Shuangliang Seawater Desalination

Low Temperature-Multi Effect Distillation (MED) for seawater desalination refers to a desalination technology where the highest brine temperature (TBT) does not exceed 70°C, characterized by a series of horizontal (or vertical) tube falling film evaporators connected in series and divided into several effect groups. A certain amount of steam is inputted through multiple evaporation and condensation cycles, resulting in distilled water multiple times the amount of heating steam.

Technical Features:

Adaptability to different high and low-grade waste heat situations, improving overall efficiency.
Low operating temperature to avoid or reduce equipment corrosion and scaling.
No need for complex pretreatment of seawater, suitable for various changes in seawater conditions.
Stable and reliable device operation, with low maintenance and repair requirements, and low cost.
Strong load adaptability, with an adjustment range of 40% to 110%.
High product water quality with a salt content lower than 5mg/L.

Application Scenarios:

Suitable for large and medium-sized seawater desalination plants utilizing high and low-grade steam provided by power plants and chemical plants, especially suitable for utilizing low-grade waste heat.

The product water has extremely high purity and can be used as boiler makeup water, process water in production processes, or for large-scale municipal drinking water supply.
