Welcome: Yiwu Weihao Machinery Equipment Company
As a leading manufacturer of industrial water treatment equipment, Yiwu Weihao Machinery Equipment Company specializes in designing and manufacturing **Containerized Seawater Desalination RO Systems**—integrated, modular mobile desalination solutions based on reverse osmosis (RO) technology. All core components are pre-installed, debugged, and integrated into standard shipping containers (20ft/40ft), realizing plug-and-play, rapid deployment, and flexible movement. This system efficiently converts seawater into clean, drinkable freshwater, with high desalination rate, stable performance, and strong adaptability, making it the ideal choice for offshore platforms, coastal areas, islands, emergency disaster relief, and remote marine projects.
Compared with traditional fixed seawater desalination plants, our containerized RO system eliminates the need for on-site civil engineering, shortens construction周期, and can be easily transported by ship, truck, or crane. It integrates pretreatment, RO desalination, post-treatment, and control systems into one container, with small footprint, easy operation, and low maintenance, solving the problem of freshwater scarcity in remote and mobile scenarios.
The Containerized Seawater Desalination RO System achieves efficient seawater desalination through a scientific, integrated workflow, centered on RO reverse osmosis technology, and adapted to containerized modular design:
Seawater Intake & Pretreatment: Seawater is drawn into the container through a dedicated intake system, then filtered by multi-media filters, cartridge filters, and ultrafiltration (UF) membranes to remove suspended solids, algae, colloids, and impurities, protecting the RO membrane from scaling and damage.
High-Pressure Pumping: The pretreated seawater is pressurized by a high-pressure pump to reach the operating pressure required for RO reverse osmosis (50–80 bar), ensuring efficient separation of salt and water.
RO Reverse Osmosis (Core Process): Pressurized seawater flows through high-performance RO membranes, which allow water molecules to pass through while blocking salt ions (sodium, chloride), heavy metals, and other harmful substances, realizing salt-water separation.
Post-Treatment: The desalinated freshwater is treated by disinfection (UV or chlorination) and pH adjustment to meet drinking water or industrial water standards, ensuring water quality safety.
Brine Discharge: The concentrated brine (after desalination) is discharged through a dedicated pipeline, with optional brine concentration treatment to reduce environmental impact, complying with marine environmental protection standards.
Integrated Control: The entire system is controlled by a PLC touch screen, realizing automatic operation, real-time monitoring of water quality, pressure, and flow, with fault alarm and automatic protection functions.
Containerized Modular Design: All components (pretreatment, RO membrane, high-pressure pump, control system) are pre-installed in 20ft/40ft standard containers, plug-and-play, rapid deployment (installation within 3–7 days), easy transportation and movement.
High Desalination Efficiency: Adopts high-performance composite RO membranes, seawater desalination rate up to 99.7%+, TDS of produced water ≤ 500 ppm, meeting WHO drinking water standards and industrial water requirements.
Fully Automatic Operation: PLC + touch screen control system, real-time monitoring of water quality, pressure, flow, and membrane performance; automatic flushing, backwashing, and fault handling, realizing unmanned operation, easy to operate and maintain.
Corrosion-Resistant & Durable: All wetted parts are made of 316L stainless steel or duplex stainless steel, resistant to high-salt seawater corrosion; container is anti-rust, anti-corrosion, and suitable for harsh marine/offshore environments.
Flexible & Scalable: Modular design supports multiple containers parallel connection, expanding water production capacity; customizable 20ft (small-scale) or 40ft (large-scale) containers according to water demand.
Energy-Saving & Environment-Friendly: Optimized high-pressure pump and energy recovery device, reducing energy consumption by 20–30% compared with traditional RO systems; brine discharge meets environmental standards, no secondary pollution.
Strong Adaptability: Suitable for various seawater quality (TDS 35,000–45,000 ppm), adaptable to high temperature, high salinity, and harsh weather conditions, widely used in offshore, coastal, and island scenarios.
