TI  - Power Generation Performance of a Pilot-Scale Reverse Electrodialysis Using 
      Monovalent Selective Ion-Exchange Membranes.

AB  - Reverse electrodialysis (RED) is a promising process for harvesting energy from 
      the salinity gradient between two solutions without environmental impacts. 
      Seawater (SW) and river water (RW) are considered the main RED feed solutions 
      because of their good availability. In Okinawa Island (Japan), SW desalination 
      via the reverse osmosis (RO) can be integrated with the RED process due to the 
      production of a large amount of RO brine (concentrated SW, containing ~1 
      mol/dm(3) of NaCl), which is usually discharged directly into the sea. In this 
      study, a pilot-scale RED stack, with 299 cell pairs and 179.4 m(2) of effective 
      membrane area, was installed in the SW desalination plant. For the first time, 
      asymmetric monovalent selective membranes with monovalent selective layer just at 
      the side of the membranes were used as the ion exchange membranes (IEMs) inside 
      the RED stack. Natural and model RO brines, as well as SW, were used as the 
      high-concentrate feed solutions. RW, which was in fact surface water in this 
      study and close to the desalination plant, was utilized as the low-concentrate 
      feed solution. The power generation performance investigated by the 
      current-voltage (I-V) test showed the maximum gross power density of 0.96 and 
      1.46 W/m(2) respectively, when the natural and model RO brine/RW were used. These 
      are a 50-60% improvement of the maximum gross power of 0.62 and 0.97 W/m(2) 
      generated from the natural and model SW, respectively. The approximate 50% more 
      power generated from the model feed solutions can be assigned to the suppression 
      of concentration polarization of the RED stack due to the absence of multivalent 
      ions.
