MBR-14: Fouling control in a household MBR plant

MBR technology is potentially an important element in sustainable water resources management. It is a suitable water treatment option with respect to water reuse, especially for individual housings in remote, unsewered areas or in regions suffering from water shortage. In this research project, the fellow will work on the development of an activated sludge wastewater treatment plant with submerged membranes available for decentralized treatment of wastewater from small pollution sources.
In a first phase, fouling control will be investigated under laboratory conditions. Different commercially available membrane materials will be tested in terms of permeability, suitable ways of operation, cleaning and regeneration. The experiments will be carried out in a micro-filtration unit which is operated as a denitrifying activated sludge process. Consequently semi-operation and full-scale operation for selected household MBR will be realised, while applying the identified approaches towards fouling control.
Results of this task concerning laboratory conditions and semi-operation will be the basis for further investigation in research project MBR-8 (Optimisation of full scale MBR operation for decentralised treatment). Moreover, the project aims to set disinfection standards for reuse of non potable water for domestic reuse (toilet flushing), landscape or agricultural irrigation in selected areas.
