Microbial consortia in full-scale pre-ozonated biologically active filters treating a high-DOC water: Effects of seasonal and operational variations Open
This study investigated the microbial dynamics in full-scale biologically active anthracite/silica sand (BAS) and granular activated carbon (BAC) filters used to treat high-DOC coagulated softened water. By analyzing these filter types acr…

Quantifying and characterizing major DOC fractions in water treatment processes: A simplified SPE method without recovering sorbed compounds Open
Practitioners often use specific UV 254 absorption (SUVA) as an indicator of hydrophobic (HPO) dissolved organic carbon (DOC) to evaluate removal efficiency and estimate trihalomethane formation potential (THMFP). However, current fraction…

Bioremediation of Chlorate and Chromium in Soil Columns Using Contaminated Site Native Culture Open
Chlorate and hexavalent chromium (chromate) are both widely used in different industries, and the improper waste management in the past left many sites with elevated concentrations in groundwater that pose potential risk to human and/or ec…

Bioremediation of Chlorate and Chromium Contamination with Native Microbial Culture in Cold Climate Open
Chlorate and hexavalent chromium are two chemicals with adverse health effects that may cause groundwater contamination in industrial areas. The objective of this study was to determine if the native microorganisms collected from a site co…

Filtrates and Sludge Generated in the Physicochemical Treatment of Wastewater from the Lead-Acid Batteries Production Open
Total lead (TPb) exists in Crude Wastewater (CW) from production of Lead-Acid Batteries (LABs) in water (WPb) and solid phase (SPb) as colloids and suspended solids. Sludges produced in chemical treatment of these wastewater were dewatered…

Preliminary investigation into the claims of the IBROM system Open
Membrane filtration is commonly applied to reduce dissolved organic carbon (DOC) to control the formation of trihalomethanes (THMs); however, high levels of DOC can cause severe fouling of reverse osmosis membranes. The integrated biologic…
Ozonation of natural organic matter and aquatic humic substances: the effects of ozone on the structural characteristics and subsequent trihalomethane formation potential Open
The effect of ozonation on the structural and chemical characteristics of natural organic matter (NOM) and its isolated humic fractions, humic acid (HA) and fulvic acid, were studied using Fourier transform infrared coupled to attenuated t…

Ion-exchange for trihalomethane control in potable water treatment – a municipal water treatment case study in Rainy River, Ontario, Canada Open
The objectives of this study were to investigate the ability for ion-exchange (IX) to control trihalomethane (THM) formation, and to act as a potential treatment addition (upgrade) to a conventional treatment plant in Rainy River Ontario, …

Membrane surface morphology and fouling in filtration of high DOC water Open
In Canada many potable water sources contain very high concentrations of Dissolved Organic Carbon (DOC), accompanied by a wide range of hardness. DOC reacts with chlorine used in water disinfection to form potentially carcinogenic chlorine…
