For EWM's first project, EWM  designed  a Full Recovery Desalination®  plant  to use brine from EPWU's  desalination facility and brackish water  from  EPWU’s groundwater wells in the configuration shown above. The process was designed to remove the minerals from brine and brackish water streams and send the clean water back to EPWU for municipal water needs. The minerals that were to be recovered  were  commercial grades of caustic soda, hydrochloric acid, gypsum, and magnesium hydroxide. Total water recovery to EPWU was designed to be approximate 99%, which would benefit EPWU by avoiding brine disposal costs and extending the life of its aquifer.  Due to equipment and other issues during the commissioning stage, the equity that EWM had in the plant was transferred  to another entity. The  new equity owners were given a license to use EWM’s Full Recovery Desalination® technology.
