Grundfos : Purchases Leading
Dosing Pump Manufacturer
 Bjerringbro,
Denmark -- Within the dosing area, Grundfos as well as
Alldos primarily produce motor-driven pumps for dosing of
chemicals for water treatment. Grundfos has only been
involved in this business area for four years, but in spite
of that the Group has managed to develop and introduce some
of the most advanced dosing pumps in the market with its
Digital Dosing concept.
The acquisition of Alldos
provides Grundfos with a strong basis for further growth in
the area through a wider product range with pumps, which
include sensors, disinfection technology, and broader
application knowledge. Furthermore, Alldos has a
well-established sales network.
Group President and CEO, Jens
Jorgen Madsen, Grundfos, made the following statement in
connection with the purchase: "This acquisition is a
consequence of Grundfos' increasingly active acquisition
strategy where we screen the pump market systematically for
relevant purchases to match our strategies. It has been
decisive for us that dosing pumps are Alldos' core business
and that the company has a great amount of know-how within
this market segment. That Alldos is a well-run company, a
strong brand and not least that they prioritize product
development has also been decisive for us. It is all in
keeping with the way we work and I see great opportunities
for synergies in this acquisition."
Alldos has 36 years of experience
in the dosing area, a relatively large development
department, and furthermore the company has a
well-established co-operation with the College of
Engineering in Karlsruhe concerning their development work.
Apart from product development, application knowledge is an
important competitive parameter. In the light of that, the
Grundfos Group has chosen to center its main dosing pump
activities around the newly acquired company.
Executive Vice President, Soren
O. Sorensen, Grundfos, says: "Apart from the water treatment
sector, liquid dosing pumps for the food industry is an
important market segment. We have only recently begun
working with pumps for the food industry when we purchased
another German pump company called Hilge last year, and in
the long run we expect to be able to create synergies
between these two areas."
Apart from dosing pumps and
systems, Alldos develops and manufactures sensors and
control systems for use in connection with dosing pumps.
Commenting on this, Mr Soren O. Sorensen says: "Sensors and
control systems constitute a new and extremely interesting
area to us, with a large potential as these products form
part of most dosing installations"
The former owner of Alldos, BSc
(Engineering) Wolfgang Eichler, will retire from his
position as chairman of the board when Grundfos takes over.
Mr Sorensen from Grundfos will take up the post.
Mr. Eichler made the following
comment to the sale: "Finding a buyer with global impact,
focus on development of basic technologies and strong values
has been crucial to me. In that respect, I am convinced that
Grundfos is the best possible buyer. The fact that Alldos
will become a competence center for Grundfos Dosing is of
course a great pleasure. It means that the knowledge that my
competent staff has gathered over the years is passed on to
the new owners in the best possible way, thus creating basis
for continuous growth in future."
Mr Sorensen adds, "With this
acquisition, we wish to create a competence center for
dosing pumps based at Alldos.
The acquisition further
strengthens our platform for development and increases our
possibilities for synergy between our dosing pumps and a
wide range of our other pump products," This is the first
time Grundfos establishes a large product development center
outside Denmark.

Desalination : New Technology
Taps Waste Heat
 GAINESVILLE,
FL --- Desalination is often touted as one solution to the
world’s water woes, but current desalination plants tend to
hog energy.
Now
University of Florida researchers have developed a
technology that can tap waste heat from electrical power
plants as its main source of energy, an advance that could
significantly reduce the cost of desalination in some parts
of the world.
“In
the future, we have to go to desalination, because the
freshwater supply at the moment can just barely meet the
demands of our growing population,” said James Klausner, a
UF professor of mechanical and aerospace engineering, whose
research was funded by the U.S. Department of Energy. “We
think this technology could run off excess heat from utility
plants and produce millions of gallons each day,” said
Klausner, lead author of an article on the system that
appears in the current issue of the Journal of Energy
Resources Technology. He co-invented the technology with
fellow UF mechanical engineering professor Renwei Mei.
Most
commercial desalination plants now use either distillation
or reverse osmosis, Klausner said. Distillation involves
boiling and evaporating salt water and then condensing the
vapor to produce fresh water. In reverse osmosis, high
pressure pumps force salt water through fine filters that
trap and remove waterborne salts and minerals.
Boiling the vast amounts of water needed for the
distillation process requires large amounts of energy.
Reverse osmosis uses less energy but has other problems,
including mineral buildup clogging the filters. That’s the
main technical issue plaguing the largest desalination plant
in the United States, Tampa Bay Water’s $108 million plant
in Apollo Beach. Although it was supposed to produce 25
million gallons of freshwater each day, the plant, beset by
technical and financial problems since opening in 1999,
currently is shut down.
Employing a major modification to distillation, Klausner’s
technology relies on a physical process known as mass
diffusion, rather than heat, to evaporate salt water.
In a
nutshell, pumps move salt water through a heater and spray
it into the top of a diffusion tower – a column packed with
a polyethylene matrix that creates a large surface area for
the water to flow across as it falls. Other pumps at the
bottom of the tower blow warm, dry air up the column in the
opposite direction of the flowing water. As the trickling
salt water meets the warm dry air, evaporation occurs.
Blowers push the now-saturated air into a condenser, the
first stage in a process that forces the moisture to
condense as fresh water.
Klausner said the key feature of his system is that it can
tap warmed water plants have used to cool their machines to
heat the salt water intended for desalination, turning a
waste product into a useful one.
He has
successfully tested a small experimental prototype in his
lab, producing about 500 gallons of fresh water daily. His
calculations show that a larger version, tapping the waste
coolant water from a typically sized 100-megawatt power
plant, has the potential to produce 1.5 million gallons
daily. The cost is projected at $2.50 per 1,000 gallons,
compared with $10 per thousand gallons for conventional
distillation and $3 per thousand gallons for reverse
osmosis.
Because the equipment would have to extract as much heat as
possible from the coolant water, it would need to be
installed when a plant is built, he said. Another potential
caveat is that a full-scale version of the mechanism would
require a football field-sized plot on land, likely to be
expensive in coastal areas where power plants are located,
Klausner said. Presumably a utility would sell the fresh
water it produces, recouping and then profiting from its
investment, he said.
Klausner said a miniature version of the full-scale system
could be run using solar or other forms of heat, which might
be useful for small towns or villages. UF has applied for a
patent on the technology. Klausner’s research was funded by
a $200,000 grant from the Department of Energy.

