Applicability Assessment of Subcritical Flux Operation in Crossflow Microfiltration with a Concentration Polarization Model
Publisher: American Society of Civil Engineers
Abstract: In the process of crossflow microfiltration, a deposit of cake layer tends to form on the membrane, which usually controls the performance of filtration. However it is found that there exists a condition under which no ...
Effective Diameter for Shear-Induced Diffusion for Characterizing Cake Formation in Crossflow Microfiltration at Polydisperse Conditions
Publisher: American Society of Civil Engineers
Abstract: During crossflow microfiltration, formation of cake layer on the membrane inhibits the filter performance. Previous studies on cake formation have focused on the monodisperse conditions, although most field applications ...
Closure to “<i>Redundancy‐Constrained Minimum‐Cost Design of Water‐Distribution Nets</i>” by Heekyung Park and Jon C. Liebman (January/February, 1993, Vol. 119, No.1)

Redundancy‐Constrained Minimum‐Cost Design of Water‐Distribution Nets
Publisher: American Society of Civil Engineers
Abstract: Quantification of the amount of redundancy in a looped water‐distribution network is necessary in order to compare different designs and to use an optimization approach in the design of the system. In this work, redundancy ...
Uncertainty Analysis of Mound Monitoring for Recharged Water from Surface Spreading Basins
Publisher: American Society of Civil Engineers
Abstract: This study has conceptually reviewed issues related to implementation of a groundwater mound monitoring well (GMMW) for monitoring recharged water from a surface spreading basin with emphasis on uncertain hydrogeological ...
Reaggregation of Flocs in Coagulation-Cross-Flow Microfiltration
Publisher: American Society of Civil Engineers
Abstract: Cake layer in cross-flow microfiltration can be reduced by coagulation of particles. This is because enlarging particle size by coagulation increases shear induced diffusivity and the back transport of rejected particles. ...
Effects of Bubble Size and Diffusing Area on Destratification Efficiency in Bubble Plumes of Two-Layer Stratification
Publisher: American Society of Civil Engineers
Abstract: Effects of bubble size, bubble diffusing area, and other parameters in air diffusers on destratification are studied using laboratory- and pilot-scale tanks with two layers. Dimensionless group involving such variable as ...
