Water and Wastewater Technology

This is an excellent book to read if you want to learn about wastewater treatment or just if you want to refresh your knowledge of this theme. The book presents easy to follow examples in many of the topics, say, clarifiers design (primary, intermediate, final), Aeration basins, etc. I prefer this book rather than Viessman & Hammer because it is much more friendly. I have not check yet the part of the book corresponding to water treatment, but the wastewater part is very good.
