What You'll Learn
- Explain why particles stay suspended, what coagulants do, and how jar tests guide a coagulant dose.
- Describe flocculation, sedimentation basin flow paths, sludge blankets, and how to respond to a settling upset.
- Run filters as a barrier: ripening, filter-to-waste, head loss, turbidity breakthrough, rate changes and run length.
- Describe the backwash sequence, bed expansion and air scour, and spot mudballs, cracks and media loss.
- Explain membrane barriers, integrity testing, fouling and scaling, cleaning, and cartridge and bag filters.
- Apply disinfection practice: chlorine forms, demand and residual, contact time and CT, chloramines and UV.
- Control water chemistry: pH and alkalinity, corrosion control, orthophosphate, iron and manganese, taste and odor.
- Manage residuals and plant water: backwash water recovery, sludge thickening, dewatering and drying beds.

Where Does This Course Count?
A course counts toward your continuing education credit only once your state or province accepts it. Today our courses count in Alabama, Arizona, Idaho, South Carolina, where courses need no pre-approval, and we are asking more states. Ask us to add your state or province.
Do I Need an Account?
Yes, to take the course. Signing in lets us record your time and issue your certificate. This page, the topic pages and the practice questions need no account.
Can I Skip Ahead?
No. Each page has a minimum time before the next one opens, and your time is recorded.
What Do I Get When I Finish?
A certificate of completion from Operator Master for 1.0 hour, once you pass the final with 80% or better. Your operator certificate or license always comes from your state, not from Operator Master.
