An Introduction to Secondary Wastewater Treatment

Course Description:
Wastewater treatment is usually characterized as consisting of four sequential processes: preliminary, primary, secondary and tertiary treatment.  This course will introduce you to processes and equipment for secondary treatment of wastewater.  You will be introduced to descriptions, functions and design considerations for trickling filter plants, activated sludge plants, and wastewater treatment ponds.  You will be introduced to special considerations for wastewater treatment plants in hot and cold climates.  You will learn how the secondary treatment processes work together with the preliminary, primary, tertiary and sludge handling processes to form a complete wastewater treatment plant.

Course Outline:
1. General considerations
2. Trickling filter plants
3. Activated sludge plants
4. Wastewater treatment ponds
5. Sewage treatment in hot climates
6. Special considerations for cold climates
7. References

Learning Objectives:
At the conclusion of this course, the student will be able to:

• Outline the design basis and criteria for trickling filter plants.
• Describe the different dosing intervals for different classifications of trickling filters.
