Reduction of Ice Thickness on Northern Water Reservoirs
Publisher: American Society of Civil Engineers
Abstract: Many northern communities rely on open reservoirs as a water source during winter. In the north, open reservoirs can experience ice thicknesses of over 2 m, which can result in a loss in usable storage of up to 60% of the ...
Measurement of Turbulent Flow in Standard Jar Test Apparatus
Publisher: American Society of Civil Engineers
Abstract: Although the jar test has long been used in coagulation and flocculation, there is little available information on vessel hydrodynamics. Vessel-average parameters such as the root-mean-square velocity gradient,
Microorganism Survival in Ice‐Covered Marine Environment
Publisher: American Society of Civil Engineers
Abstract: The concentration of microorganisms in the vicinity of a submerged marine outfall is governed by dilution and decay processes. Dilution is a physical process related to the hydraulic characteristics of the site. Decay of ...
Modeling of Dissolved Ozone Concentration Profiles in Bubble Columns
Publisher: American Society of Civil Engineers
Abstract: Mathematical models previously employed to analyze concentration profiles of dissolved ozone in bubble‐column contactors often assumed either plug flow or complete mixing. In this paper a more realistic model, the axial ...
Characterization of Mixing in Upflow Solids-Contacting Clarifier
Publisher: American Society of Civil Engineers
Abstract: It has been recognized that flocculation performance can be related to the mixing process. This process has traditionally been described by vessel average parameters such as the root-mean square velocity gradient
Optimization Study of Flocculation Mixing by Means of Grids
Publisher: American Society of Civil Engineers
Abstract: The purpose of this study was to optimize flocculation mixing created by single grids. Double and triple biplane grids were vertically oscillated within a standard 2 L jar. The turbulent velocities were measured using a ...
Turbulent Velocity in Flocculation by Means of Grids
Publisher: American Society of Civil Engineers
Abstract: Eleven types of single circular biplane grids with different diameter (
