Abstract
An apparatus, for use with a reverse osmosis system comprising a feed input, a concentrate output, and a permeate output, includes (i) at least one pressure sensor operative to measure a pressure of at least the permeate output of the reverse osmosis system and to generate a signal indicative of the pressure of at least the permeate output of the reverse osmosis system and (ii) at least one controller operative to adjust a speed of at least a first pumping mechanism based at least in part on the signal indicative of the pressure of at least the permeate output of the reverse osmosis system. The first pumping mechanism comprises at least one of: (i) a fluid input coupled to at least the permeate output of the reverse osmosis system; and (ii) a fluid output coupled to at least the feed input of the reverse osmosis system.
