- 900 GPD High-Output Seawater Desalination: Produces up to 900 gallons of fresh drinking water per day (at 800 psi working pressure), converting seawater into clean, potable water for boats, yachts, and coastal applications.
- Complete Multi-Stage Filtration + Built-in UV: Seawater passes through stainless-steel mesh filter → 20-micron PP → 5-micron PP → high-pressure RO membrane → built-in LED UV in the control box, removing up to 99% of dissolved salts, bacteria, heavy metals, and impurities.
- Marine-Ready Design with Suction & Booster Pumps: Dedicated suction pump maintains stable flow even when the vessel is in motion; high-pressure booster pump delivers the 600–900 psi required for efficient seawater reverse osmosis
- Automatic Membrane Flushing System: Equipped with an automatic flusher that periodically rinses the RO membrane with filtered water to prevent salt buildup, biofilm, and scaling. Manual or weekly automatic flush options available.
- Smart Control Box for Convenient Operation: Features TDS display, dual pressure gauges, flow meter, pressure regulators, and easy pump controls — designed for marine electrical systems (110V / 20A).
- Easy Maintenance & Long Filter Life: PP&CTO filters last up to 6 months; RO membrane up to 3 years (depending on water quality). Clear installation diagrams, quick-connect fittings, and lifetime U.S.-based technical support.

Features
The iSpring BRO900 is a professional onboard seawater desalination system built for boats, yachts, and coastal living. It turns seawater into reliable fresh drinking water at up to 900 GPD (under 800 psi working pressure), giving you true independence from shore-based supplies.
Engineered specifically for marine conditions, the system combines a stable suction pump, high-pressure booster pump, multi-stage filtration, and a built-in UV module to deliver clean, safe water even while underway. An automatic membrane flush protects the RO membrane from salt buildup and scaling, while the smart control box provides clear real-time monitoring of TDS, pressure, and flow.
With long filter life, quick-connect fittings, and lifetime technical support from iSpring’s U.S. team in Atlanta, the BRO900 is designed for real-world marine reliability — whether you’re cruising coastal waters or living aboard.
