This paper discusses Zero Discharge Desalination (ZDD) technology as part of a three year project sponsored by the U.S. Bureau of Reclamation. ZDD is able to achieve up to 98% recovery by desalinating brackish groundwater. Testing was performed at several laboratory to evaluate the potential to recover NaCl and other useful salts. Details of the te...

This paper evaluates the combination of enhanced recovery and evaporation processes for technical and economic feasibility, commenting on the advantages and disadvantages. The Zero Discharge Desalination (ZDD) process demonstrated in Alamogordo and the proposed Advanced Purified Water Treatment Plant (APWTP) at El Paso Water Utilities (EPWU) ) wil...

This paper describes the Zero Discharge Desalination design process and optimization done at the University of Texas at El Paso, as well as plans for pilot testing in Honduras in 2016. The target was to produce 250 liters of drinking water with less than 600 mg/L total dissolved solids (TDS) and 8000 liters of irrigation water with no more than 55...
