  • Understanding Ultrapure Water and the

    As the feed water enters the RO membrane under pressure (enough to overcome osmotic pressure), the water molecules pass through a semi-permeable membrane and the salts and other contaminants are not allowed to pass and are discharged through the concentrate stream, which goes to drain or can be fed back (totally or partially) into the feed water stream to be recycled through the RO system to save water or to solve hydraulic issues in the system.
