China China Suppliers: Factory-Direct Containerized Seawater Desalination Plants for Efficient Mobile Water Solutions Factory, Suppliers
Product Description
Our Solution
Shanghai Tongjie Environmental Protection's containerized seawater desalination equipment is specifically designed for the Middle East, Central Asia, islands, oil fields, and remote camps. It employs seawater reverse osmosis (SWRO) technology combined with energy recovery and high-temperature resistant, anti-contamination membranes, achieving a TDS tolerance of up to 42,000 ppm and producing water with TDS ≤500 ppm (compliant with direct drinking standards). The system integrates 20-foot/40-foot standard containers, featuring factory prefabrication and pre-commissioning, enabling immediate on-site operation within 72 hours without complex civil engineering work. It operates effectively in temperatures ranging from -20°C to 55°C, offering corrosion-resistant, explosion-proof capabilities and remote monitoring functionality.
Core Advantages
High Salt Tolerance with a Desalination Rate
High salt tolerance with a desalination rate of ≥99.2%; anti-contamination seawater membrane ensuring stable operation at TDS ≤42,000 ppm and a desalination rate ≥99.2%.
Container Gantry Installation
Standard container integration enables 72-hour commissioning, reducing civil construction by 80% and project duration by 60%, with immediate water supply upon site delivery.
Adapted to Extreme Environments
Suitable for desert and marine applications with heat resistance up to 55°C, cold resistance down to -20°C, salt spray protection, and explosion-proof design.
Intelligent Operation and Maintenance
Unmanned PLC + touchscreen + remote monitoring, available 24/7 with fault alerts and dual control options (local/remote).
Comprehensive Compliance Certifications Ensure Seamless International Expansion
GCC, SASO 2664, ESMA, and ISO certifications meet market access requirements for the Middle East and Central Asia.

Frequently Asked Questions (FAQ)
A Equipped with a specialized heat-resistant film and heavy-duty cooling system, it maintains stable long-term operation at 55°C and features comprehensive dust and sand resistance.
A Yes, standard 20-foot and 40-foot ISO containers comply with international logistics standards, suitable for intermodal sea and land freight, and can be easily relocated and reused upon project completion.
A We maintain dedicated spare parts warehouses in the Middle East and Central Asia, along with 24/7 remote monitoring and localized engineers providing on-site support.
A The standard unit provides processing capacities ranging from 100 to 1,000 tons per day. Customized scalable configurations are available to meet larger demand requirements.
A Yes. With a desalination rate ≥99.2%, the produced water achieves TDS ≤500 ppm, fully compliant with international WHO and regional standards (GCC/SASO) for direct drinking.
A Because each container undergoes 100% factory prefabrication and pre-commissioning, plug-and-play operation and water production can begin within 72 hours of arrival without major civil works.
