Membrane Bioreactor (MBR)

The technology that provides increased capacity and improved treatment efficiency

Many treatment plants need not only deal with increased loads due to population increase, connection of new areas, etc. but also have to meet more stringent requirements for removal of traditional pollutants such as oxygen-consuming substances and nutrients and possibly micropollutants. With the help of a Membrane BioReactor (MBR), it is possible to handle both increased biological and hydraulic load, as well as increased treatment requirements, and this usually in existing volumes. Henriksdal wastewater treatment plant in Stockholm is one of the facilities that faces these challenges and, in addition, does not allow for expansion of the existing plant.

For many years we have worked with Membrane BioReaktor (MBR) and its various technical designs (flat-sheet and hollow fibers). Together with Stockholm Water and Waste Company, we have built a pilot copy of Henrikdal's future treatment plant including a sludge management pilot (mesophilic and thermophilic digestion). An advantage of MBR technology is that particles and particulate pollutants cannot pass. The technology allows for a simple post-treatment and further purification of waste water from, for example, pharmaceutical residues. We have also been working on this for several years, both using the pilot plant at Hammarby Sjøstadsverk and at full-scale WWTPs.
