With more than 500 plants equipped with Multiflo™ around the world, Veolia Water Technologies benefits from unrivaled feedback enabling it to offer a very broad offer to meet the most diverse demands and requirements.
Thanks to its multiple options, Multiflo™ SERIES (Mono, Mono Plus, Duo and Trio) covers many applications and can be integrated into many treatment lines, while producing a highly concentrated and thickened sludge.
Multiflo™ SERIES is ideal for small and large scale applications. It makes it possible to treat water that is more or less concentrated, homogeneous or mixed and whose pollutant load varies.

Multiflo™ is particularly effective in the production of drinking water by eliminating suspended solids (MES), color, algae, co-precipitated heavy metals.
Multiflo™ is suitable for treating water with medium or high turbidity (10 - 4,000 mg/l SS) and produces water with turbidity < 3 NTU, depending on the quality of the raw water.
Multiflo™ Softening: the Multiflo™ decanter is a decarbonation and softening process that uses lime or soda as reagents. The sludge obtained is directly concentrated and thickened in the structure to significant values (60 to 100 g/l). It can be used in drinking water, in the production of process water or in the treatment of waste water.
Multiflo™ Carb uses PAC (Powdered Activated Carbon) in a dedicated pre-contact tank. Then the PAC circulates through the structure and ends up settling under the lamellar zone. The contact time of the CAP is thus maximized. Multiflo™ Carb is a refining treatment process in drinking water, capable of eliminating pesticides, natural organic matter (NOM) and new emerging pollutants (endocrine disruptors). Multiflo™ Carb can also be used in bleaching and tertiary treatment of organic materials in industry.
Multiflo™ is also used in the primary, secondary or tertiary treatment of wastewater and rainwater for the partial or extensive elimination of suspended solids, phosphorus and carbon pollution .

Applications of MULTIFLO™ Decanter
Designed to optimize the efficiency of the Multiflo™ Duo and Trio processes, Turbomix™ ensures maximum use of polymers and a reduction in the footprint of the flocculation tank.
The presence of Turbomix™ promotes:

A high level of homogeneity ensuring a better distribution of residence times
Elimination of by-passes and dead zones guaranteeing an efficiency equal to the classic flocculation system in a smaller tank
Complete mixing of influent with recirculated sludge and chemicals, depending on applications
The increase in the pumping rate, at equal power
Reduction of polymer consumption
Easy control and maintenance of the reagent injection ramp
