Better Together Combined Activated Sludge and Trickling Filter Processes

Did you know that trickling filters can be integrated into activated sludge processes? In this session, we review the design philosophy behind this pairing, and explore methodologies of trickling filter-solids contact, roughing filter-activated sludge, and activated sludge-nitrifying trickling filter processes. John Harrison P.E., Consulting Engineer and owner of John R Harrison Consulting, will be leading this session.
