Abstract: Arsenic-containing groundwater is used normally as drinking water after treatment in rural areas of some developing countries. This study describes removing arsenate [As(V)] by contact filtration on a sand media using ...

Abstract: Floc blankets are fluidized, concentrated beds of particles utilized in some upflow sedimentation tank reactor configurations in water treatment. The presence of a floc blanket can significantly enhance removal of turbidity ...

Abstract: Floc blankets are fluidized beds of aggregated suspended particles utilized in some upflow sedimentation tanks for drinking water treatment. Floc blankets can significantly enhance particle removal and may reduce operation ...

Abstract: Flocculation is a key step in treating drinking water for pathogen removal. Baffled hydraulic flocculators (BHFs) have many advantages, including plug-flow reactor kinetics, ease of construction, and operation without ...

Abstract: A differential-turbulence column (DTC) has been designed to simulate hydrodynamic and chemical processes associated with pollutant fate in aquatic environments. The reactor uses five vertically spaced oscillating grids to ...
