I am working on a thesis with the topic "Cost effective ways to increase plant capacity". The plant I am working on is a standard activated sludge process.
Anyways my idea is to upgrade the existing secondary clarifiers with plate settlers. They increase the settling surface and therefore should help the problem. Otherwise I am afraid that they will clog because of the sludge volume. Do you have any experience with plate settlers in a municipal WWTP? I found this video which gave me the idea: https://youtu.be/wyz49PewhVk
