New
Drive Increases Efficiency & Reliability
SEATTLE--(BUSINESS WIRE)--Oct. 29,
2002--When it comes to material handling and pumping, producers who
move product efficiently make the most money.
Conversely,
poorly engineered systems or less-than-optimal components result in
downtime, wasted resources, safety issues and reduced profit.
MagnaDrive Corporation, in Seattle, Wash., has a solution that is
delivering major efficiency, reliability and safety improvements to
operators nationwide, the company announced today.
MagnaDrive's power transmission
technology utilizes powerful rare-earth permanent magnets to
transmit torque across an air gap with no physical connection
between the motor and driven equipment. MagnaDrive's Adjustable
Speed Drive is for variable speed applications up to 1500 HP, such
as pumps, fans and blowers, where precise process control, energy
savings, reduced vibration and low maintenance are desired.
The MagnaDrive Coupling is designed
for constant speed applications up to 1000 HP, such as conveyors and
pumps, where low cost, easy installation, efficient torque transfer
without vibration, overload torque protection, cushioned start and
stop, misalignment tolerance and low maintenance are desired.
A unique benefit of the MagnaDrive
Coupling is its performance in torque overload situations such as
material jams or excess weight. The Coupling automatically
disengages, shutting down the system and preventing damage or
destruction of the motor and driven equipment.
MagnaDrive President and CEO, Ron
Woodard, sees huge potential for MagnaDrive equipment in mining,
power generation and other material handling systems.
"Customers tell us that MagnaDrive products are easy to install
and align, significantly increase reliability, and greatly reduce
downtime and maintenance costs," said Woodard.
"...achieving accuracy
in sampling and ...of taking reproducible samples from a
population of non-ordered objects, ensuring the
reproducibility of samples taken from a series of
chronologically ordered objects, and other applications of
sampling theory."

Reduce
Arsenic
to less than 10ppb
USFilter Obtains NSF Cert for GFH
Arsenic Removal Media
PALM DESERT, Calif., Nov. 5, 2002 —
USFilter has obtained NSF Standard 61 certification for its GFH (Granular
Ferric Hydroxide) arsenic removal media. The media removes arsenic
from potable water supplies and helps existing plants meet the new
arsenic standards that by 2006 will lower the maximum amount of
arsenic allowed in drinking water from 50 parts per billion (ppb) to
10 ppb.
"This
certification assures our customers that the media used to purify
their drinking water is safe in itself,” states Dr. Paul
Gallagher, development director for USFilter.
ANSI/NSF Standard 61 certification
addresses crucial aspects of drinking water system components,
namely whether contaminants that leach or migrate from the
product/material into the drinking water are above acceptable levels
in finished waters. The standard addresses possible health effects
of treatment chemicals and related impurities, which are considered
contaminants for evaluation purposes.
The GFH media is a single-use,
adsorption media for removal of arsenic, antimony, selenium and
other heavy metals. GFH systems are ideal for wellhead applications
where no current arsenic removal treatment is in place. The media is
installed in pressure vessels where water simply passes through the
media for removal of the contaminants. Existing systems need only
install the treatment vessels between the well pump and distribution
system.
Operation of the system is easy and
relatively inexpensive as no pretreatment chemicals are needed and
backwashing occurs on a monthly basis. GFH media is removed from the
vessel and replaced with new media once the adsorption capacity is
consumed. Spent media has been shown to pass toxicity characteristic
leaching procedure (TCLP) testing so solid waste disposal can be
made at a sanitary landfill.
“USFilter is pleased to add GFH
media to our broad range of arsenic removal solutions,” adds
Stratton Tragellis, vice president of sales and marketing at
USFilter.

Works
in Existing Lagoons
New State-of-the-Art Wastewater
Aeration System
TAFT, CA - Biomixer
Corporation, which designs and fabricates an award-winning line of
aeration and mixing systems for wastewater treatment, has completed
the installation of two Biomixer systems (model 400-85-10 and model
400-60-10) for the city of Taft, California. The city upgraded their
wastewater facilities to remain in compliance with state and federal
environmental regulations, but had the challenge of procuring a
system that worked efficiently in their existing lagoons.
“Because
the wastewater facilities at Taft are lagoons, a conventional
bolted-to-the-floor-type fine bubble treatment system was not an
option,” said Win Freeman, President, Biomixer Corporation. “Biomixer
worked perfectly for Taft because the systems install from the
surface, requiring no additional infrastructure or draining and
provide significant energy savings.”
Randy Johnson, of Eco Resources, the
company that operates the wastewater treatment system for the city
of Taft, selected Biomixer for two key reasons: “Biomixer offers
unique fine-bubble efficiency and energy efficiency,” explained
Johnson. “The Biomixer fine-bubble system adds oxygen to the
process to enable the discharge of acceptable quality effluent,
while cutting our energy bill in half; it was a win-win solution for
the community of Taft and we are very pleased with the performance
of the Biomixer units and the professional service that we received
from the company.”
Last month, the Water Environment
Federation (WEF) presented Biomixer with its highest award for 2002:
the prestigious Innovative Technology Award in the Process Equipment
category. The privately-held Hawthorne, CA company has made
significant investment in recent years in their award-winning
technology, which combines fine bubble efficiency and tremendous
mixing capabilities with a patented variable-depth operating system
for efficient and energy-saving automatic dissolved oxygen control.
According to Freeman, “the company has a long-term commitment to
improving water standards in the U.S. and around the world, and
safeguarding for the next generation our most precious resource --
water."
The Biomixer System is unique in that
it requires no additional infrastructure. It comes pre- assembled
and installs from the surface in less than 24 hours. As such, there
is no draining required for installation or maintenance, and
therefore no disruption in service. Biomixers also are designed to
create a healthier and safer environment for personnel and
municipalities. Other types of aeration systems can create surface
aerosoling, which releases odors and dangerous pathogens into the
air. Because the Biomixer System aerates wastewater from beneath the
surface, versus spraying the wastewater into the air, the
possibility of toxins being carried by wind into the air is
eliminated. This is a major benefit to the personal health of plant
employees and neighboring communities.

Mr. Viance needs help with
biological treatment:
MDF production has waste water
effluents only in winter time and these effluents have high organic
contents as it comes from wood washing. Is biological treatment
feasible for this kind of effluents?

I am working with a sewage collection
system that is trying to reduce their pumping problems due to
erratic readings at their sewage lift stations.
They currently use the leading brand
of ultrasonic level transmitters connected to plcs to control the
lift station pumping. The sensor placements have been done in
accordance with the recommendation of the manufacturer, and we still
occasionally have problems that result in the high and low level
floats being actuated.
The manufacturer has suggested
installing stilling wells in the wet-wells to eliminate foaming and
surface agitation. The added maintenance costs associated with
stilling wells in wet-wells does not make this an attractive
alternative.
I am looking for possible
alternatives to the ultrasonic level measurements that have been
proven in sewage lift station operation.
