Impact of carbon-based nutrient enhancement on biofiltration performance for drinking water treatment

Autor: Liz Taylor-Edmonds, Robert C. Andrews, Yu Zhao

Publikováno v: Journal of Environmental Sciences. 82:124-131

Incorporation of a carbon-based nutrient enhancement strategy for drinking water biofiltration is an attractive option, especially for source waters which contain recalcitrant organics. This study compared biofilters that were operated in parallel an

Publikováno v: Water Research. 155:403-409

Biofiltration has been shown to be effective for disinfection by-product (DBP) precursor control, however few studies have considered its role in the potential formation of DBPs. Biofilm is composed of heterogeneous bacteria as well as extracellular

Pilot-scale comparison of cyclically and continuously operated drinking water biofilters: Evaluation of biomass, biological activity and treated water quality

Autor: Corinne Bertoia, Robert C. Andrews, Michael J. McKie, Susan A. Andrews, Liz Taylor-Edmonds

Publikováno v: Water Research. 149:488-495

The objective of this pilot study was to evaluate the impact of cyclical (operated 8–12 h per day) and continuous biofilter operation with respect to biomass development, biological enzyme activity and treated water quality (in terms of organics, n

Quantitative microbial risk assessments for drinking water facilities: evaluation of a range of treatment strategies

Autor: Robert C. Andrews, Joshua G. Elliott, Liz Taylor-Edmonds

Publikováno v: Environmental Science: Water Research & Technology. 5:1943-1955

Quantitative microbial risk assessments (QMRA) was conducted for 10 drinking water facilities located in Canada. Monthly risk estimates were based upon a suite of reference pathogens for the raw water, as well as detailed process assessments that con

Evaluation of enzyme activity for monitoring biofiltration performance in drinking water treatment

Autor: Meaghan R. Keon, Michael J. McKie, Robert C. Andrews, Liz Taylor-Edmonds

Publikováno v: Water research. 205

Many water providers monitor adenosine triphosphate (ATP) as an indicator of biological acclimation of their biofilters; however, strong correlations between ATP concentration and filter performance (e.g., organic matter or disinfection by-product pr

Impact of biofilter operation on microbial community structure and performance

Autor: Robert C. Andrews, Vivek A. Nemani, Michael J. McKie, Liz Taylor-Edmonds

Publikováno v: Journal of Water Process Engineering. 24:35-41

The objectives of this pilot-scale study were to evaluate biological acclimation of virgin granular activated carbon (GAC), quantify the impact of nutrient (phosphorus and nitrogen) enhancement and to compare the performance of parallel biologically

Low toxicological impact of wastewaters on drinking water sources

Autor: Nicole Zollbrecht, Robert C. Andrews, Shelir Ebrahimi, Liz Taylor-Edmonds, Mustafa Iqbal

Publikováno v: Water research. 171

Surface waters may contain varying levels of wastewater effluent associated with de facto reuse, which may influence their toxicological properties both prior to and following treatment. This study examined the genotoxic response of three surface wat

Certain unregulated disinfection byproducts (DBPs) are more of a health concern than regulated DBPs. Brominated species are typically more cytotoxic and genotoxic than their chlorinated analogs. The impact of granular activated carbon (GAC) on contro
