This report documents the activities performed and the results obtained from the arsenic removal treatment technology demonstration project at Rollinsford, New Hampshire. The objectives of the project were to evaluate: (1) the effectiveness of AdEdge Technologies AD -33TM media in removing arsenic to meet the new arsenic maximum contaminant level (MCL) of 10 ig/L; (2) the reliability of the treatment system; (3) the required system operation and maintenance (O and M) and operator skills; and (4) the capital and O and M costs of the technology. The project also characterized water in the distribution system and process residuals produced by the treatment system. The Rollisford, NH demonstration project consisted of two study phases. The source water for both studies consisted of water from two wells having a flow capacity of 95 to 112 gal/min (gpm). Phase 1 of the study utilized an Arsenic Package Unit (APU)-100 system designed for a flowrate of 100 gpm. Because higher flowrates up to 112 gpm were experienced in Phase 1, a 120-gpm APU-RWS system was designed and installed for Phase 2 of the study. Both packages units contained the AdEdge AD-33TM media, which is an iron-based adsorptive media developed by Bayer AG under the brand name of Bayoxide 33.
