Salton Sea Desalination

The current project is located at California's largest lake, the Salton Sea. This body of water is about 30% more salty than the ocean making it difficult to desalinate using commonly used technologies such as reverse osmosis (RO) or multi-stage flash (MSF). The combination of Vertical Tube Foam Evaporation (VTFE) and Dispersed Seeded Slurry Evaporation (DSSE) technology patented by Hugo Sephton is well suited to desalinating this challenging body of water.
