Energy Recovery Awarded $3 Million for Desalination Retrofit Projects in Europe

SAN LEANDRO, Calif.—April 24, 2017 — Energy Recovery, Inc. (NASDAQ:ERII), the leader in pressure energy technology for industrial fluid flows, today announced total awards of roughly $3 million to supply its PX^TM Pressure Exchanger^TM technology to retrofit several desalination plants in Europe. The orders are expected to ship in the in the second half of 2017.

Energy Recovery will supply its PX-Q300 and PX-Q260 Pressure Exchanger devices for the plants, replacing existing turbine technology. The projects will collectively produce a total of up to 133,000 cubic meters of water per day. Energy Recovery estimates the PX devices will reduce power consumption for all projects by 2.5 MW, saving over 21.4 GWh of energy per year, and helping the plants avoid more than 12,000 tons of CO₂ emissions per year.

Energy Recovery’s President and CEO Joel Gay stated, “These awards are yet another proof point around our technological leadership within the global desalination market. We will continue to aggressively attack the brownfield retrofit market, targeting plants with legacy solutions thereby continuing to grow our share of the desalination wallet and execute against our long term strategy. The PX Prime^TM and Prime Performance Energy Services Agreement, or ESA, will be yet another tool in our repertoire which we will utilize to unseat the competition and provide the premier energy recovery solutions to our ever-growing customer base.”
