Seawater Desalination Pretreatment
Flocculant, antiscalant and defoamer dosing with online SDI monitoring to protect RO membranes.
Challenges
Tidal swings outpace dosing adjustments; SDI exceedances threaten high-pressure RO membranes.
Our Approach
Flocculant dosed by turbidity/flow dual parameters with SDI alarming; antiscalant and defoamer auto-dosed.
Key Points
Auto flocculant dosing
SDI early warning
Chemical optimization
