Actiflo® (Décantation lestée)

Introduction

This tutorial provides a comprehensive guide to the Actiflo® process, a high-speed lamellar sedimentation technique using microsand to enhance flocculation. This method is ideal for treating municipal and industrial wastewater, effectively removing suspended solids, phosphorus, and organic matter.

Step 1: Understanding the Actiflo® Process

• Actiflo® utilizes microsand as an auxiliary agent to facilitate the sedimentation of flocs.
• The process involves rapid clarification and is designed to handle high loads of suspended solids (MES).
• Its compact design makes it one of the most space-efficient clarification systems available.

Step 2: Components of the Actiflo® System

• Clarifier: The main unit where sedimentation occurs.
• Flocculation tank: Where the floc formation takes place before entering the clarifier.
• Recycling system: Helps in recirculating microsand for enhanced efficiency.
• Mobile units: Available for emergency treatment or short-term applications, offering flexibility and quick deployment.

Step 3: Key Benefits of Using Actiflo®

• Efficient removal of high concentrations of suspended solids.
• Significant reduction of phosphorus levels in wastewater.
• Compact footprint suitable for space-restricted installations.
• Flexible rental options for temporary or urgent needs.

Step 4: Application in Municipal and Industrial Settings

• Municipal applications include treating drinking water and wastewater.
• Industrial uses can range from food processing to chemical manufacturing.
• The system can be tailored to meet specific treatment requirements based on contamination levels.

Step 5: Considerations for Implementation

• Assess the volume and characteristics of wastewater to determine system specifications.
• Ensure proper installation and maintenance to maximize efficiency.
• Regular monitoring of floc formation and sedimentation rates is essential for optimal performance.

Conclusion

The Actiflo® process offers an efficient and compact solution for wastewater treatment, significantly improving the removal of contaminants in both municipal and industrial settings. By understanding its components and benefits, as well as considering key implementation factors, you can effectively utilize this technology for your wastewater treatment needs.
