Validation Notes
Stable Rejection & Boron Removal
Aquaporin protein channels deliver exceptional salt passage consistency, ideal for single-pass SWRO. Typical boron rejection >92% under seawater conditions.
Marine-Grade Design
Robust 28 mil feed spacer reduces fouling and improves cleanability in harsh marine and high-salinity environments.
WHO-Aligned Permeate Quality
High boron rejection supports drinking water guidelines when used in properly designed seawater desalination trains.
Standard 8040 Format
Fits any standard 8-inch inner diameter pressure vessel — same installation envelope as conventional seawater RO elements.
