Business Wire
Energy Recovery, Inc. (NASDAQ: ERII), a leader in the design and
development of energy recovery devices for desalination, today
introduced its QuadribaricTM technology, advancing the company’s
mission to make seawater desalination an affordable solution to
addressing the world’s clean water shortages. Embedded into the
latest PX Pressure Exchanger™ (PX-300) line of rotary energy
recovery devices, ERI Quadribaric technology uses a patented new
design that revolutionizes the way PX devices work—essentially
doubling the work load of each device—with greater efficiency than
any energy recovery device on the market.
“Energy Recovery is continually developing technologies to
support the evolving needs of desalination plants and to help
deliver environmentally friendly, low-cost water to the world.
Quadribaric technology is our latest enhancement and establishes a
new performance standard for the industry,” said Dr. Richard
Stover, ERI’s chief technology officer. “With the PX-300 device,
Energy Recovery is supporting the growing capacity demands of
larger desalination plants, where lower operating pressures, higher
efficiencies and longer product life are essential to success.”
Energy Recovery introduces a number of distinct benefits to
desalination facilities around the world with the new technology,
including:
- Higher Efficiency:
Quadribaric technology features straighter flow paths than
previously possible, improving efficiency.
- Less Mixing: With its
reduced cycle speed, Quadribaric technology achieves minimal mixing
between the seawater concentrate and feed water, supporting lower
operating pressures in desalination systems.
- Greater Reliability: The
slower rotational rate of the Quadribaric technology design extends
product life cycle.
- Quieter Operation:
Quadribaric technology uses a smoother exchange process, reducing
the sound level produced by its operation.
“As the first ERI device to leverage the company's new
Quadribaric technology, the PX-300 unit combines excelled
isobaric technology design and state-of-the-art of vessel and port
configuration to yield increased production capacity and improved
energy recovery efficiency at a competitive price,” said Nikolay
Voutchkov, president of Water Globe Consulting, LLC. “I would
expect the PX-300 to become the new 'standard' for energy recovery
equipment in medium and large-size desalination plants, and look
forward to seeing the benefits these facilities gain with the new
ERI design.”
The Energy Recovery PX device is used in hundreds of
desalination plants around the world. More than 7,000 PX devices
are currently deployed or under contract to be installed at
desalination plants across the globe. All combined, these devices
deliver more than six billion liters of clean water each day—an
average of one liter for every person on the planet. By using ERI
PX devices to recycle wasted pressure energy, desalination plants
are able to reduce the energy consumption of SWRO systems by up to
60 percent, making desalination a cost-effective solution for clean
water supply. PX devices also reduce the carbon footprint of
desalination, saving more than 750 MW of energy and reducing CO2
emissions by more than 4.6 million tons per year worldwide. With
the new Quadribaric technology, each unit shipped will mean even
greater energy savings and environmental benefits, helping meet the
growing demand for clean, affordable water supply demands.
