What makes large-scale seawater RO viable is the pre-treatment stack upstream of the membranes - SDI control, antiscalant dosing, and temperature-adjusted pump sizing are what separate reliable plants from chronic fouling problems. For brackish or lower-TDS sources, smaller industrial RO systems follow the same pre-treatment logic at a fraction of the scale.
