Direct Membrane Filtration-A new concept for municipal wastewater treatment

Lipnizki, Frank LU orcid and Hey, Tobias LU (2022) 3rd International Conference for Membrane Technology and Its Applications, 2022
Abstract
Direct Membrane Filtration (DMF) is a relatively new concept for the treatment of municipal wastewater. While the widely established membrane bioreactor (MBR) concept combines biological treatment with membrane separation, the DMF concept operates abiotic. The DMF concept is particularly suited treating municipal wastewater having only BOD and total phosphorous (Ptot) discharge demands. Furthermore, the DMF concept has been evaluated and indicated the potential to operate with less energy and on a smaller
footprint, less environmental impact than conventional wastewater treatment. The given presentation will reflect on the results from three large scale DMF pilot units in Scandinavia: (1) Lund, Sweden (1 m²), and (2) Svedala, Sweden... (More)
Direct Membrane Filtration (DMF) is a relatively new concept for the treatment of municipal wastewater. While the widely established membrane bioreactor (MBR) concept combines biological treatment with membrane separation, the DMF concept operates abiotic. The DMF concept is particularly suited treating municipal wastewater having only BOD and total phosphorous (Ptot) discharge demands. Furthermore, the DMF concept has been evaluated and indicated the potential to operate with less energy and on a smaller
footprint, less environmental impact than conventional wastewater treatment. The given presentation will reflect on the results from three large scale DMF pilot units in Scandinavia: (1) Lund, Sweden (1 m²), and (2) Svedala, Sweden (183 m²) and (3) Fredrikstad, Norway (386 m²). These pilot operations show that the DMF concept can achieve high particulate COD and P tot rejections. The high carbon rejection results to a significant increased biogas production in comparison to conventional primary sludge resulting in an energy neutral/positive wastewater treatment process. Furthermore, results from fouling and cleaning studies to optimize the membrane performance will be presented. Overall, the research shows that the DMF has potential to be applicable for decentralized wastewater treatment or significantly reducing the organic load to the biological treatment step in areas with a high population.
