High Rejection Reverse Osmosis Published on September 28, 2020 07:27 by WEI CHOEW LEE, Employee at Organo (Asia) Sdn Bhd in Case StudiesI come across a single pass RO system which can achieve the conductivity < 1 microS/cm (feed water is <80microS/cm) when it is pre-treated with softener. Can I know who has such RO design or product in the market?
