Design of Clarifiers and Sedimentation Basins Using an Advanced Numerical Modeling Approach
Design Evolution for Stacked Clarifiers
Use of NaOH to Control pH for Solubilization of Waste Activated Sludge
Waste activated sludge was collected from the final clarifier of a local municipal wastewater treatment plant. NaOH was used in comparison made of the controlled pH batch experiments with...
Implementation of Dissolved Air Flotation Technology
Application of Numerical Models in the Design of Clarifiers
In this study, a numerical model of a circular clarifier was applied to reveal the effects of the water depth on the hydraulic and removal efficiency. The velocity and solids concentration...
Clarifier Enhancements Yield Excellent Performance
The critical role of final clarifiers in meeting effluent permit requirements in indisputable. Poor performance of the final clarification step may adversely affect effluent quality. Experience...
Optimizing Secondary Clarifier Performance: A Presentation Outline
Optimizing secondary clarifier performance is an activity that involves a consideration of the design, the maintenance, and the operation of the clarifier. Although the basic shape of...
Evaluating Activated Sludge Secondary Clarifier Performance: A Protocol
To establish a consistent methodology for evaluating secondary clarifier performance, the ASCE Clarifier Research Technical Committee prepared procedural guidelines in the form of a draft...
Sludge Hopper Design for Activated Sludge Clarifiers
Only in the past few years has any attention been allocated to the transport characteristics of sludge collectors. However, no attention has been given to a design rationale for the sludge...
