Energy Recovery

Energy Recovery, Inc. (Nasdaq: ERII), headquartered in San Leandro, California, designs and manufactures energy recovery devices that reduce energy consumption in desalination and industrial water treatment. Their core technology is the PX Pressure Exchanger, a ceramic-rotor device with a single moving part that captures and transfers pressure energy from brine reject to feed water, achieving up to 99% hydraulic efficiency and reducing energy use by up to 60% in SWRO facilities. The PX Q Series includes the PX Q650 (peak flow 650 gpm, a 63% capacity increase over its predecessor), PX Q400, PX Q300, PX Q260, PX Q220, PX Q180, and PX Q140, along with Low-Pressure, High-Pressure, and Ultra High-Pressure PX variants for different operating conditions. The PX PowerTrain integrates PX devices with frame support and ancillary equipment for pre-engineered RO train solutions starting at 3,000 CMD. Energy Recovery also manufactures turbochargers and high-pressure pumps. Over 35,000 PX devices are deployed worldwide, treating 43.6 million m³/day and saving customers $7.2 billion annually in energy costs while avoiding 22.5 million metric tons of carbon emissions. The company holds ISO certification and serves seawater desalination, brackish water RO, industrial wastewater, and MLD/ZLD applications. Recent contracts span Saudi Arabia ($32.8M), the Gulf region ($31M), and Spain ($7M+).
