Marine Sea Water Desalination Plant

Marine Sea Water Desalination Plant | Reverse Osmosis System for Fresh Water Production Onboard

Advanced Reverse Osmosis Technology for Reliable Marine Freshwater Generation

Our Marine Sea Water Desalination Plant utilizes cutting-edge reverse osmosis membrane technology to efficiently convert seawater into high-quality drinking water that meets stringent national standards (GB5749-2006). Designed specifically for marine environments, this system effectively removes minerals, organisms, bacteria, and other impurities from seawater, producing clean, odor-free freshwater ideal for drinking and culinary use aboard vessels and coastal installations.

Engineered with durability and efficiency in mind, our desalination plant features fully automated operation, corrosion-resistant construction, and intelligent monitoring systems—ensuring reliable performance and minimal maintenance in challenging marine conditions.
