Flocculator Mixer and Low-Shear Agitator | FRH Helisem Mixer

The FRH Helisem mixers are low-shear agitators and flocculators preserving floc structure and sensitive product integrity for optimal process efficiency:

Flocculation

In wastewater treatment plants, flocculation is a crucial step in grouping fine particles into denser flocs, facilitating their separation by settling or flotation. Thanks to its low-shear design and patented HP2 turbine, the FRH agitator ensures gentle, controlled agitation that preserves the integrity of the flocs, guaranteeing maximum efficiency of the physico-chemical treatment.

Homogenization

In drinking water production processes or in industry, maintaining a uniform composition in the tank is essential to ensure the quality of the finished product. The FRH ensures regular mixing without degrading the constituents, allowing effective homogenization even in large volumes or with viscous liquids. It thus helps to stabilize formulations and prevent deposits or phase separation.

Dissolution

To effectively dissolve powders, salts, or polymers in a liquid, regular and gradual agitation is necessary. The FRH excels at this task thanks to its fluid motion, which promotes optimal contact between solids and liquids without creating dead zones or generating excessive foam. It is particularly well suited to the preparation of reactive solutions or the conditioning of industrial water.

Storage

During storage, certain fluids must remain in motion to prevent settling or the formation of surface crusts. FRH mixers, which can operate at very low speeds and be controlled by a frequency inverter, provide economical maintenance mixing that prolongs product stability while reducing the risk of contamination or precipitation.

Reagent preparation

FRH agitators are also perfectly suited to the preparation of chemical reagents used in treatment plants (coagulants, flocculants, acid and alkaline solutions, etc.). Their corrosion-resistant 316L stainless steel design and optional Abcite® coating ensure long life even in aggressive environments. Mixing is homogeneous, reproducible, and carried out under optimal safety conditions.
