ENERGY RECOVERY, INC. : Oman Desalination Plant Uses Energy Recovery's PX Q300
                  for World's Largest Reverse Osmosis Trains

Designed to be the largest single reverse osmosis trains in operation
world-wide, Oman is highlighting Energy Recovery's scalability and technical
adaptability in desalination

SAN LEANDRO, Calif., September 13, 2013 - Energy Recovery, Inc. (NASDAQ:
ERII), the leader in capturing reusable energy from industrial fluid flows and
pressures cycles, announced today that one of the largest reverse osmosis
(RO) single train in the world will use its PX Q300 Pressure Exchanger®
technology to desalinate seawater in Al Ghubrah, Oman. The technological
first-a desalination mega-project producing more than 191,000 m³/day (50
million gallons per day) of potable and irrigation water in the Middle East
North Africa region (MENA)- will feature eight trains, each desalinating
30,000 cubic meters of seawater per day. This configuration will produce
potable water for approximately 800,000 residents, easing the intense
freshwater needs in the region. The Muscat City Desalination Company (MCDC)
formed by Cadagua, Malakoff, and Sumitomo will build, own and operate Al
Ghubrah Independent Water.

Energy Recovery's success in Oman and around the world led the plant-design
team to select the PX Q300. The EPC contractor, International Water Treatment
LLC (formed by Cadagua, Wabag and Galfar) has chosen PX technology to
ensure efficient, reliable energy recovery to overcome the challenges of
seawater processing in Oman. For an animated video showing how the PX device

Cadagua's Contract Director on the Al Ghubrah Plant shares why International
Water Treatment LLC trusts Energy Recovery to deliver the highest possible
efficiency: "Energy Recovery is well-known in the industry and the MENA
region. The highly reliable PX-Q300 was the most advantageous choice for us
on an RO train this size," states Emilio López Pacetti from Cadagua.

In the dry MENA region, seawater desalination is essential to continued
prosperity and vitality. The demand for agricultural, drinking, and industrial
water continues to increase along with economic development and population
growth. Because the region has more than six percent of the world's population
but access to just over one percent of the planet's renewable fresh water
resources, countries like Oman must find sustainable, affordable, and
efficient ways to offer potable water to its residents. Seawater processing
plants like the Al Ghubrah installation and technologies like Energy
Recovery's highly efficient and reliable solutions are helping to bridge that

Lower processing costs are crucial to the vitality of an area such as MENA
where water resources are significantly stressed. The Al Ghubrah plant will
see large benefits across its operational expense and impact; CO2 savings and
cost savings annually. "We designed the PX to be modular and adaptable. With
a bigger PX train, the efficiency values are higher and this reduces the net
reverse osmosis process," states Tom Rooney, CEO of Energy Recovery.

Energy Recovery PX Technology Highlights and Impact

Over the past decade, Energy Recovery has been refining its SWRO clean
technologies and employing its premium energy recovery solutions around the
world - currently accounting for 90 percent of the ERD market share globally.
The EPC consortium selected the PX Q300 device for the Al Ghubrah project
because the solution boasts:

· The lowest life cycle cost of any energy recovery device in the

  oHighest guaranteed efficiency of 97.2 percent.
  oHighest availability (99.8 percent uptime) with zero downtime.
  oSmallest installed footprint than any other ERD.
  oLifetime designed for 25+ years.
