Abstract: Highlights•Optimal net present value reverse electrodialysis (RED) process design and operation.•Recycle and reuse alternatives improves the cost-competitiveness of RED.•The optimal solution outperforms the conventional series staging of RED units.•Limited low-salinity feed restricts the electricity profits making RED unprofitable.•Efficient and systematic decision-making tool over simulation-based approaches.
