Abstract:

This study introduces the novel HAMBgR process Hybrid Adsorption Membrane Biological Reactor and presents an application for the efficient removal of perchlorate from contaminated waters. This process combines the economic advantages of a microbiological treatment with the reliability of a physicochemical process. Batch isotherm experiments show that the ion-exchange adsorbents from this study can be effectively and continuously regenerated biologically in a single membrane bioreactor that is used for treating perchlorate contaminated waters. The presence of the ion-exchange resin in the HAMBgR process provides a physicochemical backup to the biological process that was shown to reduce effluent perchlorate spikes by up to 97 in comparison to a conventional MBR that was subject to sudden changes in influent conditions.
