  • Energy saving method using 2-stage reverse osmosis

    Reverse osmosis (RO) is the leading method of desalination. RO provides secure water resources amidst the increasing demand for water, reduction of water resources, and increasing pollution of water. Many current water desalination systems use a single-stage RO system, which operates at high pressure through the whole system, and therefore ...

  • Reverse osmosis stage vs pass - Water Treatment and ...

    A 'pass' shall be seen as a stand alone RO system . The difference between a single pass RO system and a double pass RO system is that with a double pass RO, the permeate from the first pass becomes the feed water to the second pass (or second RO) which ends up producing a much higher quality permeate because it has essentially gone through two RO systems.
