The Turbomix® reactor incorporates the latestdevelopments in hydraulics and computational fluiddynamics into our proven MULTIFLO™ and ACTIFLO®technologies. Designed to optimize the efficiency of theprecipitation and flocculation reactions, Turbomix®ensures optimum utilization of all chemicals, enhancedreaction kinetics and a smaller tank footprint.
The Turbomix® provides:• High level of homogenization,
reducing retention time
• Removal of bypass and deadzones to achieve classicalprecipitation and flocculationefficiencies in a smaller tank
• Complete mixing of the influent water with thechemicals and recirculated sludge
• Increased pumping efficiency
• Reduced chemical and power consumption
• Easy control and maintenance of the reagentinjection system
• Maximum crystal growth
These two premier clarification processes from Veolia Water Solutions & Technologiesare combined with a unique softening draft-tube reactor to reduce hardness,alkalinity, silica and heavy metals. The addition of chemicals and controlled
sludge recirculation enhance the formation of crystalline compounds that rapidly settle in a lamella clarifier, resulting in a very small footprint.
Major Benefits of our Softening Solutions• Compact: The footprint of the high rate softening
technologies is 10 to 20 times less than that of aconventional precipitation softening system.
• Flexible and robust: The hydraulic design of thesections within the treatment unit promotes optimumflow distribution and consistent operation, achievinghigh water quality.
• Sludge treatability: The produced sludge can be easilythickened and dewatered.
• Plant-wide automation: Theprocess can be fully automatedand integrated into the plantSCADA for easy remote control.
• Application expertise: The choice ofMULTIFLO™ or ACTIFLO® softening technologydepends on your water characteristics. Ourprocess expertise will ensure the best solution foryour application.
MULTIFLO™ for SofteningThe MULTIFLO™ technology incorporates chemicalprecipitation with sludge thickening, producing ahighly concentrated sludge that can be easilydewatered. MULTIFLO™ is suitable for treating waterwith an average to high suspended and precipitatedsolids content.
Veolia provides Prefabricated Package Plants up to 700gpm or custom-engineered solutions for higher flowrates, depending on the application.
MULTIFLO™ and ACTIFLO® Softening technologies provide high rate softening in a compact design for industrial applications

ACTIFLO® for SofteningThe ACTIFLO® technology combines chemicalprecipitation with recirculated microsand, whichacts as a seed for floc formation.The rapid settling of themicrosand-ballasted flocallows for designs with veryhigh overflow rates. Theproduced sludge can beeasily thickened anddewatered. ACTIFLO® issuitable for treatingwater withaverage solidscontent, and isespecially efficientfor silica removal.
