Wastewater Treatment Operator Training Manual is comprised of four chapters covering Wastewater Treatment Overview, Preliminary Treatment, Primary Treatment, and Natural Treatment Systems. Each chapter has specified learning objectives, detailed tables and figures, a five question quiz with answer sheet, and blank pages for note taking.

The four sections of this book go in to details about the following steps in the wastewater treatment process:

• Wastewater Treatment Overview provides information on the importance of wastewater treatment, the characteristics of wastewater and sources, elements of sampling programs, the fundamental elements of a conventional wastewater treatment system, and the role of an operator in treating wastewater.
• Preliminary Treatment explains the components and purpose of the preliminary treatment process at a typical wastewater treatment plant: septage receiving stations, screening, grinders, grit removal systems, flow management, and odor control.
• Primary Treatment covers the major concepts associated with primary treatment: components and performance efficiencies of primary clarifiers, considerations for sludge and scum removal, and key troubleshooting and maintenance of primary treatment processes.
• Natural Treatment Systems covers various types of natural treatment systems such as stabilization lagoons, infiltration systems, floating aquatic plant ponds, and constructed wetlands.
