WCW24

Wet weather conditions can bring about challenging conditions for operators of municipal wastewater treatment facilities, especially those facilities that operate with a combined sewer system. Extreme wet weather conditions can bring about flows that exceed the hydraulic capacity of the mainstream treatment process, leading to bypass events that channel the excess water away from the mainstream treatment process. Although dilute, the bypassed water can still carry harmful contaminants that should be reduced prior to discharge. In this presentation, we will review pile cloth filter configurations for wet weather and primary wastewater treatment. Full-scale designs and pilot-scale results will be showcased to demonstrate the technology for these wet weather conditions at municipal wastewater treatment facilities.