EPA : Agencies Sign Watershed
Management Agreement
 Washington,
DC -- The U.S. Environmental Protection Agency’s Office of
Water and the U.S. Army’s Office of the Assistant Secretary
of the Army for Civil Works have entered into an agreement
to establish a collaborative watershed partnership. The
Corps of Engineers attempts to balance competing demands on
the nation’s critical water resources through flood control,
navigation, recreation, and infrastructure and environmental
stewardship. EPA seeks to ensure drinking water is safe, and
to restore and maintain the nation’s aquatic resources for
human health, to support economic and recreational
activities, and to provide healthy habitat for fish, plants
and wildlife.
Acting Assistant Administrator for Water Ben Grumbles and
Assistant Secretary of the Army for Civil Works John Paul
Woodley, Jr., signed the partnership agreement.
“This
partnership with the U.S. Army Corps of Engineers will
foster innovative approaches to finding effective answers to
the many challenges and demands facing the nation’s
watersheds today and in the future,” said Grumbles.
“Managing water resources on a holistic watershed basis
makes good sense – environmentally, financially and
socially. This agreement will enable EPA and the Corps to
work together to try to resolve conflicts and seek consensus
among the many different interests within a watershed
concerning the future of these critical national resources.”
Woodley also praised the agreement: "This partnership
agreement is a great example of the benefits that can be
created when federal agencies come together to work toward a
common goal and share a common vision. By combining the
organizational strengths and capabilities of the Corps and
EPA's Office of Water as they relate to watershed health and
management, we create a win-win partnership for the agencies
and the nation."
The
agreement signed on Nov. 19 focuses on facilitating
sustainable economic development, protection, and
restoration efforts in a public, inclusive and collaborative
manner at the national, regional and local watershed level.
Other objectives include facilitating communication among
all stakeholders and interested parties, enhancing data
exchange and promoting the development of innovative
approaches to water resource and watershed management.

USFilter : Underdrain Filter Design Re-Engineered
 WARRENDALE,
PA -- USFilter has re-engineered its MULTICRETE II (TM)
monolithic concrete filter underdrain system used in water
and wastewater filters. The new design increases the
underdrain system's strength and simplifies the
installation process.
The NSF Standard 61-approved
underdrain can weather the harshest downward and upward
pressures subjected during years of filtration and
backwash. To ensure the underdrain is capable of resisting
higher pressures and better handling of cyclic loading,
the underdrain form was re-engineered to increase
allowable floor thickness. The forms support loads from
installation traffic and wet concrete while minimizing
deflecting to less than one-eighth of an inch. Based on
filter system requirements, the underdrain can be designed
for a range of downward and uplift loads. Standard system
design meets the structural requirements of ACI 318
standards.
To simplify installation, the
false-floor underdrain consists of plastic form work used
to support concrete and reinforcing rebar during the
installation process. Underdrain nozzles, installed after
the concrete is cured, collect filtered effluent and
distribute water and air during backwash. In addition, a
unique fastening system has been developed to allow a
simple one-quarter turn rotation to secure the inserts in
place saving installation labor and improving quality
control during installation.
While the underdrain system has
been improved to benefit installers and plant owners, the
working performance remains the same as the previous
designs. MULTICRETE II underdrains have been in use at
hundreds of water and wastewater filters for nearly 20
years.
USFilter Corporation, a Siemens
company, delivers cost-effective, reliable water and
wastewater treatment systems and services to municipal,
industrial, commercial and institutional customers
worldwide. USFilter is part of Siemens' Industrial
Solutions and Services Group (I&S), which provides
innovative solutions and services designed to improve
competitiveness in processing and manufacturing industries
and in infrastructure. In fiscal 2003 (to September 30)
I&S employed a total of 25,000 people worldwide and
achieved total sales of USD $4 billion (EUR 4.012
billion). Visit company websites at

Mr. Bethel
has questions about chemical usage:
I have a two-part question.
My first question is, I need to know how to figure how
much Sodium Thiosulfate to add to a basin to reduce the
Chlorine level. Example, If I have a 8,500 gallon basin
with a Free Chlorine reading of 13.00 mg/l and what to
reduce it down to a 2.00 mg/l level.
My second question is I need
to know how to figure how much Hydrogen Peroxide to add to a
basin to remove the pink color of the water from to much
Potassium Permanganate being added.

Mr. Kasberg
needs help with ammonia:
I have an NPDES permit limit
on ammonia on a small extended aeration package plant.
Domestic sewage only, that is typically under loaded.
Effluent Limits are:
1.5 mg/l summer
4.5 mg/l winter
I have read that extended
aeration plants do not effectively remove ammonia. (May be
hard to control). I am having trouble getting ammonia down
to limit (fluctuates between 5 and 15 mg/l)
Anyone have any suggestions
for better ammonia removal ??
