ASCE : Calls for New Orleans
Advisory Panel
Reston,
VA -- The American Society of Civil Engineers (ASCE) today
called for the creation of an independent, federally funded
reconstruction advisory panel for New Orleans to serve as
the primary advisor to local officials on the rebuilding of
the city and immediate surrounding areas. The panel should
be comprised of technical experts who would provide an
objective review of all design and construction issues
relating to the reconstruction and would be fully integrated
with any federal agency involved in these efforts.
As proposed, the New Orleans
Reconstruction Advisory Panel charter would be as follows:
The federally sponsored and
funded advisory panel will serve as primary advisor to the
Mayor of New Orleans and affected parish, city and state
governments on the rebuilding of the city;
-
The panel will consist of experts from engineering,
architecture, planning and other design and construction
related fields;
-
The recommendations of the panel will include strategies
to minimize the impact of future storm events and other
hazards;
-
The primary goal will be to maintain and improve the way
of life for the citizens of the metropolitan New Orleans
area;
-
The focus of the panel will be on incorporating
mitigative and sustainable measures into the
reconstruction efforts;
-
The panel will serve as link to federal agencies working
in support of the reconstruction effort; and
-
The panel will function in an advisory capacity only and
will have no authority to mandate solutions.
The panel concept was developed
with leading non-governmental organizations at a meeting
held on September 6 in Washington, D.C. Sponsored by ASCE
and The Infrastructure Security Partnership, the roundtable
meeting was held to coordinate a unified response by the
engineering, design and construction community to the
devastation caused by Hurricane Katrina.
The Infrastructure Security
Partnership (TISP) was established following the tragic
events of September 11, 2001 as a forum for U.S.-based
public and private sector non-profit organizations to
collaborate on issues regarding the security of the nation's
built environment, including resilience to natural and
man-made disasters through effective and efficient planning,
design, construction and operation. Membership includes more
than 200 organizations and agencies representing more than 2
million individuals and firms.
Founded in 1852, ASCE represents
more than 137,000 civil engineers worldwide and is America's
oldest national engineering society. The society celebrated
its 150th anniversary in 2002.

Hurricane Relief : ITT Offers
Funds and Equipment
White
Plains, NY -- ITT Industries has pledged $250,000 to the Red
Cross to fund immediate hurricane relief, and has made
available fluid technology equipment for delivery to
Louisiana, Mississippi and Alabama, including dewatering
pumps and reverse osmosis systems which could be vital to
relief efforts. Additionally, the company has sent night
vision equipment and personnel to assist in round-the-clock
search and rescue efforts in the affected areas.
“ITT
Industries is ready to offer our technical experience and
equipment to provide emergency relief to the areas most
impacted by Hurricane Katrina,” said Steve Loranger,
Chairman, President and CEO of ITT Industries. “Removing the
flood waters from New Orleans is a vital preliminary step to
planning for recovery in that region. We’re prepared right
now, to provide our equipment and expertise as well as water
treatment equipment, wherever and whenever it is needed.”
ITT
has installed more than 70 large turbine pumps in New
Orleans over the years as part of the city’s flood control
system. Together, these pumps are capable of pumping up to 2
billion gallons an hour. To supplement these in the
hurricane’s aftermath, ITT has prepared a fleet of more than
100 large submersible pumps, routinely rented for dewatering
projects, on standby to help remove the flood waters from
New Orleans. Developed just prior to the “Great Midwest
Flood of 1993,” these engine-driven pumps can each remove
20,000 gallons of water per minute. The company has also
readied numerous smaller units capable of pumping between
100 and 15,000 gallons of water per minute.
Additionally, ITT has prepared chlorination and UV
disinfection equipment to help provide potable water to
victims of Hurricane Katrina. This equipment can provide up
to 250,000 gallons of water per day. The company provided
similar systems to Iraq and following the tsunami in Sri
Lanka to provide clean drinking water for thousands of
people.
ITT
night vision equipment and training personnel are already in
Louisiana, enabling searches to continue around the clock.
The company donated 22 night vision goggles to police
agencies, and has offered training in mission applications.
Further, ITT imagers are providing real time satellite
imagery to rescue and relief operations.

