The RO produced water quality is depending on Feedwater quality, Membrane quality, reject ratio and operating pressure. At higher salty feedwater, higher operating pressure, lower rejection and lower membrane separation quality, there will be higher TDS (including hardness, alkalinity, chlorides or whatever exists in feedwater) on produced water.
