Salinity Removal Cost Curves for Small to Medium Size Water Wells and Wastewater Effluents
Abstract
Cost curves were developed to evaluate reverse osmosis (RO) vs. electrodialysis reversed (EDR) (0.1 to 2 mgd) followed by thermal brine concentration and evaporation ponds (10 to 600 gpm). The design conditions that have a significant impact on implementation cost were provided as variables in the cost curves to allow flexibility in case-specific applications of the alternatives.The desalting options were evaluated assuming maximum TDS concentration of 600 mg/L in the groundwater or effluent. The limiting factor for RO recovery was anticipated to be silica. Silica species have limited solubility and can precipitate from the concentrate stream, irreversibly fouling an RO membrane. Silica concentrations were grouped into two categories,
