Basically exactly what you’re expecting, I think a separate chapter explaining common treatment plant workflows would be helpful instead of being buried in different chapters. But overall not a snoozefest and definitely helped me study for my T1 test. Definitely better than the AWWA water distribution book but that’s my personal preference.

This is the worst edited textbook I have ever read. Get the Sacramento State book instead. The editing is to the point where information is wrong. Don’t bother with the questions because whoever wrote them didn’t read or understand the chapters. The answers in the back of the book are obviously for different questions.
