Coupling process of catalytic membrane with AOP for fouling and OMPs removal

Ceramic ultrafiltration is a promising technology for water reclamation, but issues with membrane fouling and the removal of organic micro-pollutants have limited its development. Recent research has shown that catalysis-based ultrafiltration has the potential to address these problems. In this study, catalysis-modified (CuFe2O4 and Pd)...

Enhancing performance of ultrafiltration with inline dosing of coagulant and powdered activated carbon: Effect on fouling and removal of organic micropollutants including poly- and perfluoroalkyl substances

In this study simultaneous and continuous inline dosing of PAC and coagulant in UF was investigated. Surface water was directly treated with PAC-UF and performance of the system was assessed by looking at membrane fouling and organic micropollutants removal. Combining adsorption and membrane processes in one technique, hybrid membrane processes,...

Purifying IJssellake water: Operation and performance analysis of direct hollow fiber nanofiltration on raw IJssellake water

The aim of this research was to evaluate the feasibility of direct hollow fiber nanofiltration membranes for drinking water purposes. The experiments were performed on the dNF40 pilot provided by NXF. The fouling potential and the ion retention of the dNF40 pilot were determined by continuous filtration experiments using raw IJssellake water...

Adsorption of organic micro pollutants with high silica zeolite in secondary wastewater effluent: Competition between OMP and NOM

This work investigated which NOM fraction from secondary wastewater effluent were causing competition with metoprolol and clarithromycin for adsorption site on high silica zeolites (HSZ). This thesis works with five commercially available HSZ frameworks (FAU, MOR, BEA, MFI and FER). Adsorption batch test were performed with demi water,...

Influence of variation in the natural water quality matrix on advanced oxidation processes

In this master thesis research the influence of the variation in the natural water quality matrix on advanced oxidation processes, considering organic micropollutant degradation and bromate formation, has been recearched with a pilot plant installation at drinking water company Dunea. The pilot plant installation consists of serial peroxone (O3...

Underwater ultra-wideband fingerprinting-based localization

In this work a new location fingerprinting-based localization algorithm is proposed for an underwater medium by utilizing ultra-wideband (UWB) signals. In many conventional underwater systems, localization is accomplished by utilizing acoustic waves. On the other hand, electromagnetic waves haven't been employed for underwater localization due...

Degradation of organic micropollutants by advanced oxidation through UV/H2O2

Drinking water company Dunea Duin en Water produces drinking water from the Meuse River, which contains a variety of organic micropollutants (OMPs) from upstream activity. OMPs found in Dunea’s source are plant protection products, pharmaceuticals, hormones and endocrine disruptors and X-ray contrast media. Continues development of measuring...

Performance assessment of different pre-treatment techniques for the advanced oxiation process

Dunea Duin en Water provides drinking water for 1.2 million people in de western part of the province Zuid-Holland. As a source, for their drinking water production, surface water from the river Meuse is used. Organic micro pollutants (OMPs), although in extremely low concentrations, have occasionally been detected in the river Meuse. Obviously,...
