    Desalination Systems

    Turn seawater into drinking water

    Desalination systems use high-pressure reverse osmosis to make seawater and brackish water drinkable. From hand-pumped survival units to containerized systems for coastal homes and yachts, this is essential tech where freshwater is scarce.

    How to Choose: Desalination Buyer's Guide

    Match GPD to your need

    Survival units make a few liters an hour; home and marine systems are rated in gallons per day (GPD). Estimate daily demand before sizing.

    Energy and brine

    Seawater RO is energy-intensive (high-pressure pumps) and produces concentrated brine. Plan power supply and responsible brine discharge.

    Maintenance in salt environments

    Membranes and pumps need flushing with fresh water after use. Look for systems with easy membrane access and corrosion-resistant components.
