| Résumé : | This work focuses on optimal operation of brackish water reverse osmosis (BWRO) plants employing multitrains which have different service times and membrane permeability parameters. A nonlinear optimization problem, based on a previously developed comprehensive RO model that accounts for characteristic curves of booster pumps driving the RO trains and pressure drop along each RO train, is formulated and solved to minimize the overall specific energy consumption (SEC) while maintaining the same overall water production. A 16–17% reduction in SEC is possible by optimizing production allocations among all trains as well as operating conditions within the normal pump operating range in each train. It is shown that optimizing each train individually (without optimizing production allocations) could yield a higher SEC. |
