MBR-19: Effect of dynamic changes of feedwater on operational parameters within MBRs
TUD |
04/2006 - 03/2009 |
The characteristics of the feedwater have significant impact on the operational process of the MBR. Dynamic changes related to storm water lead to dilution of wastewater and activated sludge. Moreover, run-off material (first-flush), industrial (batch) discharges and changes of wastewater flow and composition due to tourism constitute variable conditions.
The aim of this research project is to determine the effects of the origin of wastewater and activated sludge on filterability, cleaning, recovery, energy and chemicals consumption as well as cost effectiveness. The fellow can draw upon comprehensive information on effects of the origin of wastewater on operation of CAS and MBR from ongoing research programmes on interactions between sewer and wastewater treatment plant.
Additional experimental data gathering (under lab conditions at preferably full scale MBRs: Heenvliet e.g.) will complement the analysis of existing data sets. TUD will provide extensive information on contaminant, solids and particle distribution in wastewater and activated sludge. In co-operation with ongoing research projects particle fractionation and particle sizing techniques will be provided.
