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: While successful in removing turbidity and pathogens from drinking water, slow sand filters require ripening periods at the beginning of each filter run. The premise of this research was that it should be possible to enhance ...

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

Abstract: The postsedimentation addition of polyaluminum chloride (PACl) was investigated as a means to enhance particle removal efficiency in dual media filtration. The process modification was evaluated in laboratory studies and ...

Abstract: Infrastructure for water treatment faces numerous challenges around the world, including the high failure rate of digital, electronic, pneumatic, and mechanical control systems due to their large number of components and ...

Abstract: Rapid sand filters are a familiar and mature technology, but the mechanical sophistication they incorporate in industrialized nations limits their sustainable application in developing countries. Conventional rapid sand ...
