Part of: Critical Issues in Water and Wastewater Treatment


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 the unit is thought to be a major factor, the internal details are the most important design factors in determining a clarifier's capacity. The ability to analyze the impact of these details, along with the operational and maintenance practices, is critical to the evaluation of its performance. The final challenge is how to most effectively modify a clarifier's hydraulic characteristics in order to optimize its performance.
