Riverbank filtration for control of microorganisms: results from field monitoring.
Microbial monitoring was conducted over a period of more than 1 year at three full-scale riverbank filtration (RBF) facilities, located in the United States along the Ohio, Missouri, and Wabash Rivers. Results of this study demonstrated the potential for RBF to provide substantial reductions in microorganism concentrations relative to the raw water sources. Cryptosporidium and Giardia were dete...
متن کاملRiverbed Clogging and Sustainability of Riverbank Filtration
Clogging refers to a reduction of riverbed hydraulic conductivity. Due to difficulties in determining the thickness of the clogging layer, the leakage coefficient (L) is introduced and used to quantify the recoverable portion of bank filtrate. L was determined at several riverbank filtration (RBF) sites in field tests and using an analytical solution. Results were compared with data from simila...
متن کاملHydraulic aspects of riverbank filtration—field studies
The Düsseldorf waterworks have been using riverbank filtration since 1870 with bank filtration as the most important source for public water supply in this densely populated and industrialised region. There have been many threats to this supply in the last few decades—e.g. poor river water quality, heavy clogging of the riverbed, accidental pollution—which had to be overcome. First field studie...
متن کاملImpacts of extreme flooding on riverbank filtration water quality.
Riverbank filtration schemes form a significant component of public water treatment processes on a global level. Understanding the resilience and water quality recovery of these systems following severe flooding is critical for effective water resources management under potential future climate change. This paper assesses the impact of floodplain inundation on the water quality of a shallow aqu...
متن کاملRiverbank filtration potential of pharmaceuticals in a wastewater-impacted stream.
Pharmaceutical contamination of shallow groundwater is a substantial concern in effluent-dominated streams, due to high aqueous mobility, designed bioactivity, and effluent-driven hydraulic gradients. In October and December 2012, effluent contributed approximately 99% and 71%, respectively, to downstream flow in Fourmile Creek, Iowa, USA. Strong hydrologic connectivity was observed between sur...
