The FF (flocculation–flotation) process ScienceDirect
The flocculation–flotation system (FF ®, Rubio et al., 2003) is composed of a turbulent “flocculator” to generate aerated polymeric flocs coupled with solid/liquid, solid/liquid/liquid 2 or liquid/liquid 2 separation devices (columns, tanks, centrifuges). Here, the basic concept is that of a reactor (zigzag or static mixer types) of flocculator and a floc flotation separator ().

Coagulation and floculation describe the chemical process of contact and adhesion whereby the particles of a dispersion (colloids) form larger-size cluster (flocs or flakes) allowing them to be more easely removed from water (e.g. by settling). The coagulation-flocculation processes facilitate the removal of suspended and colloidal particles.

Dissolved air flotation Wikipedia
Dissolved air flotation (DAF) is a water treatment process that clarifies wastewaters (or other waters) by the removal of suspended matter such as oil or solids. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank basin. The released air forms

Coagulations and Flocculation Water Treatment SUEZ
Flocculation water treatment is the process of bring together the destabilized, or “coagulated,” particles to form a larger agglomeration, or “floc.” Flocculation, the agglomerations of destabilized particles into large particles, can be enhanced by the additional of high-molecular-weight, water-soluble organic polymers. These polymers
