Study Notes
Aeration
- Aeration removes dissolved gases, improves water taste, and oxidizes contaminants.
- Gravity aerators use gravity to facilitate gas exchange.
- Spray Aerators atomize water to increase contact with air.
Sedimentation
- Plain Sedimentation relies on gravity to settle suspended solids.
- Coagulation enhances sedimentation efficiency by using coagulants like aluminum sulfate and ferric chloride.
- The correct coagulant dosage is determined through a Jar Test.
- Flocculation aggregates particles into larger flocs to facilitate removal.
- A Clari-Flocculator combines coagulation, flocculation, and sedimentation in one tank.
Sedimentation Tank Design
- The surface loading rate is a critical parameter for determining tank size and capacity.
- Simple problems can be used to calculate sedimentation tank design.
