aeration-foam - Question and answers

I've been dealing with persistent foam in the aeration tank at our wastewater treatment plant, which is reducing settling efficiency in the clarifier. What steps can I take to diagnose and resolve this issue?

Waste Water Treatment troubleshooting aeration-foam

Our plant uses an activated sludge system for municipal wastewater. I've monitored parameters like mixed liquor suspended solids (MLSS) and dissolved oxygen, which are within normal ranges. The foam is thick and white, and I suspect it might be linked to recent changes in industrial discharges. I've tried adjusting the aeration rates but with limited success. Any advice on systematic troubleshooting would be helpful.
