Seawater RO System

Main Application:

Industrial seawater RO desalination system engineered for large-scale coastal and offshore applications, ensuring reliable freshwater supply with high efficiency, corrosion resistance, and optimized energy performance.

Seawater Reverse Osmosis (SWRO) Desalination System

A Seawater Reverse Osmosis (SWRO) Desalination System converts seawater into fresh usable water through high-pressure membrane separation technology.

CHONGYANG WATER provides customized SWRO desalination systems for coastal cities, islands, resorts, offshore platforms, power plants, mining operations, municipalities, and industrial facilities.

What Is a SWRO Desalination System?

A SWRO system removes dissolved salts and impurities from seawater by applying high pressure to specialized seawater RO membranes. It is suitable for seawater with high TDS levels, typically around 35,000–45,000 ppm.
