Sea Water Desalination by Reverse Osmosis (RO)

Singapore began tackling their drinking water supply problem a few years ago. The first large sea water desalination system “TUAS Desalination“ was designed and built by Hyflux Ltd. The system operates according to the reverse osmosis principle and produces more than 136,000 m³ of drinking water per day. This amount is enough to fill about 55 Olympic size swimming pools.
