Claim Text:
1. A reverse osmosis system comprising: a reverse osmosis unit including a plurality of filter banks configured to pass permeate and generate concentrate; an instrumentation unit coupled to the reverse osmosis unit and having a plurality of sensors for sensing operational data of the reverse osmosis unit, the plurality of sensors including a flow sensor configured to detect a permeate flow rate of the permeate and a dissolved solid detection unit configured to detect an amount of dissolved solids in the concentrate; a processor coupled to the instrumentation unit and configured to calculate a normalized permeate flow rate based on the operational data including the permeate flow rate and the amount of dissolved solids in the concentrate and to determine whether to clean or replace the plurality of filter banks based on the normalized permeate flow rate; and a display coupled to the processor and configured to display data indicating whether to clean or replace at least one of the plurality of filter banks.
