Technical capabilities and regional support
Reverse osmosis membranes operate under intense hydraulic pressure to strip dissolved ions, silica, and organic molecules from water supplies. Desalytics supplies premium brackish water (BWRO), seawater (SWRO), and fouling-resistant (FR) spiral-wound elements engineered with advanced polyamide chemistry to deliver unmatched rejection rates and low feed-pressure energy requirements.
RO Element Specifications
- Brackish Water Elements (BWRO): High-permeability elements operating at low feed pressures, ideal for municipal groundwater, boiler feed, and commercial systems.
- Seawater Elements (SWRO): Heavy-duty fiberglass-wrapped elements designed for operating pressures up to 1,200 psi with 99.8% nominal NaCl salt rejection.
- Fouling-Resistant (FR) Feed Spacers: Specialized thick 34-mil feed spacer geometry designed to resist bio-slimes and particulate bridging in challenging waters.
The Desalytics Operational Advantage
- OEM Certified Direct: Brand-new, factory-sealed elements from leading global membrane fabricators backed by full manufacturer performance warranties.
- Direct Replacement Equivalents: Cross-referencing capabilities to find drop-in replacements for discontinued or high-lead-time elements.
- On-Site Autopsy & Loading Support: Assistance with vessel re-shimming, brine seal orientation, and proper chemical sanitization during initial plant wet-out.
