Desalination: Seawater and Brackish Water Treatment
Membrane systems, antiscalant dosing, pre-filtration, valves, media filters, and storage across five vendors named specifically for seawater and brackish water desalination.
What the Evidence Actually Supports
Five independent vendors in the LibertyCES catalog name desalination or the closely related BWRO/SWRO application directly. Of the six equipment categories that evidence supports, two are strongly evidenced — AXEON's X3-Series BWRO/SWRO membrane systems and Epiphene's CPH-16 chemical-free silt separation, which explicitly names "RO & Desalination" in its own application list. The other four — antiscalant dosing, the high-performance butterfly valve, the media filter, and the storage tank — are named by their vendors as serving desalination without a desalination-dedicated spec sheet behind that naming. This page is scoped and depth-matched to that real evidence rather than written as a comprehensive desalination engineering guide.
Six Categories, Five Vendors
"Strong" evidence means desalination or RO/BWRO/SWRO is explicitly named as an application in the vendor's own published material. "Moderate" means the vendor names desalination as a served sector without a desalination-specific spec document behind it.

Frequently Asked Questions
Is this page a comprehensive desalination engineering guide?
No — this is a reference table sized to real, verified vendor evidence, not a comprehensive full-system guide. Of the six equipment categories captured, only two (AXEON's X3-Series membrane systems and Epiphene's CPH-16 silt separation) carry strong sector-specific evidence. The remaining four — antiscalant dosing, the butterfly valve, the media filter, and the storage tank — carry moderate evidence: the vendor explicitly names desalination as a served sector, without a desalination-dedicated spec sheet.
Does Epiphene's chemical-free silt separation actually name RO and desalination as an application?
Yes — checked directly against Epiphene's own homepage application list, which names "RO & Desalination" explicitly: precision pre-filtration to protect membranes and reduce chemical cleaning cycles. This is real, confirmed evidence, not an inferred link — the CPH-16's physical nucleation-seed removal approach is complementary to, not a replacement for, AXEON's chemical antiscalant dosing on the same membrane train.
What is the difference between AXEON's antiscalant dosing and Epiphene's silt separation on the same RO train?
They address the same scale-fouling problem through different mechanisms. AXEON's PWS-Series injects antiscalant chemistry ahead of the membrane to chemically inhibit crystal growth. Epiphene's CPH-16 physically removes the microscopic silt/sand particles that would otherwise seed scale formation before it starts. A desalination specification can reasonably call for either or both, depending on whether the priority is minimizing chemical dosing infrastructure or adding a physical pre-filtration stage.
How does this desalination page differ from the industrial process water filtration page?
The industrial process water filtration page covers general industrial cartridge, RO pre-treatment, and cooling-loop filtration across production lines broadly. This page is scoped specifically to seawater and brackish water desalination — the membrane systems, antiscalant dosing, silt pre-filtration, valve, media filter, and storage equipment named specifically for that application by their vendors.
