Large seasonal variations in microbial drinking water quality can occur distribution networks, but are often not taken into account when evaluating results from short-term sampling campaigns. Temporal dynamics bacterial community characteristics were investigated during a two-year monitoring campaign full-scale system operating without detectable disinfectant residual. A total of 368 samples collected on biweekly basis at the treatment plant (WTP) effluent and one fixed location network...
A systematic approach is presented for the assessment of (i) bacterial growth-controlling factors in drinking water and (ii) impact distribution conditions on extent growth full-scale systems. The combines quantification changes autochthonous cell concentrations systems with laboratory-scale batch potential tests samples under defined conditions. were done by direct incubation samples, without modification original flora, flow cytometric growth. This method was shown to be reproducible (ca....
Biocides may be used to control biofouling in spiral-wound reverse osmosis (RO) and nanofiltration (NF) systems.The objective of this study was investigate the effect biocide 2,2-dibromo-3-nitrilopropionamide (DBNPA) dosage on control.Preventive studied applying a continuous substrate (0.5 mg/L) DBNPA (1 mg/L).Curative pre-grown biofilms, once again mg acetate C/L) 20 mg/L).Biofouling studies were performed membrane fouling simulators (MFSs) supplied with biodegradable DBNPA.The pressure...
Spatial and short-term temporal changes in water quality as a result of age fluctuating hydraulic conditions were investigated drinking distribution system. Online measurements total intracellular adenosine tri-phosphate (ATP), intact cell concentrations measured with flow cytometry (FCM), turbidity, particle counts performed over five weeks at subsequent locations the The high number parallel FCM ATP revealed combined effect final disinfection on spatial microbiology results underlined that...
Sediment formation in drinking water distribution systems can lead to brown at customer taps. Previous studies have shown that sediment is closely linked with (micro)biological processes the system, however mechanism not fully understood. Most available on discoloration or are based modeling, pilot-scale experiments, low frequency data collected during pipe flushing. In this study, long-term development a large-scale system was studied one location over 11 years and several locations along...
High drinking water temperatures occur due to climate change and could enhance the growth of opportunistic pathogens in systems. We investigated influence on Pseudomonas aeruginosa, Stenotrophomonas maltophilia, Mycobacterium kansasii Aspergillus fumigatus biofilms with an autochthonous microflora. Our results reveal that P. aeruginosa S. maltophilia biofilm already occurred at 15.0 °C, whereas M. A. were able grow when above 20.0 °C 25.0 respectively. Moreover, maximum yield increased...
Abstract Drinking water utilities currently rely on a range of microbiological detection techniques to evaluate the quality their drinking (DW). However, microbiota profiling using culture-free 16S rRNA gene next-generation sequencing (NGS) provides an opportunity for improved monitoring microbial ecology and DW. Here, we evaluated utility previously validated platform (MYcrobiota) investigate dynamics full-scale, non-chlorinated DW distribution system (DWDS). In contrast conventional...
