Thermal Processes

Thermal processes separate fresh water from salt water by boiling or freezing. Reclamation research has taken thermal desalination to a new level by funding research to quantify theoretical energy required for desalination and where energy is lost in the process, developing membrane distillation, investigating salinity gradient solar ponds as heat source, and examining clathrate formation to aid in harvesting fresh water ice crystals from deep below the sea. Research topics in thermal processes include:
