Small Seawater Desalination Equipment

Product Overview

Small Seawater Desalination Equipment is a compact reverse osmosis system designed to convert seawater into clean and usable fresh water for small-scale applications.
Using advanced seawater RO membrane technology, the system efficiently removes dissolved salts, microorganisms, and impurities, providing a stable freshwater supply in areas with limited resources.

This equipment is ideal for islands, coastal villages, ships, resorts, offshore platforms, and emergency water supply.

Working Principle

The system adopts a pretreatment + seawater reverse osmosis process:

  • Pretreatment unit removes suspended solids, turbidity, and organic matter

  • High-pressure pump provides the required pressure to overcome seawater osmotic pressure

  • Seawater RO membranes separate fresh water from salt and contaminants

  • Post-treatment (optional) improves taste and mineral balance

This process ensures high desalination efficiency and reliable operation.
