srt or dynamic sludge age
SRT or Dynamic Sludge Age?

Jon Bolmstedt Master thesis Lund, November 2000

Robert Lagrange

dynamic sludge age or srt
Dynamic Sludge Age or SRT?

Based on the equation the sludge age changes as soon as

the flow of waste activated sludge changes.

Not quite true

pH will really change only when there is a big upset
