Abstract: A simple approach has been implemented to identify the optimum RO (Reverse Osmosis) system structure and the operating parameters leading to the minimum total cost. Various two-stage and three-stage arrangements of practical functionality have been optimized. All possible operating points and its corresponding cost have been obtained and a linear search is used to find the minimum cost. The minimum overall costs per unit permeate for the single, two and three-stage arrangements are 1.41, 1.00 and 0.91 $/m3 respectively at product rates of 5.5, 11.5 and 17 m3/h.
