2. Surface Water Treatment, Part 1 Objectives

Following completion of Video 2 and Chapter 2, students should be able to:

  1. Identify safety hazards encountered by the operators of small water systems.
  2. Safely perform the tasks essential for the operation and maintenance of small surface water treatment facilities.
  3. Describe those aspects of Worker Right-To-Know laws that apply to small water system O&M.
  4. Recognize threats of contamination to water supply sources.
  5. Outline the procedures of a sanitary survey.
  6. Explain why operators must take necessary precautions to produce water free from disease-producing organisms.
  7. Describe why turbidity is measured and monitored.
  8. Perform a jar test and apply the results.
  9. Operate, maintain, and troubleshoot surface water treatment processes for:
    1. Coagulation
    2. Flocculation
    3. Sedimentation (settling)
    4. Filtration (including slow sand filtration)

NOTE: Chapter (Video) 3 will cover material on how to safely operate, maintain, and troubleshoot surface water treatment processes for corrosion control, disinfection, and also taste and odor control. Chapter 3 also will explain how to operate all of these processes in conventional water treatment plants, package plants, and slow sand filter plants. Material will be provided on how to develop and implement a preventive maintenance program for small water systems.
