摘要: This report documents the activities performed during and the results obtained from the first six months of the performance evaluation of a Kinetico ion exchange (IX) system to remove arsenic (As) and nitrate from source water at the City of Fruitland in Idaho. The 250-gal/min (gpm) IX system consisted of a bank of five sediment filters and two 48-inch-diameter by 72-inch-tall pressure vessels configured in parallel. Each resin vessel contained 50 feet of a strong base anionic exchange resin, i.e., A300E manufactured by Purolite. The system installation first began in March 2004; however, the commencement of the system operation was repeatedly delayed until June 2005 due to a series of problems encountered. The problems started with excessive sediment production from the original supply well, followed by the failure of a replacement well to pass bacterial testing even after repeated sanitation efforts. The problems were further compounded by the need to replace the resin that was erroneously installed in the resin vessels and a broken well pump that was salvaged from the original supply well into the replacement well. / Supplementary Notes: Sponsored by National Risk Management Research Lab., Cincinnati, OH.
