements becoming
stricter, treatment equipment will need to be installed, replaced,
or retrofitted."
Frost & Sullivan presents the
2001 Marketing Engineering Awards to companies that have worked
diligently to make a positive contribution to the sludge treatment
equipment industry. These market specific awards are presented to:
Ashbrook, Bioset Corporation, and U.S. Filter Dewatering Services
Group.

"Evolutionary"
Haestad Announces "Darwin"
Optimizer
WATERBURY, CT, USA-October 15,
2001-Haestad Methods today announced the development of Darwin, a
revolutionary new software program for water resources modeling
based on an advanced hybrid form of Genetic Algorithms (GA).
Darwin,
the first software of its kind in the industry, evolves new
generations of "fitter" solutions, essentially mimicking
the natural selection process while accepting intervention from the
user. Haestad Methods' engineers, including GA optimization pioneer
Dr. Zheng Yi Wu and modeling expert Dr. Tom Walski, lead this
development.
Harnessing the power of its
"evolutionary" technology, Darwin provides the speed and
flexibility to evaluate billions of parameter combinations in an
incredibly short time, enabling optimal designs, model calibrations,
and operational strategies to surface in just seconds. Darwin allows
engineers to complete tasks with a level of accuracy previously not
possible with strictly human-controlled iterations, even using the
world's fastest computers.
Darwin's impact on the modeling
community will soon be felt as users apply its methods to their
stormwater conveyance systems and water and sewer networks.
"Engineers can utilize Darwin's sophisticated GA features for
practical applications--including, determining the most
cost-effective design of conveyance systems in StormCAD; scheduling
of pumps, model calibrations, and design optimizations in WaterCAD;
and rehabilitation and design of sanitary collection systems in
SewerCAD," said Dr. Zheng Wu, Lead Software Developer for
Haestad Methods.
Overview
Darwin earns its name from its
"survival of the fittest" approach to problem solving. It
begins with a group of possible solutions and evaluates each one
based on how closely it fits the desired conditions. The fittest
solutions are used as the starting point for the next generation of
solutions, with changes/mutations entering the mix as better
solutions evolve.
The process continues until the
optimum solution is found (i.e., the solutions stop improving from
one generation to the next). Human intervention and guidance can be
applied before and during the process through a "hot
start" facility.
"There has been a lot of
research on the application of optimization methods to water
resources problems," said Dr. Walski, Vice President of
Engineering at Haestad Methods. "However, past GA work did not
lead to wide acceptance of GA optimization in engineering practice
primarily because it did not capture the essence of the engineering
decision-making process. With Darwin, we have enabled human judgment
and turned theoretical GA research into practical software for the
engineer."
Darwin as a Calibrator
Manually adjusting system demands and
fine-tuning pipe roughness is a huge time investment, even for the
most experienced engineer. By automating this process with Darwin,
the engineer can expedite the calibration process by orders of
magnitude while supervising and managing the process through simple
interfaces. Darwin can take a field pressure and flow measurements
and determine pipe characteristics and water use.
"No amount of human experience
using today's computers could realistically evaluate this many
iterations," said Dr. Wu. "By combining the results from a
GA with sound engineering judgment, Darwin can arrive at a true
optimal solution."

Security
of Drinking Water
AWWA Calls Terrorist
Threats "Remote"
Water Utilities Have Nevertheless
Heightened Security Measures
(Denver, Colorado) - The American
Water Works Association, an organization that represents America's
water treatment utilities and drinking water professionals, joins
U.S. Environmental Protection Agency Administrator Christine Todd
Whitman in assuring the public that the nation's drinking water is
safe and highly unlikely to be compromised in the event of a
terrorist attack. Ms. Whitman spoke today about potential threats to
the nation's water supply at a press conference in the Washington,
D.C., area. (For more information, see: http://www.epa.gov/epahome/newsroom.htm)
"As
Ms. Whitman pointed out, water utilities have long taken extensive
precautions to prevent against a threat to the security of public
drinking water," said AWWA Executive Director Jack Hoffbuhr.
"But that doesn't mean utilities should be complacent, and they
are not. Indeed, water utilities large and small and in every part
of the U.S. have further heightened their security systems and
procedures since the deadly and devastating terrorist attacks of
September 11."
Hoffbuhr pointed out that many highly
effective safeguards have long been and remain in place to detect
and eliminate harmful toxins. As for anthrax specifically,
filtration is effective at removing it from drinking water.
"Water is an especially poor delivery system for anthrax,"
Hoffbuhr said.
He added it would take enormous
quantities of most potentially harmful chemical agents to
successfully compromise a water system. "Most systems have so
much water and such effective treatment mechanisms, that anything
less than many tankers full of dangerous agents would be diluted and
easily neutralized. It is hard to imagine that anyone would have the
ability to deliver such quantities effectively and without
detection."
Water utilities, Hoffbuhr noted, have
long been vigilant about and prepared for security encroachments.
But since September 11, they have been on heightened alert and put
significant additional security safeguards in place. Many are:
Limiting access within and
throughout utility treatment and storage facilities.
Meeting shipments at their gates
and escorting them with security personnel to the plant.
Conducting additional testing and
monitoring of chemical agents delivered to the plant before they
are introduced into the treatment system.
Reassessing procedures and systems
that are in place to detect security incursions.
Providing additional training to
their personnel to be alert to and to recognize the signs of a
potential threat.
For its part, AWWA reissued materials
on terrorism and emergency preparedness to its members and has
continued to provide additional security information, resources, and
training to all of America's water professionals. AWWA has also
developed a series of water utility security training workshops and
will be offering them to water professionals within the next month.
AWWA Research Foundation has developed vulnerability assessment
tools and will be working with member utilities and the EPA to
provide this tool to utilities. Information on how to become a
member of AWWA is available at our website at www.awwa.org.
"Local water utilities are also
prepared with plans to inform the public immediately in the event of
any sort of emergency that would affect the water supply",
Hoffbuhr said. "These plans have been effective in the past for
natural disasters and other local events."
"While water utilities today are
well-equipped to protect the public against threats to their
drinking water," Hoffbuhr said, "important consideration
must be given to the long-term, general security and well-being of
the nation's drinking water infrastructure. Much needs to be done
over the next several decades to replace an aging infrastructure and
that must meet the demands of a growing population."
The American Water Works Association
and its 57,000 members work to assure a safe, sufficient supply of
drinking water for the people of the United States, Canada, and
Mexico. The group leads efforts to advance the science, technology,
consumer awareness, management, conservation, and government
policies related to drinking water. For additional information
