Seawater Desalination Case Studies – Selecting the Right Pretreatment

Seawater desalination plant design strategies are examined through six global case studies addressing climate change impacts on source water quality. Key design factors evaluated include seawater salinity, specific ion concentrations, turbidity, total organic carbon, and seasonal marine growth variability. Treated water quality objectives, reliability requirements, and regulatory constraints are integrated into RO system configuration decisions including recovery rates, multiple-pass arrangements, and pretreatment selection to ensure long-term operational resilience.
