International Conference on Membrane assisted Water Purification
- Abstract
- Two new membrane concepts have been piloted have been piloted in in recent years at Lund University in Sweden – namely (1) direct membrane filtration (DMF) and (2) water harvesting. Both concepts use submerged membranes as the established membrane bioreactor (MBR) concept but they exclude a biological treatment. This presentation will showcase the latest developments and experiences with these two new concepts.
The DMF concept operates abiotically and offers an interesting alternative for municipal wastewater treatment. In this approach, municipal wastewater undergoes physico-chemical pretreatment, including coagulation, flocculation, and microsieving, prior to membrane treatment. With its high carbon rejection, the DMF concept...

Both concepts use submerged membranes as the established membrane bioreactor (MBR) concept but they exclude a biological treatment. This presentation will showcase the latest developments and experiences with these two new concepts.
The DMF concept operates abiotically and offers an interesting alternative for municipal wastewater treatment. In this approach, municipal wastewater undergoes physico-chemical pretreatment, including coagulation, flocculation, and microsieving, prior to membrane treatment. With its high carbon rejection, the DMF concept can significantly boost biogas production, resulting in a potentially energy-neutral or positive wastewater treatment process. Additionally, the DMF process requires a smaller footprint compared to conventional wastewater treatment technologies. Three pilot installations in Sweden and Norway have demonstrated the potential of this concept.
The water harvesting concept aims to upgrade storm- and rainwater collected from various sources, such as stormwater ponds, house roofs, and parking lots, for reuse in non-drinking applications like toilet flushing and garden watering. In this case, the water undergoes pre-screening and polishing with submerged membrane modules to remove micropollutants and microplastics. Results from a pilot installation in Sweden connected to a stormwater pond will highlight the capacity of this concept.
Overall, this presentation will highlight the potential of submerged membrane modules in two new concepts beyond the widely established used in MBRs.
