This is the first volume in a series of practical "operator-oriented" books written to help ensure the proper operation and maintenance of water and wastewater plants. The guides concentrate on how to perform the actual work required to keep a plant running smoothly. They are not detailed, reference-filled treatment studies.
Basic Mechanical Maintenance Procedures at Water and Wastewater Plants is written in a straightforward manner using everyday language. It will show you how to keep systems running smoothly, troubleshoot and solve problems, reduce equipment failure, practice safety, and save money. Each chapter is written in an easy-to-follow, step-by-step format, with extra pages and room for notes so you can customize the book to meet your specific needs. The book includes information on the following:
Equipment lockout procedures
Shafts and couplings
Mechanical power transmission
This book is a "must have" for all water and wastewater operations and maintenance personnel.
