Seawater Desalination Vessel Shipyard

Product Introduction: 10 Ton/Day Single-Stage Seawater Desalination Unit (Compact Marine Model)

I. Product Overview

This unit is a small, integrated, single-stage seawater desalination system utilizing reverse osmosis (RO) technology. It is specifically designed for applications where space is limited and water demand is moderate. Featuring an ultra-compact, integrated frame design, the unit offers a minimal footprint, low power consumption, easy installation, and fully automatic operation. It represents a highly cost-effective desalination solution for fishing vessels, speedboats, island cabins, coastal temporary work sites, and small offshore platforms.

The system directly draws in seawater or brackish water and employs a high-pressure reverse osmosis process to remove salt, sediment, colloids, bacteria, and impurities. It produces potable water that meets quality standards, reliably satisfying daily needs for drinking, washing, and general domestic use.

III. Structural and Configuration Features

1. Ultra-Compact Design
The unit measures only 1 meter in length and 0.6 meters in width—making it the smallest model on the market for this output capacity. It saves space, is easy to transport, and is ideal for installation in ship cabins, small equipment rooms, and other confined areas. 2. Low-Power, Energy-Efficient Operation
With a total power consumption of only 5 kW, the unit offers significant energy savings compared to conventional 10-ton seawater systems. It is suitable for both continuous long-term operation and intermittent start-stop cycles, ensuring very low long-term operating costs.
3. Comprehensive Pre-treatment System
Equipped with multi-media and precision filtration systems, it effectively removes sediment and suspended solids from the seawater. This protects the high-pressure pump and reverse osmosis membranes, significantly extending the equipment's service life.
4. Intelligent Operation
Features one-touch startup, automatic water production, automatic shutdown, and scheduled automatic membrane flushing. It requires no dedicated personnel for monitoring, prevents membrane scaling and clogging, and is maintenance-free for daily use.
5. Seawater-Specific Anti-Corrosion Design
The entire system utilizes high-pressure, salt-spray, and corrosion-resistant piping and pumps. Specifically engineered for harsh coastal environments characterized by high salinity and humidity, the equipment is highly resistant to rust and malfunctions. IV. Effluent Water Quality

The single-stage seawater reverse osmosis process effectively removes the vast majority of salts and impurities from seawater. The resulting water is clear, odorless, and free of salty taste, fully complying with the GB5749-2022 standard for drinking water. It is suitable for:

- Daily drinking water for personnel
- Domestic use (washing, food preparation)
- Equipment make-up water and small-scale aquaculture supply

V. Application Scenarios

- Freshwater supply for fishing vessels, workboats, and marine transport vessels
- Water supply for small island guesthouses and campsites
- Coastal construction sites, temporary project offices, and field operation sites
- Water intake for small offshore platforms and floating platforms
- Water purification upgrades in areas with brackish water

VI. Key Product Advantages

1. Ultra-compact: Footprint of only 0.6 m²; the ideal choice for space-constrained environments
2. Ultra-low energy consumption: 5 kW low power rating; energy-efficient and cost-effective for long-term operation
3. Simple installation: Factory-integrated unit; ready to use upon connection to water and power
4. Stable and durable: Specialized anti-corrosion configuration for seawater; resistant to salt spray and corrosion
5. Maintenance-free operation: Fully automatic running with intelligent protection and low failure rates
