Water Treatment Operation Volume 1 & Volume 2

Water Treatment Operation Volume 1 & Volume 2

Two books that have both been read a lot and made me ready to pass my water supply exams . They are highlighted and underlined in which could help you study to know key points . The binding on the grade 2 book must have had a poor glue job from factory so a few pages are coming apart from it but all of there for you to study .
