Horizontal Seawater Desalination | Multi-Voltage Offshore Water System

I. Product Overview

This horizontal seawater desalination unit utilizes proven reverse osmosis (RO) technology. It features a compact, stable, integrated horizontal frame design with a small footprint and supports global multi-voltage power supplies. The equipment purifies seawater, brackish water, and high-salinity surface water, producing output that meets the GB 5749-2022 national standard for domestic drinking water (tap water).

The unit integrates pre-treatment, a high-pressure system, an RO membrane assembly, and a control system into a single package. It is fully commissioned at the factory and ready for operation upon connection to water and power sources. It is suitable for applications such as fishing vessels, small islands, offshore platforms, coastal guesthouses, remote offshore operations, and emergency water supply, providing a stable and safe source of drinking water in water-scarce offshore environments.

III. Output Water Quality Description

The equipment utilizes reverse osmosis membranes for high-efficiency desalination, removing salts, heavy metals, sediment, colloids, bacteria, microorganisms, and impurities causing odors or off-flavors from the seawater. The output water meets the GB 5749-2022 standard for drinking water:

1. Sensory Indicators: The output water is clear and free of turbidity; the bitter, salty taste of seawater is removed, resulting in a pleasant taste.
2. Physicochemical Indicators: Effectively removes dissolved salts and heavy metal ions; the produced fresh water is suitable for drinking, cooking, and personal hygiene.
3. Microbiological Indicators: Filters out and removes pathogenic bacteria, ensuring safety for direct human consumption.
4. Suitable for use as domestic drinking water and for small-scale production applications. IV. Core Product Advantages

1. Compact horizontal structure for flexible installation

Featuring a horizontal frame design with dimensions of 80×60×60 cm, the unit offers a small footprint and a low center of gravity, resulting in minimal vibration during operation. It is ideal for placement in ship cabins, equipment rooms, and confined spaces. The integrated, all-in-one design eliminates the need for complex on-site assembly; simply connect water and power upon delivery to begin operation.

2. Global voltage compatibility for international use

Supports a wide voltage range (220–380–440V, 50–60 Hz), making it compatible with power grids in China, Southeast Asia, Europe, and the Americas—an excellent choice for export and overseas projects. With a power rating of 2 kW, it is energy-efficient and suitable for prolonged, continuous operation.

3. Stable daily output of 1.5 tons to meet small-to-medium water needs

Produces 1.5 tons of fresh water daily, satisfying the drinking water requirements of small fishing vessels, island guesthouses, and small offshore work sites. The system includes pressure protection, high/low-pressure alarms, and automatic shutdown upon detecting anomalies, ensuring stable, reliable operation and minimizing the risk of failure.

4. Comprehensive reverse osmosis purification ensuring safe, compliant water quality

The complete system integrates pre-treatment filtration, a high-pressure pump, and seawater RO membrane modules for deep desalination. Corrosion-resistant piping and fittings are used to withstand harsh marine environments and extend equipment lifespan, while the output water meets standards for potable tap water.

5. Simple operation and easy maintenance

Equipped with a fully automatic control system that begins water production immediately upon startup. No complex professional operation is required; routine maintenance involves only the periodic replacement of pre-treatment filter cartridges. With low maintenance costs, the system is suitable for daily management by non-specialist personnel. V. Application Scenarios

- Daily drinking water supply for small-to-medium fishing vessels, yachts, and marine workboats
- Water supply for small island residences, seaside guesthouses, and offshore vacation spots
- Small offshore drilling platforms and remote offshore construction sites
- Water supply for coastal areas with brackish water and for emergency disaster relief
- Small-scale overseas seawater desalination projects; compatible with various international voltage standards

VI. Product Summary

This horizontal seawater desalination unit—with a daily capacity of 1.5 tons—is a compact, fully automated, all-in-one system compatible with multiple voltages. Its horizontal design saves space, and it supports global voltage standards, converting seawater into direct-drinking-quality tap water that meets national standards. Offering stable operation and easy maintenance, it serves as a cost-effective desalination solution for small-to-medium-scale marine, island, and offshore applications.
