Categories of residual solids management processes contained in this chapter include thickening, stabilization, conditioning, dewatering, volume reduction, and land disposal. Following completion of Chapter 3, with regard to the processes in these solids handling and disposal categories, students should be able to:

1. Explain the purposes of the processes.
2. Properly start up, operate, shut down, and maintain these processes.
3. Develop operating procedures and strategies for both normal and abnormal operating conditions.
4. Identify potential safety hazards and conduct their duties using safe procedures.
5. Troubleshoot when a process does not function properly.
6. Review plans and specifications for the processes.

The purpose of Chapter 3 is to teach students about several of the most widely used methods for handling and disposing of wastewater treatment residual materials. The chapter teaches students how to operate thickening, stabilization, conditioning, dewatering, and volume reduction processes. It also describes methods for disposing of both liquid and solid industrial waste residuals and discusses the regulations that govern disposal of the wastes.
