A sponge-based moving bed bioreactor for micropollutant removal from municipal wastewater
… the past few decades, the frequent detection of micropollutants in the aquatic environment has raised particular health and environmental concerns. Wastewater treatment plants (WWTPs) serve as significant barriers to reduce the release of micropollutants. However, due to the diverse …

The Role of Pore Size Distribution in Competitive Adsorption on Activated Carbon
… that in order to minimize the impact of NOM on micropollutant adsorption capacity and adsorption kinetics, the adsorbent must have a wide range of micropore sizes, including pores of similar size to the target compound.

The use of a calibrated three phase (solid-aqueous-gas) plant-wide wastewater treatment model to simulate data on mineral precipitation
… chemicals, extensive use, and the release of micropollutants into the environment are inevitable occurrences in contemporary society. In reality, wastewater treatment plants are the primary means of spreading micropollutants, primarily because of their inadequate performance. However, efforts …

Mechanisms of competitive adsorption between trace organic contaminants and natural organic matter on activated carbon
… water treatment for removal of various organic micropollutants; nonetheless, the presence of natural organic matter (NOM) in source water can reduce its efficiency for micropollutant removal. NOM has been shown to compete with target contaminant via different mechanisms: direct competition for …

Photochemical processes in engineered aquatic systems for remediation of per- and polyfluoroalkyl substances and algae cultivation
… from engineered treatment processes (e.g., micropollutant removal) to natural biogeochemical processes (e.g., nutrient cycling). This thesis investigates (1) the application of a UV-sulfite photochemical treatment process for per- and polyfluoroalkyl substances (PFASs) destruction, and (2) …

Ammonia-monooxygenase-mediated cometabolic biotransformation and abiotic transformation of micropollutants
Biotransformation of a number of micropollutants (MPs) has been found to positively correlate with nitrification activities in inhibition studies of nitrifying activated sludge communities. To further elucidate roles played by ammonia-oxidizing bacteria (AOB), and nitrite-oxidizing bacteria (NOB) …

Treating filtered final effluent from the Cape Flats Wastewater treatment plant with ozone and biologically activated carbon filtration to remove pathogens and organic micropollutants
… source for human consumption given the organic micropollutants and pathogens it can contain. Hence, multi-barrier treatment trains and advanced processes are required. However, these are costly and therefore it is necessary to investigate how their cost can be optimized. Plumlee et al. (2014) …

ORGANIC MICROPOLLUTANTS ANALYSIS AND THEIR METROLOGICAL TRACEABILITY TO SI UNITS
… work concerned the determination of organic micropollutants in food matrices at trace level, with the aim of correctly evaluating the measurement uncertainty and establishing metrological traceability for the results of these measurements. The metrological traceability of organic …
