Abstract: The relative dissolution rates of several commercial hydrated limes were evaluated. Significant differences in dissolution rates were observed ranging from a time of <10 s for 90% dissolution to 1 min for a 5% slurry. A ...

Abstract: Multiparameter monitors (sondes) were installed at four sites in a stream in the Great Smoky Mountains National Park. These sondes recorded pH, turbidity, and other parameters every

Abstract: Fluidized bed crystallizers (FBCs), also called pelletizers or pellet reactors, are an attractive alternative to conventional water softening. FBCs produce a coarse, spherically grained, easily dewatered, calcitic sand as ...

Abstract: A method for using a modified jar test in conjunction with a hydraulic similitude calculation was developed to predict sedimentation basin performance. The method was tested at the Mark B. Whitaker Water Treatment Plant ...

Abstract: For small communities, iron removal from groundwater by conventional methods is sometimes cost prohibitive. An experimental investigation was conducted to determine the effectiveness of sequestering this iron by polyphosphate ...

Abstract: A dynamic computer model of a pump station at a wastewater-treatment plant was developed. The model predicts pumping rates and wet well levels as a function of time. The pumps included both constant- and variable-speed ...

Abstract: Few case studies are available on stream water quality monitoring during road construction, especially in highly protected watersheds. Recent reconstruction of two tunnels and approach roads in the Great Smoky Mountains ...

Abstract: Missing data commonly exist in operational records of wastewater treatment plants, such as influent and effluent water quality data. To deal with missing data, time series models that characterize trend, lag, and seasonality ...
