OEM China Suppliers: Containerized Seawater Desalination Plants from Factory for Instant Off-Grid Water Production Factories, Supplier
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
High salt tolerance with a desalination rate of ≥99.2%; anti-contamination seawater membrane ensuring stable operation at TDS ≤42,000 ppm.
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.
Extreme Environment Adaptability
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
GCC, SASO 2664, ESMA, and ISO certifications meet market access requirements for the Middle East and Central Asia, ensuring seamless international expansion.

Frequently Asked Questions
Q Can it withstand the high temperatures of 55°C in the Middle East?
Equipped with a specialized heat-resistant film and cooling system, it maintains stable long-term operation at 55°C and features dust and sand resistance.
Q Can containers be transported by sea or land?
Standard ISO containers are suitable for global sea and land transport, and can be relocated and reused upon project completion.
Q How are operations and spare parts ensured?
Spare parts warehouses in the Middle East/Central Asia, remote monitoring, and localized engineers with 24/7 on-site response capabilities.
Q What is the salt tolerance and desalination rate of this system?
The system achieves a desalination rate of ≥99.2% and is designed to process feedwater with high salinity levels (TDS ≤42,000 ppm).
Q Does the output water meet direct drinking standards?
Yes, the produced water has a TDS of ≤500 ppm, which fully complies with standard direct drinking water requirements.
Q How fast can the equipment be operational on-site?
Thanks to factory prefabrication and pre-commissioning inside standard 20-foot or 40-foot containers, the system enables immediate on-site operation within 72 hours without complex civil engineering.
