Abstract
A reverse osmosis system and method includes a feed pump pressurizing a feed stream, a first and second membrane array that generates permeate and brine streams. A first turbocharger uses first energy from the second brine stream to pressurize the first brine stream. A first and second auxiliary and bypass valves are associated with the first and second turbocharger. A second turbocharger uses second energy from the second brine stream to increase a second pressure of the feed stream. A first flow meter generates a first flow signal for the first permeate stream. A second flow meter generates a second flow signal for of the second permeate stream. A third flow meter generates a third flow signal for the second brine stream or the feed stream. A motor drives the first turbocharger or the feed pump. A controller controls the motor in response to the flow signals.
