The Water Online Show: Aqua-Aerobic Systems, Inc.

Activated sludge has been around for decades, but newer approaches aim to change the sludge itself. The distinction between densified and granular sludge comes down to size and how much of the biomass reaches it, and that difference has real consequences for settling, simultaneous nitrification and denitrification, and biological phosphorus removal. In this Water Online Show on Location conversation, host Angela Godwin speaks with Brett Quimby and Manuel de los Santos of Aqua-Aerobic Systems about where batch and flow-through configurations diverge, which applications favor one approach over the other, and what implementation looks like for retrofits versus greenfield builds.

Watch to see how the two technologies compare in practice.
