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: Mechanistically based scalable algorithms for design and operation of hydraulic flocculators were developed in this research based on observations of residual turbidity for a range of influent turbidities (5–500 NTU) and ...

Abstract: Accurate chemical dosing in water treatment plants is imperative to ensure optimal efficiency of flocculation and disinfection. Design algorithms, calibration techniques, and standardized components are presented for a ...

Abstract: Fluidized-bed pretreatment of a rapid sand filter with alum [

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: Settling and entrainment are the dominant processes governing noncohesive particle concentration throughout the water column of salt-wedge estuaries. Determination of the relative contribution of these transport processes ...

Abstract: In the operation of porous media filtration systems, poor initial performance is often observed, in which particle removal is less than desired. Alum (

Abstract: In this study, precipitation of
