Actiflo™

Product catalog summary

Introduction
Veolia Water Solutions & Technologies presents Actiflo®, a high-rate clarifier designed for efficient water treatment. It utilizes microsand (Actisand™) to enhance flocculation and settlement, making it suitable for various applications including drinking water, process water, and wastewater treatment.

Specifications and Process Overview
Actiflo® operates with a compact design, achieving high treatment efficiency with a removal rate of over 90% for turbidity. It is adaptable to changing water quality and can be automated and remotely controlled. The process involves coagulation, ballasted flocculation, and settling, with a very short start-up time of less than 10 minutes.

Applications

Drinking Water: Effective in removing turbidity, color, algae, and arsenic, with upflow velocities of 40-80 m/hr.
Wastewater: Consistently produces high-quality effluent, removing over 90% of total suspended solids, phosphorus, and heavy metals.
Industrial Effluents: Suitable for solids and color removal, heavy metal removal, and lime soda softening.
Stormwater Treatment: Handles peak flows efficiently, often combined with UV disinfection for compliance with stringent water directives.

Performance and Efficiency
Actiflo® offers a significantly smaller footprint compared to traditional clarifiers, with designs allowing for overflow rates greater than 40 m/hr. It is effective in various conditions, including low temperature and fluctuating water sources.

Case Studies and References
Actiflo® has been successfully implemented worldwide, including in Sydney, Australia for storm flow treatment, and in Paris, France for both storm flow and tertiary treatment. Other notable installations include drinking water treatment in Calgary, Canada, and wastewater treatment in Liverpool, UK.

Modular and Mobile Solutions
Veolia offers Actiflo® package plants for small to medium-sized applications, which are modular and can be quickly installed. Mobile plants are also available for temporary treatment needs, providing flexibility and rapid deployment.

Conclusion
Actiflo® by Veolia Water Solutions & Technologies is a versatile and efficient solution for water treatment, offering high performance in a compact design suitable for a wide range of applications.
