Removal Of Trace Organic Chemicals By Membrane Bioreactors And Hybrid Processes, Kaushalya Chandrakanthi Wijekoon
University of Wollongong Thesis Collection 1954-2016
Membrane bioreactors (MBRs) can effectively remove a wide range of trace organic contaminants (TrOCs), yet their fate and recalcitrant contaminant removal during MBR treatment is uncertain. This study focused on revealing the fate and removal of TrOCs during MBR treatment, membrane distillation (MD) and novel membrane distillation bioreactor hybrid treatment (MDBR). It also aimed to elucidate the effect of physicochemical properties (namely, molecular structure, log D, and volatility) on the fate and removal of TrOCs during MBR, MD and MDBR treatment. The effect of molecular properties on the fate of trace organic contaminants in the aqueous and solid phases during …

The occurrence of trace organic contaminants (TrOCs) in raw and secondary treated effluent is of significant human and ecological health concern, particularly with regard to the safety of the downstream production of water for human consumption. Efficient removal of TrOCs is a prerequisite to wastewater reclamation which is regarded as an important means of tackling the ever increasing demand for water. This thesis work investigated the removal of TrOCs by wholecell white rot fungi (WRF) and their extracellular enzyme (i.e., laccase) in membrane bioreactors (MBRs) and enzymatic membrane reactors (EMRs).
Nutrients And Trace Organic Contaminants Removal By An Anoxic-Aerobic Membrane Bioreactor (Mbr): Lab-, Pilot- And Full-Scale Investigations, Hop Van Phan
University of Wollongong Thesis Collection 1954-2016
Increasingly stringent environmental regulations and freshwater shortage are key drivers for a worldwide trend of introducing advanced technologies for wastewater treatment, particularly in removing nutrients (i.e., nitrogen and phosphorous) and trace organic contaminants (TrOCs). Membrane bioreactor (MBR) is a compact process that employs membranes for effective solid-liquid separation, which in turn brings about additional advantages such as decoupling of hydraulic retention time (HRT) and sludge retention time (SRT), maintenance of higher mixed liquor solids concentration (MLSS) than the conventional activated sludge (CAS) process and potentially better removal of resistant contaminants in a single step. The anoxic-aerobic MBR process combines bioreactors …
