  • Seawater Desalination With Reverse Osmosis | WWD

    2011-8-13 · In osmosis, the solvent water passes through the membrane until the pressure difference across the membrane is equal to the osmotic pressure (approximately 350 psig for a fresh water/seawater interface). In the reverse osmosis desalination process, a pressure greater than the osmotic pressure applied to the saline water will cause fresh water to flow through the membrane while holding back the …

  • Marine Reverse Osmosis System | Water Treatment

    Marine desalination systems are highly effective treatment methods for the production of fresh drinking water through the utilization of reverse osmosis. The reverse osmosis process works by utilizing high-pressure pumps to force seawater through a semipermeable RO membrane that consists of small pores, which prevents the salt and minerals from passing along through the system with the product water. …
