Course Description

278-Introduction to Wastewater Clarifier Design

This course introduces the reader to the key issues and considerations associated with successful and cost-effective design of primary and secondary clarifiers for wastewater treatment plants. The course presents an overview of the main advantages and disadvantages of rectangular and circular clarifiers and provides key design criteria for primary and secondary clarifiers.

In the course the reader will find guidance of how to select the most appropriate configuration, surface overflow rate, hydraulic detention time, and depth of primary and secondary clarifiers and how to tailor clarifier design to the typical challenges facing almost all wastewater treatment plants such as: excessive transient flows during wet weather conditions; septicity of the plant influent and primary sludge, occasional upsets of the activated sludge system resulting in poorly settling sludge; and episodes of rapid increase of sludge blanket depth, and deterioration of clarifier effluent quality.

The course discusses how the configuration and type of the selected plant influent pump station, screening and grit removal equipment impact clarifier performance as well as how clarifier operation influences other key wastewater treatment plant facilities such as the activated sludge aeration basins, sludge thickeners, and aerobic and anaerobic digesters. The reader will learn about the typical approaches used for optimization of the clarifier — activated sludge system design and will find case studies implementing such approaches at full-scale wastewater treatment plants.

The course was suitable for a novice in the field, yet contained enough detail to be challenging.
