Membrane Bioreactors (MBR) and Reverse Osmosis (RO) for Leachate Treatment

This paper describes four pilot studies that were conducted to evaluate the Membrane bioreactor (MBR) process for leachate treatment. Both hollow fiber and cross-flow systems from several vendors were evaluated. One system also includes application of RO following the MBR process as a polishing step. Data from these systems highlight biological performance, capabilities, effluent quality and operational considerations such as membrane flux, fouling and trans-membrane pressure (TMP).
