Real Specifications
| Spec | Value | Source document |
|---|---|---|
| PWS-Series chemical injection | PWS-Series includes a 'chemical injection system for membrane protection' as a standard listed feature | AXEON Water Technologies — Reverse Osmosis / Membrane Systems |
| Brackish RO feed TDS/pressure | BWRO feed water TDS range 1,000-10,000 ppm; high-pressure pumps rated 350-500 psi | AXEON Water Technologies — Reverse Osmosis / Membrane Systems |
| Seawater RO salt rejection | Up to 99.8% salt rejection on SWRO systems | AXEON Water Technologies — Reverse Osmosis / Membrane Systems |
| Cleaning trigger thresholds | CIP triggered at normalized permeate flow decrease of 10-15%, normalized salt passage increase of 10-15%, or pressure drop increase of 15-20% | AXEON Water Technologies — Reverse Osmosis / Membrane Systems |
AXEON's own foulant-to-cleaner reference table ties inorganic scaling directly to inadequate antiscalant dosing — the real failure mode a desalination metering pump exists to prevent is membrane scale buildup, tracked by the vendor's own trigger thresholds.
A reverse-osmosis membrane doesn't fail all at once — AXEON's own cleaning-trigger thresholds (flow decrease, salt passage increase, pressure drop) exist because scale buildup is gradual, and the antiscalant metering pump upstream is what keeps those numbers from drifting into replacement territory.
