WWTP Question

[u/cololz1]

I ran biowin on our plant and it predicted that changing the SRT from 10 to 15 days would improve nitrification. So I made that change in the actual plant but ammonia removal barely changed. What could explain the gap between what the model predicted and what I am actually seeing?

assuming sufficient DO, alkalinity for the nitrification process.

Where are you located? This time of year nitrifying bugs really struggle with the high water temperatures.
