Development of Advanced Characterization Techniques for Organic and Colloidal Material of Relevance to Ultrafiltration Membranes in Drinking Water Treatment
(University of Waterloo, 2016-01-15)Ultrafiltration (UF) membranes, which can effectively remove colloidal/particulate matter (C/P), macromolecules, and pathogenic microorganisms, have gained increasing acceptance in the drinking water industry. However, ... -
Direct Biofiltration as a Pretreatment to Control Fouling in Ceramic Membranes in Drinking Water Treatment
(University of Waterloo, 2016-09-27)Ceramic membranes have been widely and successfully used in the food and beverage processing industry. Despite their success, ceramic membranes are not commonly employed in drinking water treatment due to their high initial ... -
Drinking Water Softening/Scale Prevention Technology Assessment and Performance of Template Assisted Crystallization
(University of Waterloo, 2019-06-18)Hard water typically has a hardness concentration over 120 mg/L CaCO3. Hardness is not a regulated drinking water parameter and does not have severe health effects. However, hard water causes more soap and detergent ... -
Granular Activated Carbon for the Removal of Seasonally Present Microcystin-LR
(University of Waterloo, 2017-04-20)Microcystin-LR (MC-LR) is a potent hepatotoxin, produced by cyanobacteria. MC-LR is the most commonly regulated cyanotoxin. MC-LR typically occurs seasonally in late summer in temperate regions, such as the North American ... -
Impact of Operational and Design Parameters on Natural Organic Matter Removal and its Correlation with NDMA Precursor Removal or Formation during Biofiltration in Drinking Water Treatment
(University of Waterloo, 2019-05-21)NOM is a complex mixture of organic compounds that are present in all natural waters and is mainly originating from plant and aquatic organism degradation products. Therefore, the specific composition of NOM is site-specific. ... -
Investigating the Role of Water Quality on the Galvanic Corrosion of Lead in Hard Drinking Water with a Focus on NOM
(University of Waterloo, 2020-05-25)Although the use of lead in water distribution systems is currently prohibited in Canada, old lead service lines, lead solder, and lead containing plumbing fixtures continue to be sources of lead in the tap water of many ... -
Micro- and Nanoplastics Removal through Drinking Water Treatment Processes: Insights from Published Investigations and Development of a Possible Regulatory Approach
(University of Waterloo, 2023-08-02)Micro- and nanoplastics (MNPs) have emerged as significant environmental pollutants with potential implications for human health. The presence of MNPs in freshwater bodies, such as lakes, rivers, and sometimes groundwater, ... -
Operational Robustness of Drinking Water Treatment Plants with Respect to Turbidity Representing Normal, Severe and Unprecedented Weather Events
(University of Waterloo, 2022-06-16)Drinking water treatment plants (DWTPs) are required to supply safe drinking water continuously to the consumers to protect public health and sanitation. The adverse effects of climate change can influence raw water quality, ... -
Performance of Biological Filters for Drinking Water Treatment and Their Use for High Pressure Membrane Biofouling Control
(University of Waterloo, 2016-01-18)Biofiltration is a promising green drinking water treatment technology that can reduce the concentration of biodegradable organic matter (BOM) in water. Direct biofiltration or biofiltration without pretreatment (BFwp) ... -
Predicting the Removal of Micropollutants in Lake Ontario and Grand River using Ozonation
(University of Waterloo, 2019-01-15)Micropollutants occur at low concentrations (µg/L to ng/L), can have a range of environmental and health effects, and can enter surface water through run-off from fields and wastewater discharge. Surface water is used for ... -
Removal of Perfluorinated Compounds in Drinking Water Treatment: A Study of Ion Exchange Resins and Magnetic Nanoparticles
(University of Waterloo, 2017-11-21)Perfluorinated compounds (PFCs) are emerging contaminants which have been detected in various environmental compartments, including drinking water sources. Because of their potential risks to human health, PFCs in drinking ... -
Super-fine Powdered Activated Carbon for the Removal of Microcystin-LR from Drinking Water
(University of Waterloo, 2021-11-24)Harmful algal blooms are considered threats to drinking water quality. During drinking water treatment, suspended and dissolved materials must be removed and treated, and in the case of cyanobacteria, these are intact cells ... -
Treatment of the Cyanotoxins Cylindrospermopsin, Microcystin-LR, and Anatoxin-a by Activated Carbon in Drinking Water
(University of Waterloo, 2017-08-23)Cyanotoxins are known to cause human and animal illness, in some cases resulting in death, and their presence in drinking water is a potential risk to public health. Cylindrospermopsin (CYL), microcystin-LR (MC-LR), and ...
