Isobaric energy recovery in desalination plants

| By Gerald Ondrey

The new FLEX isobaric energy recovery device (photo) is this company’s next-generation compact pressure exchanger for reverse osmosis (RO) plants. The FLEX pressure exchanger is designed to be one of the most efficient and compact energy-recovery devices on the market. With its ability to recover more than 98% of hydraulic energy and offer the highest unit capacity available, while being notably smaller than competitor products, the FLEX pressure exchanger can substantially reduce the cost of desalination by lowering operating and capital expenditures, the company says. The FLEX offers a simple design with only four major internal components and is enabled for remote monitoring through the company’s RedRaven IOT platform. — Flowserve Corp., Dallas, Tex.
