Project Summary

  • Desalination of brackish groundwater using Reverse Osmosis and Electrodialysis Reversal is expensive

  • Certain metals found in brackish groudwater build up on desalination membranes

  • Brackish groundwater is found in many regions, including New Mexico

  • Pretreatment by removing aluminum, iron, and manganese from the brackish water before desalination could reduce desalination costs

  • Built a bench-scale model for our proposed full-scale pretreatment process

  • Process is simple and energy efficient so it can be used in rural areas
