More Info on Energy Recovery, Inc.

Energy Recovery creates technologies that solve complex challenges for industrial fluid-flow markets worldwide. Building on our pressure exchanger technology platform, we design and manufacture solutions that make industrial processes more efficient and sustainable. What began as a game-changing invention for desalination has grown into a global business accelerating the environmental sustainability of customers’ operations in multiple industries. Headquartered in the San Francisco Bay Area, we are a global team with sales and on-site technical support available worldwide.

Generating Cost Savings and Increasing Efficiency

We are committed to developing technologies that reduce operating costs for our customers. Our solutions drive long-term value and improve the productivity of our customers’ operations by reducing energy consumption and lifecycle cost, including repairs, maintenance, and equipment downtime.

Our company started in water desalination, where our flagship PX® Pressure Exchanger® (PX) energy recovery device today saves water desalination customers approximately USD $3.9B in energy costs annually. The reliability and lifetime value proposition of our PX make it seawater reverse osmosis (SWRO) desalination’s most trusted and industry standard energy recovery device.

Accelerating Technical Innovation

Our core technology is the pressure exchanger. This versatile technology is at the heart of many of our products and can handle different industrial fluids and pressures. The first application of our pressure exchanger technology, the PX, revolutionized SWRO desalination by addressing a key pain point: energy intensity. The PX reduces energy use by up to 60% in SWRO facilities – significant savings that allowed SWRO to supplant thermal desalination as today’s desalination technology of choice. Today we continue to push the boundaries of our core technology to handle different operating environments and industrial applications.

Delivering Environmental and Social Impact

Our customers do not have to sacrifice quality for sustainability. Our technology makes industrial fluid-flow processes more efficient and environmentally sustainable, saving energy, reducing waste and minimizing emissions. We are proud of our role in accelerating the environmental sustainability of our customers’ operations and, where applicable, supporting customers to meet environmental regulations and requirements.  Our PX, which generates no emissions when operating, allowed our desalination customers to avoid 30 terawatt hours and approximately 14.5 million metric tons of carbon emissions in 2021 – equivalent to removing more than 3 million passenger vehicles from the road annually*. Thanks in part to our PX, SWRO is a cost-effective, energy-efficient option to deliver clean water to people in water-scarce locations.
