Methods for Assessing Wastewater Lagoon Performance
EBS, recently presented at the 2019 AL/MS Water Jam on “Methods for Assessing Wastewater Lagoon Performance.” The presentation addressed ways to identify and troubleshoot issues that may arise in your wastewater treatment system.
Troubleshooting Aerated Stabilization Basin
Aerated Stabilization Basin (ASBs) performance can be associated with numerous root causes, both chronic and intermittent. The three main conditions leading to loss of system performance and potential permit violations are discussed below. Temporary upsets due to...

Concern or Curiosity? Part 2 - Thiothrix and Type 021N Mike Foster, Principal Consultant - Environmental Business Specialists, LLCPaul Klopping, Principal Consultant - Callan & Brooks In part one of this series, we discussed the differences between activated...
Filamentous Bacteria in Aerated Stabilization Basins: Part 1
Filamentous bulking has long been the bane of activated sludge operations. Biomass or sludge bulking is generally defined as mixed liquor with a Settled Volume Index (SVI) of >150 ml/g. However, sludge bulking does not definitively translate to a sludge bulking...
Pros and Cons of Aerated Stabilization Basins and Activated Sludge Systems
In North America, there are predominantly two systems used to biologically treat industrial wastewater: the aerated stabilization basin (ASB or aerated lagoon) and the activated sludge system. These two systems have far more similarities than differences. Both pro...
