The seawater desalination unit is engineered with internationally advanced reverse osmosis (RO) technology and optimized system design.
Compact & Adaptable: Designed to meet shipyard technical specifications, including dimensional constraints and lifting lugs. Features a small footprint, easy installation, and high adaptability for marine vessels and offshore platforms.
User-Friendly: Simple operation and maintenance. Requires only seawater and power supply to produce water after startup.
High Performance: Achieves stable, reliable operation with a salt rejection rate exceeding 98.5%, effectively removing harmful components such as inorganic salts, heavy metal ions, organic matter, bacteria, and pathogens from seawater.
Quality Assurance: Produces water that meets China's National Drinking Water Sanitation Standard (GB5749-2006).
