Biofilm Dynamics in Drinking Water Biofiltration & Downstream Nanofiltration Biofouling
(University of Waterloo, 2018-05-17)Natural organic matter (NOM) is a concern in many surface waters and must be removed by water treatment processes for cost-effective production of safe and aesthetically pleasing drinking water. Biological filtration is ... -
Biofiltration in Drinking Water Treatment: Reduction of Membrane Fouling and Biodegradation of Organic Trace Contaminants
(University of Waterloo, 2010-02-17)The goal of drinking water treatment is to produce and deliver safe water to the consumers. To achieve these objectives water treatment plants are designed based on the concept of the multibarrier approach which combines ... -
Biologically Active Filtration Media Properties: Practical and Mechanistic Implications
(University of Waterloo, 2017-01-16)Biologically active filtration [BAF] can be used to concurrently remove particles and natural organic matter during drinking water treatment. The selection of a given media type for use in BAF can impact filter performance, ... -
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 and Nutrient (Phosphorus) Enhancement for Polymeric Ultrafiltration Membrane Fouling Control
(University of Waterloo, 2013-12-10)Membrane filtration is growing in popularity as a viable technology for drinking water treatment to meet high demand and regulatory requirements. While many improvements have been made to the technology in the past decade, ... -
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. ... -
Initial Biodegradation Potential of Microcystin-LR by Biofilters Experiencing Sudden Cyanobacterial Blooms in Drinking Water Treatment
(University of Waterloo, 2018-09-20)Cyanobacterial blooms have become a major cause of drinking water problems because certain metabolites from cyanobacteria are toxic to human health. Microcystin-LR (MC-LR) is one of the most commonly detected cyanotoxins. ... -
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) ... -
Pre-Treatment Evaluation Prior to Ultrafiltration in Secondary Effluent Treatment for Water Reuse
(University of Waterloo, 2015-12-17)Reusing wastewater can assist in solving water shortage problems, reduce the amount of wastewater discharged to surface water bodies and, by extension, alleviate its adverse effects on humans and the environment. Organics ...
