Primary Treatment at Wastewater Treatment Plants is a volume in the Operator's Guide Series and focuses on that segment of conventional wastewater treatment known as primary treatment. The author has developed the general operational procedures described in the book from his own experience as a plant operator, superintendent, and operations consultant. These procedures should reinforce your understanding of the standard operations at your plant and may even spark new ideas that could prove beneficial to overall operations. For this reason, blank pages are provided at the end of each chapter so that notes and ideas can easily be added to this handy volume.
Topics addressed in the book include a discussion of the primary treatment process, equipment, start-up and shutdown procedures, routine operator duties, emergency response procedures, general safety rules, and good housekeeping and odor control tips. The book also contains a section featuring a variety of troubleshooting hints designed to help you run a smooth operation. These techniques will prove useful in identifying problems, and the procedures discussed will help you get the operation up and running again.
