RO System Recovery

The fraction of the RO feed flow that is recovered as permeate. Recovery is the primary control on concentrate flow, applied membrane concentration, and scaling risk, and is bounded by feed chemistry and membrane configuration.

RO Membranes

Semi-permeable membrane elements used in reverse osmosis systems to reject dissolved salts and other constituents under applied feed pressure. Performance is described by the manufacturer (flow, rejection, pressure limits) rather than by third-party ratings.
