Desalination : GE Says, "Hold
the Salt"
TREVOSE, PA -- GE has joined the
Algerian Government, the Overseas Private Investment
Corporation (OPIC) and the Algerian Energy Company (AEC), in
announcing plans to build Hamma Water Desalination SpA
(Hamma) - Africa’s largest seawater desalination plant.
Formed and funded by GE and AEC,
the Hamma project is part of GE’s ecomagination effort,
which is aimed at building innovative solutions to tough
global problems, like water scarcity. The Hamma project will
supply 25% of Algeria’s capital city’s population with
desperately needed drinking water.
“Many regions of the world face
severe water scarcity, and the issue is getting worse
daily,“ said George Oliver, CEO, GE Infrastructure, Water &
Process Technologies. “The Hamma project is at the forefront
of GE’s ecomagination commitment. We look forward to working
with the Algerian Government on this project that will
create new sources of water for the people of Algiers and
lessen demands currently placed on their limited supply of
fresh, usable water.”
By supplying 200,000 cubic meters
(53 million U.S. gallons) of potable water a day and
reducing energy and overall costs, the build-own-operate
project will lessen Algeria’s water scarcity issues.
Currently, the people of Algeria are plagued with usable
water challenges that range from drinking water shortages
and irregular rainfall to aging infrastructure that can
cause immense losses of water. Because of the scarcity of
clean water, the residents of Algiers only receive water one
out of every three days.
Funded by GE (70%) and AEC (30%),
Hamma will be the first private desalination reverse osmosis
potable water project in Algeria. The project will also be
the largest membrane desalination plant in Africa, as well
as one of the largest desalination plants in the entire
world. OPIC, which helps U.S. businesses invest in new and
emerging overseas markets, also financed $200 million
towards the project.
Construction on Hamma is
scheduled to begin in July 2005 and is estimated to last 24
months. Hamma joins 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.
GE’s largest ecomagination
project and the world’s largest membrane-based water
reclamation facility is the Sulaibiya facility in Kuwait.
This facility purifies municipal wastewater to produce 100
million gallons per day of clean water for industry and
agricultural uses. GE now has an installed base of more than
1,100 water treatment plants that can achieve flow rates
ranging from 30,000 gallons/day to 100 million gallons/day.

New Technology Removes Viruses
From Drinking Water
 Newark,
DE -- University of Delaware researchers have developed an
inexpensive, nonchlorine-based technology that can remove
harmful microorganisms, including viruses, from drinking
water.
UD's patented technology,
developed jointly by researchers in the College of
Agriculture and Natural Resources and the College of
Engineering, incorporates highly reactive iron in the
filtering process to deliver a chemical “knock-out punch” to
a host of notorious pathogens, from E. coli to rotavirus.
The new technology could
dramatically improve the safety of drinking water around the
globe, particularly in developing countries. According to
the World Health Organization (WHO), over a billion
people--one-sixth of the world's population--lack access to
safe water supplies.
“What is unique about our
technology is its ability to remove viruses--the smallest of
the pathogens--from water supplies,” Pei Chiu, an associate
professor in UD's Department of Civil and Environmental
Engineering, said.
Chiu collaborated with Yan Jin, a
professor of environmental soil physics in UD's plant and
soil sciences department, to develop the technology. They
then sought the expertise of virologist Kali Kniel, an
assistant professor in the animal and food sciences
department, who has provided critical assistance with the
testing phase.
“A serious challenge facing the
water treatment industry is how to simultaneously control
microbial pathogens, disinfectants such as chlorine, and
toxic disinfection byproducts in our drinking water, and at
an acceptable cost,” Chiu noted.
“By using elemental iron in the
filtration process, we were able to remove viral agents from
drinking water at very high efficiencies. Of a quarter of a
million particles going in, only a few were going out,” Chiu
noted.
The elemental or “zero-valent”
iron (Fe) used in the technology is widely available as a
byproduct of iron and steel production, and it is
inexpensive, currently costing less than 40 cents a pound
(~$750/ton). Viruses are either chemically inactivated by or
irreversibly adsorbed to the iron, according to the
scientists.
Technology removes 99.999 percent
of viruses.

San Diego Unveils Solar System
at Water Treatment Plant
 SAN
DIEGO, CA -- City of San Diego Mayor Jerry Sanders today
launched a new 1.135 megawatt solar power installation at
San Diego’s Alvarado Water Treatment Plant. The panels
produce about 20 percent of the plant’s power, with annual
electricity savings estimated at $40,000.
The
Alvarado photovoltaic installation was built under a power
purchase agreement (PPA) with SunEdison, North America’s
largest solar services company. Under the agreement, San
Diego citizens benefit from clean, solar energy with no
upfront cost, thereby avoiding an estimated $6.5 million in
capital installation. SunEdison built, owns and will
maintain the solar system. SunEdison will sell the solar
energy to the City’s Water Department at costs lower than
SDG&E rates.
The
1-megawatt water treatment plant site is the first of a
multi-year solar deployment at City facilities that will
eventually produce 5 megawatts of solar power and will
become the largest municipal system in California,
surpassing Google’s planned 1.6 megawatt solar system in
Mountain View, California.
“Installing 5 megawatts of solar panels on City-operated
property is a major step toward meeting the City’s target of
providing 50 megawatts of renewable fueled power generation
by 2013,” said Mayor Sanders.
The
Alvarado installation has 6,128 photovoltaic solar panels
located atop the concrete roofs of all three water storage
reservoirs, a total area covering approximately 4.33 acres.
Each panel measures 4.5x3.5-feet. The solar power system,
with the capacity to produce 1.602 million kilowatt hours of
electricity per year, will have a measurable environmental
impact and will reduce annual carbon emissions equal to 219
cars driving 12,500 miles annually.
As
part of a planned 5 megawatt solar system deployment, the
Alvarado solar array marks another step forward in providing
clean, renewable energy for San Diego, which has been
recognized as the nation’s #1 “Green Power Partnership” city
by the Environmental Protection Agency since 2006. The City
and SunEdison are investigating an additional 4 megawatts of
solar projects at other San Diego sites including the Otay
Water Treatment Facility and the Black Mountain Reservoir.
Mayor
Sanders added, “When the 5 megawatts of solar systems are
fully installed, they will support California’s goal of
increasing the percentage of renewable energy in the state’s
electricity mix to 20 percent by 2017,” he said. “We are
gratified to be able to work with SunEdison to make
predictably-priced clean solar energy available to the
city.”
SunEdison, LLC, is North America’s leading solar energy
service provider. SunEdison provides solar-generated energy
at or below current retail utility rates to a broad and
diverse client base of commercial, municipal and utility
customers.

Mr. Lai needs help with stainless steel containers:
I wanted to ask why stainless
steel is not suitable for FeSO4 (30%). After checking
4 out of 5 chemical charts stating SS316 is definitely out,
but FeSO4 pose no effect on SS304.
However, one charts states
SS304 is not suitable because FeSO4 will cause pits on the
steel. I can't determine whether all SS304 have the
same compositions.
So, my question is, which
element in SS304 and 316 does the SO4 attacks? Can
someone support the statement that SS304 is suitable for
FeSO4 application? (Click
