WERF Publishes Biological
Phosphorus Removal Study
 OMAHA,
NE -- The Water Environment Research Foundation (WERF)
recently published results of a study completed by HDR
examining the reliability of enhanced biological phosphorus
removal (EBPR) in removing phosphorus to low levels in
wastewater effluent. The goal of the research project was to
develop information that can be used to help municipal
wastewater treatment plants more efficiently and
cost-effectively remove phosphorus through EBPR processes.
The project included detailed
analysis of routine water quality and operating data, field
testing observations, and special studies conducted over the
course of the project to evaluate the variability of EBPR,
factors influencing EBPR performance, and the relationship
between EBPR and the presence of glycogen accumulating
organisms (GAOs).
The study showed that EBPR is
capable of achieving very low effluent phosphate
concentrations. When operating well, it is possible to
achieve soluble phosphate concentrations under 0.1 mg/L.
However, many facilities struggle to routinely achieve
soluble phosphate concentrations under 1.0 mg/L. For this
reason, most facilities experience significant variability
in EBPR performance, requiring augmentation of EBPR through
the use of substrate addition or polishing with iron- or
aluminum-containing chemicals. Contributing HDR authors are
JB Neethling, Ph.D., P.E., DEE, Brian Bakke, P.E., Mario
Benisch, April Gu, Ph.D, and Heather Stephens, P.E.
The 431-page report is available
for purchase from www.werf.org.
The cost is $10 to subscribers; suggested retail is $175.

Siemens Announces Agreement with
US Peroxide
 Warrendale,
PA -- Siemens is expanding its full service odor control
capabilities through a new license agreement with US
Peroxide, LLC., Laguna Niguel, Calif.
This
strategic joint market development agreement with US Filter
Corporation, Warrendale/PA, a company of the Siemens Group
Industrial Solutions and Services (I&S), will allow Siemens
to incorporate US Peroxide's patented PRI-SCtechnology into
its Davis Process full service odor control program.
PRI-SC
(Peroxide Regenerated Iron-Sulfide Control) is a combination
treatment that integrates iron salts with hydrogen peroxide
(H2O2) in a synergistic fashion. The combined treatment
provides cost and performance benefits superior to either
chemical alone, while allowing greater flexibility as to the
placement of storage and dosing facilities.
USFilter sought out the unique PRI-SC process because it
offers an efficient and cost competitive alternative to main
system, trunk, and sewer line odor and corrosion control.
USFilter's full service odor control approach is based on
matching the best odor control technology for a given
application, depending on performance, economics, safety,
and process impact.
"We
are excited to be able to offer this technology with the
increasing demand for enhanced odor control. This provides
many municipalities another advanced technology to improve
their system's performance and stretch their odor control
budgets," said USFilter's David Hunniford, vice president
and general manager, Davis Process products and services.

Arcadis Awarded Design of WWTP
in North Carolina
 DENVER,
CO -- Arcadis announced today that it has been selected to
provide engineering design services for the new 18 million
gallons per day (MGD) Western Wake Regional Water
Reclamation Facility in western Wake County, North Carolina.
Wake County is home to North Carolina's Research Triangle
Park where the cities of Raleigh, Chapel Hill, and Durham
have attracted thousands of people for its universities,
high-tech laboratories, corporate headquarters and
lifestyle.
Decades of regional growth combined with evolving regulatory
requirements and pressure to provide cost-effective services
while protecting the community's quality of life have
presented the towns of Apex, Cary and Morrisville with a
challenge: to responsibly provide long-term economical
wastewater management solutions. As a result, Arcadis will
design and build a regional wastewater treatment facility to
provide the necessary capacity and comply with the terms of
the Interbasin Transfer agreement. The design award is worth
$9 million in fees.
To
oversee the regional solution, the Western Wake Partners
were formed for which the Town of Cary serves as the lead
agency responsible for design, construction, operation and
maintenance of the first regional greenfield water
reclamation facility of this scale in North Carolina.
"The
selection of Arcadis for this critical project reinforces
our position as the premier water and advanced wastewater
treatment solutions provider in the state, as well as
nationally and globally," said Bryan Mulqueen, senior vice
president and North Carolina State manager for Arcadis.
Mulqueen said the design is scheduled to be completed in 16
months and the plant will go online in 2010. "The plant
design is for 18 MGD and is expandable to 30 MGD."
The
Arcadis team is responsible for designing a state-of-the-art
facility including biological nutrient removal,
disinfection, biosolids treatment, administration and
maintenance facilities, related site improvements, and all
ancillary and support facilities. Arcadis designed a
wastewater treatment plant in Cary in the mid-1990s that has
demonstrated superior treatment performance.
Arcadis is a global network of business professionals that
provides project management, consultancy and engineering
services to enhance mobility, sustainability and quality of
life. Arcadis develops, designs, implements, maintains and
operates projects for companies and governments. With 10,000
employees and $1 billion in gross revenue the company is
multi-nationally present with a close-knit local network.
Expertise and experience are of international significance.
We are focused on providing added value to clients.
For
more information contact John Maynard, project manager at
Arcadis, at 919-854-1282 or

Mr. Jurjevic wants to
de-chlorinate wastewater:
My company has process waste
water that must be de-chlorinated before it is released to
surface waters. It is generated in batch sizes of 20 gallons
and contains 600 ppm chlorine.
What would be the best way to
get rid of the chlorine and where can I find info on the
process or equipment to do it?

Mr. Poonam needs help with dosing pumps:
I'm actually getting lots of
problems with my aluminum dosing pump; clogging, and
diaphragm breaking. I'm using my water pump for rapid mixing
to enable coagulation after addition of aluminum sulphate.
The dosing pump is used to
inject aluminum on the aspiration of the water pump. Another
problem I'm getting here is that aluminum is being sucked
into my water pump even though my dosing pump is off.
In the water and wastewater
newsletter, I read about a Watson-Marlow Bredel's 323
Peristaltic Pump which doesn't use a diaphragm. So this
would end my problem of diaphragm. But what about the
problem of suction. My dosing pump should be able to combat
the suction and pump aluminum only when it is put on and
that too accurately, that is just the amount set.
I badly need your help to
find suppliers of such pumps.
