Veolia Actiflo - Compact Water Clarification Process System

Water clarification is a fundamental step in water treatment to remove suspended solids from water and in wastewater treatment.

Offering high-rate clarification, Actiflo is a family of products designed specifically for compact water and wastewater clarification processes.

For the production of drinking water and process water, Actiflo treats surface water, groundwater, seawater and brackish water. This ability is vital as drinking water treatment plants adapt to the impacts of climate change such as storm events and the growing importance of alternative raw water sources.

To ensure water standards are maintained, Actiflo increases the settling speed compared to conventional settling and allows treating a flow rate up to 10 times higher than the sludge bed process.

It is particularly effective in eliminating turbidity, natural organic matter, color and algae. For the specific needs of industry, Actiflo is also suitable for the treatment of cooling tower make-up water and boiler feed pretreatment.

For municipal and industrial wastewater, Actiflo can be implemented at all stages of the treatment of municipal effluents, including primary and secondary clarification, tertiary polishing and wastewater reuse.

The high-rate clarification system is based on the ballasted flocculation concept developed by Veolia. It  uses microsand and polymer in the flocculation tank to increase the weight of the flocs and hence the water clarification velocity, reaching 40 to 100 times higher velocity than conventional clarification solutions.

It helps our customers across municipal and industrial markets such as pharmaceutical, food and beverage, power, mining, chemical and more, to treat toxins and remove organic matter, and is particularly suited to the removal of heavy metals, ash and coal fines, to ensure safe and compliant water supplies.

• Fast and flexible: compact high-rate clarification system for multiple applications in water and wastewater treatment plants.
• High-performance efficiency: turbidity and suspended solids (TSS) removal up to 99%; treats all water and wastewater sources.
• Treat harmful toxins efficiently to ensure safe water supplies.
• Extremely quick start-up time: reaches treatment efficiency within a few minutes.
• Process stability: capable of handling sudden variations in flow and load.
• Numerous standard options and alternatives to enhance performances and monitoring.
• Extremely compact footprint and start-up times account for savings in construction materials and water.
