Highly effective treatment
Designed to treat and refine water, Actiflo Carb combines the fast flocculation and sedimentation performance of Actiflo with the adsorption capacity of Powdered Activated Carbon (PAC) to eliminate substances resistant to the clarification process. The adsorbent properties of PAC offer an effective solution for the elimination of non-flocculable Natural Organic Matter (NOM), micro-algae, flavors and odors, pesticides, endocrine disruptors and other emerging micropollutants in the water to be treated. The unparalleled performance of Actiflo Carb produces water of very high quality.
The Actiflo Carb process
The operating characteristics of Actiflo Carb are identical to those of Actiflo, giving it the advantages of fast, high-performance treatment. Upstream of the coagulation, flocculation and sedimentation basins, Actiflo Carb has a PAC contact tank to adsorb pollutants resistant to chemical clarification. A recirculation circuit with a specific hydrocyclone recovers clean microsand, returns the PAC to the contact tank and purges excess sludge from the process.
Actiflo Twin Carb, a dual-stage treatment
Depending on the quality of the water to be treated and the performance to be achieved, the Actiflo Carb process is also available in an Actiflo Twin Carb version. This unique configuration consists of a dualstage treatment in series, amplifying the elimination of NOM and reducing the footprint. This dual-stage treatment involves an Actiflo clarification stage followed by an Actiflo Carb refinement stage. Particularly well-suited to treating water with a high pollutant content, Actiflo Twin Carb can reduce a Total Organic Carbon (TOC) level of 15 mg/l in the raw water to less than 2 mg/l in the treated water.

Applications of ACTIFLO® CARB Powdered Activated Carbon
Actiflo Carb is recommended for:

Drinking water: for the treatment of NOM resistant to clarification, pesticides, emerging micropollutants, micro-algae, flavors and odors
Process water: for refining and treating resistant NOM
Sewage: to eliminate hard Chemical Oxygen Demand (COD) and other compounds resistant to chemical or biological treatment systems
“Reuse”: for the advanced tertiary treatment and refinement of treated sewage.
