SWRO Technology Advantages

99.5% Salt Rejection

High-rejection seawater membranes produce potable water meeting WHO drinking water standards from ocean water.

Energy Recovery

Pressure exchanger devices recover up to 60% of energy, reducing power consumption to as low as 3 kWh/1000 gal.

Corrosion-Proof

Super duplex stainless steel and FRP components withstand harsh marine and coastal environments.

Solar-Hybrid Ready

Off-grid capable with integrated solar power management for remote coastal and island deployments.

Applications

Marine & Yachts

Compact watermakers for vessels of all sizes with automatic flush and standby modes for extended voyages.

Island Communities

Reliable freshwater supply for remote islands with limited groundwater. Solar-hybrid options available.

Coastal Resorts

High-volume desalination for hotels, resorts, and tourism developments along coastlines worldwide.

Municipal Plants

Large-scale SWRO facilities serving cities and towns facing freshwater scarcity and drought conditions.

Frequently Asked Questions

How does seawater reverse osmosis work?

SWRO forces seawater through semi-permeable membranes at high pressure (800-1000 psi), separating salt and contaminants from fresh water. AMPAC systems achieve 99.5%+ salt rejection with energy recovery devices.

What is the energy consumption of a seawater desalination system?

Modern AMPAC SWRO systems with energy recovery consume 3-5 kWh per 1,000 gallons of permeate, significantly less than thermal desalination methods.

Can desalination systems run on solar power?

Yes. AMPAC offers solar-hybrid SWRO systems for off-grid coastal and island installations. Battery storage ensures continuous operation during low-light conditions.

What maintenance does a seawater RO system require?

Regular maintenance includes pre-filter replacement, membrane cleaning (CIP) every 3-6 months, chemical dosing system checks, and high-pressure pump inspection. AMPAC provides remote monitoring and maintenance schedules.

What sizes of seawater desalination systems do you offer?

AMPAC manufactures SWRO systems from 300 GPD for small boats and yachts up to 500,000+ GPD for municipal and resort installations. Every system is custom-configured.
