Coal-bed methane (CBM) is an increasingly important source of natural gas. Current production levels within the U.S. exceed 970 bcf/year. Disposal of produced water from CBM production can be expected to be a continuing problem for the foreseeable future. However, the high cost of water disposal and lack of efficient technology for treatment are barriers to expanded development of CBM reserves. Many of the areas where CBM is produced are arid or semi-arid and can benefit from creation of additional water supplies. If the water from CBM can be economically and efficiently treated to make it acceptable for surface discharge, it becomes a resource instead of a waste. Benefits can be achieved through both agricultural uses and domestic uses depending on the quality of the treated water which can be achieved. Treatment for surface discharge currently requires the application of reverse osmosis (RO) technology. This proposal will demonstrate the effectiveness of capacitive deionization (CDI) technology for the treatment of CBM produced water. This technology should prove to be more reliable and cost effective than RO. In addition, CDI uses approximately 1/10 of the energy of RO and has a significantly smaller secondary waste stream than RO in this application.
