Flexible and resilient MABR modules
GE Power, Water & Process Technologies
The ZeeLung membrane aerated biofilm reactor (MABR) utilizes a gas-transfer membrane that is specifically designed for MABR applications. Hollow-fiber oxygen-permeable gas-transfer membranes are distributed longitudinally around the circumference of a yarn-based reinforcing core, resulting in a flexible, yet resilient module (photo). The top header delivers and distributes air to the inside of the fiber lumens, and exhaust gas is collected in the bottom header. Modules are installed in cassettes for deployment in bioreactors. ZeeLung cassettes can be installed directly into a bioreactor, and have little effect on existing equipment and operations. In the low-energy process, oxygen is delivered at an efficiency that is said to be four times greater than fine-bubble aeration processes.
