The FF (flocculation–flotation) process - ScienceDirect

2005-6-1 · 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 ().
