Membrane-attached biofilms for VOC wastewater treatment. II: Effect of biofilm thickness on performance.


This article reports a study of the performance of membrane-attached biofilms grown in a single tube extractive membrane bioreactor (STEMS) used for the treatment of a synthetic wastewater containing a toxic VOC (1,2-dichloroethane [DCE]). Mass balances show that complete mineralization of DCE was achieved, and that the biofilms were effective in reducing… (More)
