The energetics of the original Closed-Circuit RO (CCRO) may be improved by adding a reciprocating-piston cylinder whose size may not be adjusted in real time during operation, thus limiting the maximum stroke length of the piston. In this work, the effect of the actual-to-ideal ratio of cylinder sizing on the performance of the improved CCRO is analyzed. If the cylinder is under-sized, the CC filtration step may start with the original CCRO and transition to the improved CCRO. If over-sized, only the improved CCRO is implemented, while the CC filtration and flushing periods are extended. For ultra-high recovery applications studied in this work, under-sizing the cylinder by 70 % or over-sizing by 50 % revealed a 2 % or less extra energy consumption using a spatiotemporal model, confirming its operational flexibility.
