This paper proposes a new continuous two phase bioreactor (C-TPPB) configuration for theremoval and degradation of xenobiotic compounds from wastewaters.

Abstract

This paper proposes a new continuous two phase bioreactor (C-TPPB) configuration for theremoval and degradation of xenobiotic compounds from wastewaters. The reactor is madeof three principal parts: a tube side in which the wastewater flows; a polymeric membranewhich constitutes the tube walls; a shell side, set as a continuous stirred tank reactor (CSTR),in which the xenobiotics are degraded by means of a bacterial population. A mathematicalmodel for the system description was developed and validated by means of fitting usingliterature experimental data obtained from a similar configuration. Since the nature of thefitting parameters did not depend upon the particular set-up, such validation procedurewas possible. A dimensionless analysis was also carried out by defining a modified Stenton(St’) and Damköhler (Da’) number in order to detect the C-TTPB design criteria. The removalof 4-NtiroPhenol was reported as a case study and an algorithm for a preliminary designprocedure was developed.
