Real Specifications
| Spec | Value | Source document |
|---|---|---|
| BWRO feed water TDS range | 1,000-10,000 ppm, high-pressure pumps rated 350-500 psi | AXEON Water Technologies — Reverse Osmosis / Membrane Systems |
| SWRO salt rejection | Up to 99.8% salt rejection; X3-Series uses a duplex stainless steel axial piston pump | AXEON Water Technologies — Reverse Osmosis / Membrane Systems |
| Antiscalant dosing confirmation | Membrane life extended via advanced cleaning techniques and antiscalant chemical dosing; BWRO recovery rate up to 75% | AXEON Water Technologies — Reverse Osmosis / Membrane Systems |
| Epiphene CPH-16 capture efficiency | 66% removal at 5 microns, 94% removal at 15 microns, 30% removal at 1 micron in a single pass (at specific gravity 2.6) | Epiphene Incorporated — Chemical-Free Sub-Micron Silt Separation & Scale Prevention |
| Epiphene mechanism | Physically removes 0.1-10 micron nucleation-seed particles that scale (e.g. calcium carbonate) needs to crystallize on, as a chemical-free alternative/complement to antiscalant dosing | Epiphene Incorporated — Chemical-Free Sub-Micron Silt Separation & Scale Prevention |
Both AXEON's chemical antiscalant dosing and Epiphene's physical seed-particle removal exist to prevent the same failure mode — dissolved minerals nucleating and scaling the membrane surface — approached from opposite directions, chemical vs. physical.
Antiscalant dosing and physical nucleation-seed removal are two different answers to the same failure mode: scale forming on the membrane surface. Which one is correct depends on whether the customer wants to add a chemical dosing loop or eliminate it — AXEON's dosing supports up to 75% recovery on brackish water, while Epiphene removes the 0.1-10 micron seed particles before they ever reach the membrane.
