Three envelopes — do not conflate them

32 and 40 MLD are theoretical membrane-system capacities derived from Pall's later 8-MLD/rack design basis, not demonstrated plant capacity. April 2026 data shows racks operating materially below that flux. Confirm common-system ratings (feed pumps, feed strainers, RF pumps/tank, compressed air, CIP, clearwell hydraulics, discharge piping) before using 32/40 MLD in any capacity, hydraulic guarantee, or expansion study.

Envelope 1

Physical

Racks: 4
Modules: 400
Membrane area: ~20,000 m²

Envelope 2

Pall design (theoretical)

Per rack: 8 MLD
Flux: 78–81 LMH
Recovery: 95.8–96 %
4 racks / 5-rack expansion: 32 / 40 MLD

Depends on feed-water quality, feed pumps, feed strainers, compressed-air capacity, RF/backwash equipment, piping hydraulics, and other ancillary equipment; Pall did not supply or re-rate several of these systems in the 2017 expansion review

Envelope 3

Observed operating (Apr 2026)

Per rack: 4.3 MLD typical, 5.9 MLD high
Flux: 36 LMH typical (30–45)
TMP: ~100 kPa
Share of Pall design flux: 45-55%

Observed operation is within the general O&M pressure range, but 50 psi is a broad module limit, not an operational TMP target. Alarm/shutdown setpoints should come from the plant PLC/SFD/O&M settings.

~38C CIP condition is near the upper end of the 0-40C membrane range; cleaning is governed by its own recipe/chemistry limits
