The influence of nitrate and chloride concentrations on the selectivity of nitrate transport in the IEMB process was investigated. With appropriate dosing of chloride ions to the IEMB biocompartment, it was possible to regulate the net bicarbonate flux in the system, thus maintaining the bicarbonate concentration in the treated water at the desired level. The latter was not possible to achieve in Donnan dialysis, operated as a single process in which, besides the lower nitrate removal efficiency found, bicarbonate was co\u2010extracted together with nitrate from the polluted water stream. Residual carbon source (ethanol) and nitrite were not detected in the treated water produced in the IEMB system. With a concentration of nitrate in the polluted water three times higher than the maximum contaminant level of 50 mg L\n                    <jats:sup>\u22121<\/jats:sup>\n                    allowed, the IEMB process was successfully operated for a period of 1 month before exceeding this limit.\n                  <\/jats:p>","DOI":"10.1021\/bp010160u","type":"journal-article","created":{"date-parts":[[2002,7,26]],"date-time":"2002-07-26T02:08:28Z","timestamp":1027649308000},"page":"296-302","source":"Crossref","is-referenced-by-count":27,"title":["Ion Exchange Membrane Bioreactor for Selective Removal of Nitrate from Drinking Water: Control of Ion Fluxes and Process Performance"],"prefix":"10.1002","volume":"18","author":[{"given":"Svetlozar","family":"Velizarov","sequence":"first","affiliation":[]},{"given":"Jo\u00e3o G.","family":"Crespo","sequence":"additional","affiliation":[]},{"given":"Maria A.","family":"Reis","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2008,9,5]]},"reference":[{"key":"e_1_2_6_2_2","doi-asserted-by":"publisher","DOI":"10.1002\/j.1551-8833.1993.tb05966.x"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.1002\/j.1551-8833.1992.tb07430.x"},{"key":"e_1_2_6_4_2","doi-asserted-by":"publisher","DOI":"10.1061\/(ASCE)0733-9372(1997)123:4(371)"},{"key":"e_1_2_6_5_2","first-page":"61","volume-title":"Ion exchange Technology: Advances in Pollution Control","author":"Guter G.
