Course Description: This four-day course is directed to Grade I or II certified wastewater treatment plant operators planning to take the State of California’s Grade III Wastewater Operator Certification Exam. The following treatment processes will be reviewed: anaerobic digestion, solids thickening and dewatering, pumping, chemical dosing, trickling filters, and the activated sludge process and its modifications. In addition, certain miscellaneous topics such as the BOD test, nitrification/ denitrification, disinfection, and others will be discussed. Wastewater math applicable to the Grade III certification exams will also be reviewed and students will have the opportunity to practice solving the kinds of problems that might appear on the Grade III exams. The need to study the material cannot be overemphasized.
