What is it about?
The incorporation of membrane separation technology into anaerobic processes (such as the UASB reactor) represents an important innovation in the development of wastewater treatment engineering, especially when water reuse is desired. This research consisted of the evaluation of microfiltration through submerged membranes, provided with a backwash system, during the continuous treatment of UASB reactor effluent operating with sanitary sewage. The membranes used were of the hollow fiber type fabricated with the poly (ether-imide) polymer. In conclusion, the long-term experiments carried out revealed that the microfiltration removal of the UASB reactor effluent was 87% for BOD, 84% for COD, 99% for SST, and 2.02 log units for Fecal Coliforms.

Why is it important?
This paper shows that the complementary treatment of UASB reactors effluents by membrane filtration can improve the quality of these effluents in order to attending environmental standards.
Perspectives
We expect that the costs of membrane treatment will decrease so that this kind of treatment can be used in association with UASB Reactors.
