- •
Batch-like processes yield similar energy savings as staging with energy recovery.
- •
Semi-batch RO and two-stage RO show similar promise for seawater RO.
- •
A practical batch RO process shows promise for high recovery brackish water RO.
- •
Process inefficiencies hinder batch-like processes more than staged processes.
- •
Capital cost and process robustness should be considered in addition to energy use.
