Membrane bioreactors produce high quality effluents that could be suitable for reuse. However, whentreating high strength wastewater subject to a salinity increase, a modification of biomass characteristicsmay occur. This circumstance is of importance, since it can have a significant impact in terms of biokineticas well as fouling behaviour. The aim of the study was to evaluate the performance of a pilot plant MBR,in terms of biomass activity and membrane fouling, fed with high strength synthetic wastewater, whensubject to a salinity increase. With normal salinity, the pilot plant showed high removal efficiencies andhigh biomass respiratory activity. On the other hand, the salinity increase significantly affected theremoval efficiency as well as the SMP production. Furthermore, the salinity increase showed a strongeffect on biomass activity, reducing in particular the respiration rates of autotrophic populations.