USFilter : Multiwash System
Ordered for Albuquerque
WARRENDALE,
PA -- The city of Albuquerque, N.M., has awarded USFilter, a
part of Siemens Water Technologies, the contract to supply a
filter system for the city’s new 92 million gallon per day
(mgd) drinking water treatment facility. USFilter was
selected to supply the filter underdrain, washtroughs, and
granular activated carbon (GAC) media valued at
approximately $2.5 million. The project was driven by the
need to improve surface water quality by addressing taste
and odor issues.
The
filtration system consists of 12 filter cells for a total of
12,480 sq.ft. USFilter's direct retention Multicrete II™
underdrain system will support a 72-inch depth of AquaCarb®
granular activated carbon and 12 inches of filter sand.
Corrosion resistant plastic components are used in the
entire underdrain system.
Collection of backwash waste will be provided with 72 ESSD™
type 316 stainless steel washtroughs equipped with patented
Low Profile Multiwash® separator baffles. Selection of the
Multiwash separator system was based on proven experience to
retain GAC media at other large full-scale installations.
"We
reviewed several filtration options for this project,"
comments CH2M Hill engineer Brock McEwen. "The proven track
record of the Multiwash system with GAC media lead us to
select it as the basis of design."
The
combination of Multicrete II underdrains and Multiwash
baffled washtroughs are in operation at hundreds of
installations including lime softening, iron and manganese
removal, surface water treatment and wastewater filtration.
The open plenum underdrain system uniformly distributes air
and water during backwash for powerful cleaning efficiency.
Multiwash baffles allow combined air-water backwashing while
overflowing the washtroughs and minimize the separation
between media and washtroughs. Backwash waste volume and
cycle time are reduced while guaranteed media cleanliness
and media loss prevention is provided. Systems in operation
include single and multi-media beds including several large
installations with GAC media.
The
AquaCarb® granular activated carbon is ANSI/NSF Standard
61-classified for use in potable water applications. The
carbon is manufactured by USFilter Westates Carbon from
selected grades of bituminous coal. The carbon adsorbs
dissolved organics, taste and odor compounds.
The
plant was designed by CH2M Hill of Albuquerque, N.M., and
will be installed by PCL/Triad Joint Venture of Albuquerque.
The plant is scheduled to be operational by June of 2007.

GE : Plays Critical Role in 78 MGD Ultrafiltration Plant
TREVOSE,
PA -- GE Infrastructure, Water & Process Technologies, a
unit of General Electric Company, joined the City of
Minneapolis today for the opening tour of the city's new
Columbia Heights water filtration plant - the world's
largest potable ultrafiltration (UF) plant. The plant
utilizes GE's UF solutions to provide up to 78 million
gallons per day (MGD) of potable water to over half a
million Minneapolis residents.
Cryptosporidium is a
waterborne protozoa that is harmful for humans to ingest
and can cause symptoms that include fever, weight loss,
dehydration, vomiting, and death. In 1993, Milwaukee
battled a Cryptosporidium outbreak that claimed the
lives of an estimated 100 residents. The Milwaukee
outbreak prompted the Minneapolis Water Works to conduct
a feasibility study that examined the city's risk
factors, as well as remedies, possible solutions and
technologies that would help safeguard the city's water.
Upon completion of the study, Minneapolis, with its Peer
Review Panel and Citizens Advisory Committee, determined
that GE's UF technology was best-suited to aid the city
in protecting its citizens.
GE's UF technology is a
pressure-driven technology that provides a physical
barrier to pathogens and is commonly used to remove
suspended solids, bacteria, microorganisms, and viruses
in potable water production. The Minneapolis plant
combines GE's UF technology with NORIT membrane
technology - creating a complementary system that
results in the extremely effective removal of hazardous
waterborne microorganisms and contaminants. The
nationally recognized California Department of Health
Services gave ultrafiltration the highest removal rate
credits available.
GE's UF solutions are capable
of delivering the following: consistent, superior water
quality regardless of feed quality variations; dead-end
operation resulting in low energy consumption; greater
than 6 log (99.9999%) removal of Cryptosporidium and
Giardia lamblia; highest certified removal of viruses -
4 log (99.99%); low chemical consumption; permeate
SDI(15) less than 3; small system footprint and compact
arrangement; and proven membrane life.
In addition to the opening of
the City of Minneapolis' Columbia Heights plant, GE was
recently awarded a contract by the City of Mankato, MN
to provide ultrafiltration technology in upgrades to
their water treatment plant. The Mankato plant, which
will provide 12 MGD of potable water to city residents,
will be the state's second largest UF plant and is
expected to be on-line in September 2006.
The City of Minneapolis and
City of Mankato plants will join GE's expanding
ecomagination and water scarcity solutions portfolio,
which includes a wide-range of customized water
solutions designed to create new sources of usable water
for the potable, industrial and agricultural sectors --
while lessening impacts on fresh water sources.

ultrafiltration technology and GE's water scarcity
solutions, please visit

Mr. Hallberg needs help with activated sludge:
I am currently considering
pure oxygen upgrade for our activated sludge plant, my
questions are as follows;
- What determines the
maximum oxygen uptake of the microorganisms?
I must assume that it depends partly on how much CO2
that is generated from the biomass.
- There must be a
situation where a balance between partial pressure of
oxygen and partial pressure of CO2 in the system exists.
At what pressures would those be?
- What is the discharge
rate of CO2 from the surface compared to oxygen?
- Should the system be
shallow and wide or deep and narrow?
What I am questioning is,
there may be a limit to how much biomass can exist in the
system based on how much oxygen can be consumed, depending
on many factors one being CO2 discharge. Can anyone
advise on real plant situation behaviour?
