Sources and updates
Scope of this page: Exact BW model and explicitly labelled BWRO portfolio operating limits. Flow is omitted because cards and table contain inconsistent figures for some models, and GPD/m³ conversions are not uniform. BW-2521 is excluded here because its8% table recovery differs from generic15% test text. No conflicting figure is resolved by inference or another supplier; no plant recovery, lifetime, direct replacement or energy-saving guarantee is adopted.
