Membrane supported biofilm reactors, a litterature review

Abstract

Membrane supported biofilm reactor is a new technology for biological degredation of pollutants. The utilisation of mebranes as a support for biofilm growth may occure in treatment of several types of wastewater, as removing of nitrogen from municipal wastewater or removing of spesific pollutants from industrial wastewaters. The advantages of such a technology are a better aeration control process than most other biofilm reactors, and the possibility of bubble-free aeration in the removal of VOC compounds. Moreover, for many kinds of treatment like nitrification/denitrification, the MSBR may give a rather compact solution. As the present the major disadvantages of this technology is the lack of knowlegde of the cost of such a membrane and of full scale operation.
