To inform the public.
Description:
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-in-diameter by 72-in-tall pressure vessels configured in parallel. Each resin vessel contained 50 ft3 of a strong base anionic exchange resin, i.e., A300E manufactured by Purolite. The objectives of the project are to evaluate the effectiveness of Kinetico ion exchange (IX) system in removing arsenic and nitrate to meet the new arsenic maximum contaminant level (MCL) of 10 ug/L and the existing nitrate MCL of 10 mg/L as N. Additionally, this project evaluates the reliability of the treatment system (Arsenic Package Unit [APU]-250), the required system operation and maintenance (O&M) and operator skill levels, and the capital and O&M cost of the technology. The project also characterizes the water in the distribution system and process residuals produced by the treatment process.
