CCD & CC-PRO proceed with near absolute energy conversion efficiency without ERD.
High recovery low energy CCD meets all future targets of the desalination industry.
Detrimental effects on flux in PRO manifested by actual/ideal FO flux ratio
Desalination by FO–RO and/or PRO–RO hybrids is energetically inferior to direct CCD.
High recovery low energy water rescue from TSE by CCD is of highest cost effectiveness.
