Effectiveness of Air Flotation Clarifiers
- Highly effective at removing suspended solids from water.
- Key tool in many water and wastewater treatment processes.
- Unique mechanism addresses particles that are too light to settle or too small for basic filtration.
Working Mechanism
- Introduces tiny air bubbles into water containing suspended solids.
- Bubbles attach to solid particles, enhanced by coagulants or flocculants.
- Bubbles lift particles upward, forming a floating layer (scum) on the surface.
- Scum is skimmed off, leaving water with significantly reduced solids.
Advantages Over Sedimentation
- Handles a wide range of particle types and sizes.
- Unlike sedimentation, it actively lifts solids rather than relying on gravity.
- Effectively removes lightweight or low-density particles.
- Breaks up stability of dispersed particles through bubble attachment.
Factors Affecting Efficiency
- Bubble size: Smaller bubbles offer more surface area for attachment.
- Type and dosage of coagulants/flocculants used.
- Flow rate of water through the clarifier.
- When optimized, achieves high levels of solids removal.
