Techniques

Chapter 1: Techniques

Solids Contact Clarification: The Heart of Clear-Flow

Clear-Flow technology relies heavily on the principles of solids contact clarification. This technique combines multiple processes to achieve efficient solids removal from water:

• Coagulation: Chemical agents are added to water to neutralize the surface charge of suspended particles, causing them to clump together.
• Flocculation: Gentle mixing encourages the coagulated particles to form larger, heavier flocs, making them easier to settle.
• Sedimentation: The water is slowed down, allowing the heavy flocs to settle to the bottom of the clarifier.

How Solids Contact Clarifiers Work:

1. Inlet: Wastewater enters the clarifier, passing through a series of baffles that distribute the flow evenly.
2. Coagulation & Flocculation: Chemical coagulants and flocculants are added to the water to promote particle aggregation.
3. Contact Zone: The water flows through a specially designed contact zone where the flocs can settle out and create a "blanket" on the bottom of the clarifier. This blanket enhances further sedimentation by filtering out remaining suspended solids.
4. Sedimentation: The clarified water flows slowly through the clear well, allowing the remaining suspended solids to settle to the bottom.
5. Sludge Removal: The settled sludge is collected and disposed of or further treated as necessary.

Advantages of Solids Contact Clarifiers:

• High Efficiency: Achieves superior solids removal compared to traditional sedimentation tanks.
• Compact Design: Can be installed in confined spaces, ideal for retrofitting existing facilities.
• Low Maintenance: Robust design minimizes downtime and maintenance requirements.
