Скачать или смотреть How Secondary Clarifiers Work: RAS, WAS, and Sludge Age Explained

The secondary clarifier is a critical component in wastewater treatment processes, ensuring effective solid-liquid separation after biological treatment.

In this video, we explain:
• The role of the secondary clarifier in Effluent Treatment Plants (ETPs) and Sewage Treatment Plants (STPs)
• How Return Activated Sludge (RAS) and Waste Activated Sludge (WAS) function
• The importance of controlling sludge age (Solids Retention Time) for process stability and compliance
• Common operational challenges such as bulking sludge, foaming, and turbid discharge

This video is created for plant operators, environmental engineers, and professionals involved in wastewater treatment and process optimization.
