Abstract: The Salt River Pima-Maricopa Indian Community (SRPMIC) of Maricopa County, Arizona, has determined that it needs to further the economic and social welfare of the community. The community has further determined that these ...

Abstract: The purpose of this paper is to show the current limits on Chinese construction-management practice. In an era of increased global competitiveness, which extends to the construction industry, China is fighting an uphill, ...

Abstract: The flow, sediment transport, and bathymetry at equilibrium conditions in loose-bed open channels are predicted using a fully three-dimensional (3D) Reynolds-Averaged Navier-Stokes model that was validated for cases in ...

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: Most constructors intuitively understand that there is a relationship between payload weight and haul unit performance. At the same time, project managers constantly push the limits of rated truck payload as they seek ...
