“…The objectives are to analyze the proposed designs (based on current state-of-the-art in brackish water RO, FO, and halophyte cultivation) to show the range of conditions where each is feasible and to quantify the main performance parameters in each case. It is anticipated that the proposed approach will be of interest for many environments where salinization is occurring, and where water, energy, and food resources are scarce. , …”

Groundwater salinization is a problem affecting access to water in many world regions. Though desalination by conventional reverse osmosis (RO) can upgrade groundwater quality for drinking, its disadvantages include unmanaged brine discharge and accelerated groundwater depletion. Here, we propose a new approach combining RO, forward osmosis (FO), and halophyte cultivation, in which FO optimally adjusts the concentration of the RO reject brine for irrigation of Salicornia or Sarcocornia. The FO also reuses wastewater, thus, reducing groundwater extraction and the wastewater effluent volume. To suit different groundwater salinities in the range 1−8 g/L, three practical designs are proposed and analyzed. Results include specific groundwater consumption (SGC), specific energy consumption (SEC), wastewater volume reduction, peak RO pressure, permeate water quality, efficiency of water resource utilization, and halophyte yield. Compared to conventional brackish water RO, the results show superior performance in almost all aspects. For example, SGC is reduced from 1.25 to 0.9 m 3 per m 3 of drinking water output and SEC is reduced from 0.79 to 0.70 kW h/m 3 by a FO−RO−FO system treating groundwater of salinity 8 g/L. This system can produce 1.1 m 3 of high-quality drinking water and up to 4.9 kg of edible halophyte per m 3 of groundwater withdrawn.
