Abstract:
A reverse osmosis system and method includes a pump pressurizing a feed stream, a first and second membrane array that generates permeate and brine streams. A first energy recovery device 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 energy recovery device. A second energy recovery device uses second energy from the second brine stream to increase a second pressure of the feed stream. A first flowmeter generates a first flow signal for the first permeate stream. A second flowmeter generates a second flow signal for of the second permeate stream. A third flowmeter generates a third flow signal for the second brine stream. A motor drives the first energy recovery device. A controller controls the in response to the flow signals.

Claim (Index 1):
A reverse osmosis system comprising:\n a pump operable to pressurize a feed stream; a first membrane array configured to receive the feed stream and to generate a first permeate stream and a first brine stream from the feed stream; a second membrane array configured to receive the first brine stream and to generate a second permeate stream and a second brine stream from the first brine stream; a first energy recovery device configured to receive the second brine stream and to use first energy from the second brine stream to increase a first pressure of the first brine stream; a first auxiliary valve and a first bypass valve associated with the first energy recovery device; a second energy recovery device configured to receive the second brine stream after the first energy recovery device and to use second energy from the second brine stream to increase a second pressure of the feed stream; a second auxiliary valve and a second bypass valve associated with the second energy recovery device; a first flowmeter generating a first flow signal corresponding to a first flow of the first permeate stream; a second flowmeter generating a second flow signal corresponding to a second flow of the second permeate stream; a third flowmeter generating a third flow signal corresponding to a third flow of the second brine stream; a motor coupled to the first energy recovery device, operable to use energy from a power supply to drive the first energy recovery device; and a controller in communication with the first flowmeter, the second flowmeter, and the third flowmeter, said controller controlling the first auxiliary valve, the first bypass valve, the second auxiliary valve and the second bypass in response to the first flow signal, the second flow signal and the third flow signal.
