ED..EDR..Membrane desalination process would be a more economic option than RO ,with better hydraulic efficiency for high sodium ..brackish water ...combo with nano filtration as a good alternative even to multipass and Combo RO systems,perhaps

A second pass of the RO reject water through a vibrating membrane system will result in a further 15 to 20% reduction in sodium. The reject water from the vibrating membrane would be highly brackish though which you will have to consider how to dispose of. You could pump the reject into drying beds if there is a lot of sun in your region and low humidity.
