Project Description

The objective of this project is to establish the technical and economic feasibility of the multiphase turbo-expander water desalination process with a cost of water treatment at least 20% less than thermal evaporation. The key component of the proposed process is an expander capable of working with three phases of the expanding fluid: air, liquid (concentrated brine), and solid (ice and salt crystals). A specific objective for the expander development is to demonstrate at least 80% brine freeze in the expander.

Project Benefits

The process developed will be well suited for mobile applications and has potential to reduce treatment costs of high salinity water by at least 20% in comparison to thermal evaporation. The technology developed may have fewer corrosion problems and use less expensive materials than thermal evaporation.
