RO Production Rate (ROP)
Rate at which the RO/DI bank makes purified base water. Falling output is the early tell of a fouled membrane; NEREID forecasts it against reservoir level to schedule service before a zone runs dry.
Threshold Bands
| Band | Range | State |
|---|---|---|
| Nominal | ≥ rated | OK |
| Fouling | 70–100% rated | WARN |
| Failing | < 70% rated | CRIT |
Formula
Permeate output of the reverse-osmosis bank feeding the mixing reservoirs.
