Modular Geothermal Desalination Unit (MGDU)
The MGDU aims to achieve the distillation of brackish and/or sea water, using energy from a low enthalpy geothermal reservoir (temperatures below 90 °C).
The operating process is a modification of a conventional MED system, using hot water instead of steam and driving it through all the evaporation chambers. One of its main challenges is the achievement of a reliable design able to mitigate the corrosive effects of salt water and the geothermal fluid.
In a first approach, this technology will be applied to desalinate seawater in Baja California, due to the availability of both resources: seawater and geothermal reservoirs. Currently in its experimental Stage, one of the goals for this plant is the production of distilled water from seawater with a maximum concentration of 35,000 ppm.
