Journal ArticleDOI
Behaviour and fate of perfluoroalkyl and polyfluoroalkyl substances (PFASs) in drinking water treatment: a review
TL;DR: Early observations suggest that activated carbon adsorption, ion exchange, and high pressure membrane filtration may be effective in controlling these contaminants, however, branched isomers and the increasingly used shorter chain PFAS replacement products may be problematic as it pertains to the accurate assessment of PFAS behaviour through drinking water treatment processes.
Journal ArticleDOI
Adsorption characteristics of selected pharmaceuticals and an endocrine disrupting compound—Naproxen, carbamazepine and nonylphenol—on activated carbon
TL;DR: Comparison of isotherms for the target compounds to those for other conventional micropollutants suggested that naproxen and carbamazepine could be effectively removed by applying the same dosage utilized to remove odorous compounds at very low concentrations.
Journal ArticleDOI
Modification of poly(vinylidene fluoride) ultrafiltration membranes with poly(vinyl alcohol) for fouling control in drinking water treatment.
TL;DR: The improved fouling resistance of the modified membrane was related to the membrane physiochemical properties, which were confirmed by pure water permeation, X-ray photoelectron spectroscopy, and contact angle, zeta potential and roughness measurements.
Journal ArticleDOI
Identifying fouling events in a membrane-based drinking water treatment process using principal component analysis of fluorescence excitation-emission matrices.
Ramila H. Peiris,Cynthia Hallé,Hector Budman,Christine Moresoli,Sigrid Peldszus,Peter M. Huck,Raymond L. Legge +6 more
TL;DR: The fluorescence EEM-based PCA approach presented here is sensitive enough to be used at low organic carbon levels and has potential as an early detection method to identify high fouling events, allowing appropriate operational countermeasures to be taken.
Journal ArticleDOI
Assessing the Performance of Biological Filtration As Pretreatment to Low Pressure Membranes for Drinking Water
TL;DR: Biopolymer removal was influenced by contact time and temperature, and the biofilter with the longer contact time led to greater reductions in both hydraulically reversible and irreversible fouling.
