Zhongnuo Water Treatment designed and supplied a 12 m³/h containerized seawater desalination system for a steel plant in Algeria. The system converts seawater into high-quality potable water for employees and daily plant use. By integrating SWRO technology with an Energy Recovery Device (ERD), the project provides reliable freshwater while reducing operating costs and ensuring stable operation in a harsh coastal environment.

• High-salinity seawater with strong corrosiveness.
• Reliable drinking water supply for workers.
• Remote coastal installation environment.
• Continuous 24/7 operation.
• Reduced energy consumption and maintenance costs.

Seawater Intake  ->  Raw Water Tank  ->  Raw Water Pump  ->  Biocide Dosing System  ->  Multi-media Filter  ->  Activated Carbon Filter  ->  5 μm Cartridge Filter  ->  High-pressure Pump + Energy Recovery Device (ERD)  ->  SWRO Seawater Desalination Membrane System  ->  Fresh Water Tank  ->  UV Sterilizer  ->  Water Supply System  ->  Potable Water Distribution Points

The complete desalination plant is integrated into a 40HQ container, including pretreatment, SWRO membranes, ERD, UV sterilization, PLC automatic control, and online monitoring. The modular design minimizes installation time and provides reliable freshwater for industrial facilities.

Q: Why use SWRO instead of BWRO?
A: SWRO is specifically designed for seawater with high salinity.

Q: Why install an ERD?
A: It recovers hydraulic energy and lowers operating costs.

Q: Can the system provide drinking water?
A: Yes, after desalination and UV sterilization, subject to local standards.

Q: Is the system suitable for steel plants?
A: Yes, especially for coastal industrial facilities.

Q: Can the container be relocated?
A: Yes, the modular design allows easy transportation.

Q: How long do SWRO membranes last?
A: Typically 3–5 years with proper maintenance.

Q: Can the capacity be customized?
A: Yes, from 1 to over 1,000 m³/h.

Q: Does Zhongnuo provide commissioning?
A: Yes, including installation guidance, training, and after-sales support.
