Calder ERT energy recovery turbines are designed and manufactured specifically for reverse osmosis desalination. They can recover as much as 90% of the hydraulic energy remaining in the brine stream, converting it into rotary power for the high-pressure pumps. Highly efficient and reliable, Calder ERTs are installed in nearly 1000 seawater and brackish water reverse osmosis plants worldwide, with a total installed capacity in excess of 350 MW.

The Calder DWEER work exchanger is the most efficient energy recovery device (ERD) ever developed. It can recover up to 98% of the energy in the brine waste stream, which is then used to pressurize raw water and reduce the energy input for the high-pressure feed pumps up to 60%. With the DWEER, the high-pressure pump does not have to be connected to the energy recovery device. This permits the use of fewer, but larger, more efficient pumps.
