Water Chats -- DXV Desalination

February 11, 2009

"Because DXV's system uses 1/3 the energy of current systems, it produces water at half the total cost (capital costs are the same), i.e., $0.50/m3. DXV's cost will ALWAYS be lower than on-shore, high-pressure desal because both technologies use the same filters. It's the method of holding the filters that differs."
