Reactor Recycles WW Nutrients
into Fertilizer
 EDMONTON,
ALBERTA -- The City of Edmonton's Gold Bar wastewater
treatment plant has met a milestone by successfully
operating for over six months as the world's first
industrial-size nutrient treatment facility to remove
phosphorus and other nutrients from municipal biosolids and
recycle them into environmentally-safe commercial
fertilizer.
The technology, developed by
Ostara Nutrient Recovery Technologies Inc. of Vancouver,
will help Gold Bar achieve its nutrient removal goals,
increase plant capacity and reduce maintenance costs, while
also creating a revenue-producing product in the form of a
high value fertilizer.
"Since the Ostara reactor was
commissioned last spring, it has extracted more than 80 per
cent of the phosphorus on average - achieving the design
objective of 75 per cent - and 10 to 15 per cent of the
ammonia from a flow of 500,000 liters per day, approximately
20 per cent of the Gold Bar plant's liquid biosolids
stream," said Vince Corkery, Director of Wastewater
Treatment at the City of Edmonton's Gold Bar treatment
facility.
"We have worked closely with
Ostara over the past two years toward building this
first-of-its kind commercial scale nutrient recovery
facility and we are very pleased with the operating
results," said Corkery.
"We have supported this
technology because it creates a valuable product from
phosphorus and other polluting nutrients, which would
otherwise clog our pipes and reduce our plant's treatment
capacity. We look forward to continued cooperation with
Ostara to add reactors capable of treating 100 per cent of
our biosolids stream in the future," said Corkery.
Phillip Abrary, President and CEO
of Ostara, said, "the Edmonton plant is Ostara's first
commercial-size reactor, however several other commercial
facilities are already in planning and design stages after
successful field trials in 2007 by municipalities, ethanol
biofuel plants and food processing plants in the United
States and Canada. As many as 400 municipalities and
industrial plants in North America and 500 in Europe are
potential customers for the Ostara process."
"Many wastewater treatment
plants, such as Gold Bar, remove phosphorus and other
pollutants from waste waters to reduce their nutrient
loading on the receiving water environment. These nutrients
are extracted from the processes in the form of biosolids.
The biosolids are further dewatered. The nutrient rich
liquid extracted from these biosolids can add costs to the
system by clogging pipes with a concrete-like scale called
struvite the result of phosphorus and ammonia (nitrogen)
combining with magnesium and by occupying up to 25 - 50 per
cent of the system's capacity. The Ostara process treats
these liquids.
"Our reactor integrates into the
wastewater treatment system, processes the biosolids liquids
to recover phosphorus and other nutrients - and then
converts them into a high-quality environmentally-friendly
commercial fertilizer that can generate revenue for the
municipality," said Abrary.
The Ostara reactor at Gold Bar
produces approximately 500 kg of "Crystal Green" fertilizer
per day. The product is sorted, dried and bagged on site and
is immediately ready for commercial sale. No further
processing is required, although for some applications,
fertilizer distributors may wish to blend Crystal Green with
other fertilizer components to match the agronomic needs of
the crop.

Grundfos Acquires Peerless Pump
Company
 Denmark
-- Effective December 1st 2007, the Grundfos Group, with
Headquarters in Denmark has acquired Peerless Pump Company.
Peerless is a US based manufacturer of pumps and fire
protection systems. With more than 400 employees and annual
sales of USD 110 million, Peerless is Grundfos’ largest
acquisition to date. Grundfos continues its aggressive
growth strategy in North America.
Carsten Bjerg, Group President
and CEO of Grundfos Group, comments, "Recently we have
focused on growing our business globally, especially in
Eastern Europe, Asia and North America. The US market has a
significant growth potential and seen in that perspective
the acquisition of Peerless is of great strategic importance
to Grundfos. Combined with the continued expansion of our
R&D facilities and production capacity in North America,
this acquisition is crucial to strengthening our US market
position.”
Today, Grundfos’ sales in North
America are USD 300m. The US pump market alone is estimated
to be USD 6bn, so the business potential for Grundfos is
huge. With the latest acquisition, Grundfos expects to
double sales within a four year period reaching USD 600m.
Soren Sorensen, Group Executive
Vice President and Chairman of the Board of Grundfos in
North America, said, “Grundfos has had a presence in the US
market since 1973 and over the last three years we have made
a series of major investments in North America to accelerate
our growth. With the acquisition of Peerless we extend our
product range as well as our US sales organization
significantly. We expect a lot from this deal and see great
potential for globalization especially of the Peerless fire
protection systems.”
Peerless’ products are high-end
and the company is considered one of the two most recognized
water pump brands in the U.S. according to a 2007 survey
conducted by the US based Pumps and Systems Magazine. All
members of the “Fortune 10” have purchased pumps from
Peerless.
Dean E. Douglas, President and
Chief Executive Officer of Peerless, commented, “We see
Grundfos’ acquisition of Peerless as an extremely positive
move for our customers as well as for the future security
and continued development of our employees, of Peerless Pump
itself, and our world wide sales network. The synergies
between our organizations are significant and will allow
Peerless to accelerate the rapid growth we have enjoyed over
the past few years.”
Mr. Douglas will continue in his
present position as President and CEO of Peerless with
reference to the Grundfos Group’s new Regional Managing
Director, Jes Munk Hansen.

Purified Wastewater from
Hospitals
 Duisburg,
Germany -- Hospital wastewater is contaminated with drugs
that can pollute the environment. A newly developed system
deals with the problem at source, directly treating and
purifying wastewater from the toilets before it ever reaches
the sewage plant.
Antibiotics, cytostatics and psychotropics - many are the
drugs swallowed by hospital patients. A certain amount of
these substances is excreted and finds its way into the
sewers. Traces of them can still be detected in the water
even after treatment in the sewage plant, as they are not
biologically degradable.
Experts are not yet fully able to predict the impact on the
environment. However, there are numerous indications that
the feminization of fish, the diminishing effect of
antibiotics, and even a reduced sperm count among young men
can be attributed to these residues in the water.
In a
joint project with the Duisburg Institute of Energy and
Environmental Technology IUTA, researchers at the Fraunhofer
Institute for Environmental, Safety and Energy Technology
UMSICHT have developed a means of treating hospital
wastewater right where it is produced – ensuring that toxic
substances never even reach the municipal water network.
The
outstanding feature of the system is that, rather than
tapping the hospital’s entire wastewater stream, it
concentrates on partial streams such as the toilet sewage
from the oncology department. This tends to be particularly
highly contaminated due to the medication administered to
patients in the course of chemotherapy, for example. Other
wastewater such as that of the hospital laundry or the
kitchen does not flow unnecessarily through the system – the
drugs are thus concentrated in small quantities by volume.
“The
method is extremely effective,” says Fraunhofer UMSICHT
project manager Bettina Becker. “Following treatment, over
99 percent of the tested substances have been dispelled and
can no longer be detected in an analysis.” The researchers
tested “wastewater” to which cyto-statics, antibiotics,
psychotropic drugs and pain-killers had been added. After
cleansing, it had completely lost the toxic and genetically
harmful effect.
This
is how the method works: First of all, the suspended solids
are deposited in a sedimentation tank. Then the water passes
into the reaction container, where ultraviolet light,
hydrogen peroxide or ozone produce radicals that destroy the
active drug ingredients. A prototype of the pilot plant,
which was planned and built with funds from the BMWi, is
currently installed at the IUTA.
Hospitals would be well advised to install such compact
plants in the wastewater system in future. There might even
be a financial incentive for doing so: Surcharges which
hospitals would otherwise have to pay for heavy
contamination of wastewater may no longer need to be levied.

Ohio WWTP's Implement
Reliability Program
 ATLANTA,
GA -- GE Energy and the Metropolitan Sewer District of
Greater Cincinnati (MSDGC) today announced the
successful implementation of a new reliability-based
asset management program for MSDGC’s wastewater
treatment network. The new system “went live” earlier
this month and is the culmination of a year-long project
that required GE to design and implement a comprehensive
program to improve MSDGC’s maintenance and operating
practices.
Improving the mechanical
reliability of pumps and other equipment, especially
during periods of peak demand such as after a rainstorm,
was a critical aspect of the project. The GE-designed
reliability program is part of a multi-faceted effort by
MSDGC to improve its environmental compliance through
better equipment reliability, ensuring that critical
pumps are able to run during peak demand times. The
program is also expected to reduce maintenance costs and
energy usage while simultaneously enhancing safety and
employee satisfaction.
Brian Palmer, vice-president
of GE Energy’s Optimization and Control business unit,
noted that, “the U.S. water and wastewater industry
faces a multitude of challenges due to aging
infrastructure and decreasing operating resources.
However, Cincinnati has risen to these challenges and is
establishing itself as a leader in proactive asset
management. We appreciate the confidence that the city
has placed in GE by allowing us to help design and
implement their newly launched reliability program.”
Tony Parrott, executive
director of MSDGC, was equally enthusiastic. “With GE’s
partnership, we have improved reliability, enhanced our
systems, and ultimately, saved the rate payers money by
implementing proven private sector practices into the
public sector,” said Parrott. “GE’s approach has been
impressive in coupling the changes to our work processes
with the upgrades to our technology.”

The Inside Story on
Moisture-Cured Coatings
It’s common knowledge
that polyurethane coating technology is an excellent
choice for demanding exterior applications such as
bridges, stadiums and other large structures. But
when maintenance was required inside the Hammond
Water Filtration Plant in Hammond, Ind., a
moisture-cured polyurethane system proved to be the
only way to go to coat more than 35,000 square feet
of piping and valves...(more) |
