China China Suppliers: Factory-Integrated Containerized Seawater Desalination Plants for Instant Water Production Factories, Manufacturers
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 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.
Extreme Environment Adaptation
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 for harsh Middle East & Central Asia operations.
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 ensure seamless international expansion and meet market access requirements across the Middle East and Central Asia.

Application Scenarios
Frequently Asked Questions
Can the equipment withstand the extreme temperatures of 55°C in the Middle East?
Equipped with specialized heat-resistant membranes, high-efficiency cooling, and thermal insulation, the system maintains stable long-term operation from -20°C to 55°C, with built-in dust and sand protection.
Can the containers be transported by standard sea and land logistics?
Yes, the systems are fully integrated into standard 20-foot and 40-foot ISO containers, engineered for seamless sea, rail, and road transportation, and can be easily relocated and redeployed across different project phases.
How are on-site operations and replacement spare parts ensured?
We maintain dedicated spare parts warehouses in the Middle East and Central Asia, supported by 24/7 intelligent remote monitoring and regional field service engineers capable of rapid on-site dispatch.
How fast can the desalination unit begin water production once delivered to the site?
Because the system undergoes full factory prefabrication and wet pre-commissioning, on-site commissioning is completed within 72 hours, reducing civil construction work by 80% and overall project duration by 60%.
What standard of water quality does the containerized SWRO system produce?
The system processes raw seawater with inlet TDS up to 42,000 ppm at a desalination rate of ≥99.2%, producing clean permeate water with TDS ≤500 ppm, fully compliant with international direct drinking water standards.
Which regional compliance standards and certifications are met by this equipment?
The equipment strictly adheres to international and regional codes, certified under GCC, SASO 2664, ESMA, and ISO standards to guarantee unhindered regulatory compliance and market access in the Middle East and Central Asia.
