SWRO watermakers engineered for marine, coastal, and island applications. Energy-recovery technology delivers fresh water from the sea efficiently and reliably.
Get SWRO QuoteHigh-rejection seawater membranes produce potable water meeting WHO Guidelines for Drinking-water Quality from ocean water up to 45,000 ppm TDS.
Pressure exchanger ERDs recover up to 60% of energy, reducing specific energy consumption to 3–5 kWh/1,000 gal of permeate.
Super duplex stainless steel and FRP components withstand harsh marine and coastal environments without corrosion.
Off-grid capable with integrated solar power management and battery storage for remote coastal and island deployments.
| Model | Capacity (GPD) | Feed TDS | Power (kWh/kgal) | Application |
|---|---|---|---|---|
| SW-300 | 300 | 35,000 ppm | 12–15 | Yacht, sailboat |
| SW-1500 | 1,500 | 42,000 ppm | 8–10 | Small vessel, island home |
| SW-5000 | 5,000 | 42,000 ppm | 5–7 | Resort, coastal community |
| SW-20K | 20,000 | 45,000 ppm | 4–5 | Small municipality |
| SW-100K | 100,000 | 45,000 ppm | 3–4 | Municipal, industrial |
| SW-500K | 500,000+ | 45,000 ppm | 3–4 | Large municipal plant |
Compact watermakers with automatic flush and standby modes for vessels of all sizes on extended voyages.
Reliable freshwater from the sea for remote islands with limited groundwater. Solar-hybrid options eliminate fuel dependency.
High-volume desalination for hotels, resorts, and tourism developments along coastlines worldwide.
Large-scale SWRO for cities and towns facing freshwater scarcity, aquifer depletion, or drought conditions.
SWRO forces seawater through semi-permeable membranes at 800–1,000 psi, separating dissolved salts and contaminants from fresh water. AMPAC SWRO systems achieve 99.5%+ salt rejection and incorporate energy recovery devices (ERDs) to reduce power consumption.
Modern AMPAC SWRO systems with energy recovery devices consume 3–5 kWh per 1,000 gallons of permeate — significantly less than thermal desalination methods such as MSF or MED.
Yes. AMPAC offers solar-hybrid SWRO systems for off-grid coastal and island installations. Integrated battery storage ensures continuous operation during low-light conditions.
Seawater pre-treatment typically includes intake screening, media filtration or ultrafiltration to remove suspended solids, antiscalant dosing, and cartridge filtration to protect membranes. AMPAC designs full pre-treatment trains as part of each system.
AMPAC manufactures SWRO systems from 300 GPD for yachts and small vessels up to 500,000+ GPD for municipal desalination plants. Every system is custom-configured to site conditions and water quality.
