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).

III.System Functions
Overpressure Protection: Automatically shuts down and triggers audible-visual alarms when high-pressure pump outlet pressure exceeds 6.2 MPa.
Low-Pressure Protection: Activates shutdown and alarms when inlet pressure to the high-pressure pump drops below 0.05 MPa due to insufficient pretreatment water supply.
Multi-Media Filter Cleaning: Equipped with manual multi-way valves for backwashing when differential pressure reaches 0.1 MPa.
RO Membrane Cleaning System: Enables physical, chemical cleaning, and preservation solution injection for membrane modules.
Quality Control: Automatically diverts water discharge if product water quality exceeds standards.
