Bicarbonate conversion assisted reverse-osmosis (RO) treatment systems for treatment of contaminated water, particularly natural gas flowback water. The systems and processes provide for simultaneous conversion of the primary salt in gas production flowback waters from sodium bicarbonate to sodium sulfate, and flotation removal of organic contaminants, for the enhanced water recovery by RO of these waters. In the systems and processes, RO processes are enhanced by lowering the osmotic potential of the water being processed, by converting the bicarbonate ions to sulfate ions. |
