Abstract
Coalbed methane (CBM) or coalbed natural gas (CBNG) is an unconventional gas source with large U.S. and worldwide reserves. CBM wells are screened along coal seams, where water is produced in large volumes to release pressure and allow methane to desorb from the coal surface. The opportunity to utilize produced water as a resource for irrigation, stream flow enhancement or drinking water augmentation is hindered by limited information on CBM produced water treatment. A total of 12 CBM producing wells were sampled in two basins. Three types of pretreatment membranes were utilized for flat sheet studies to observe rejection for the variable water qualities. Constituent rejection and overall downstream water composition were analyzed. Membrane foulant characteristics were analyzed to determine problematic constituents for treatment. The effluent water quality was analyzed to determine the effectiveness of pretreatment membranes to protect downstream desalination processes.
