  1. seawater desalination energy consumption

     

    Dear Rhiannon:

    The energy needed for seawater desalination typically ranges between 2.5 and 3.7 kWh/cubic meter of fresh water and averages 3.0 kWh/cubic meter. Brackish water desalination plants use approximately 20 to 50 % of this energy. The Desalination Group library contains presentation that provides greater detail on the energy used for desalination -
