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 ().

2012-2-15  The coagulation–flocculation study suggests that the pH is a controlling factor for achieving high removal efficiency from the wastewaters as show from COD, TOC and turbidity values. In the present study, maximum removal was achieved by three coagulants when used in the pH range of 6.0–7.0. COD, TOC and turbidity measurements showed that ...

The targeted co-flocculation of the different pigment types therefore combats separation. Of course, on account of the possible gloss reduction and more unfavorable pigment utilization, flocculation – even a controlled one – is not particularly desired in many topcoat systems, especially high-quality ones.

Difference between Coagulation and Flocculation ...

Coagulation means to curdle; it basically refers to a chemical process in which the destabilization of non- settleable particles takes place. These particles form clump. This is done with the help of a coagulant. On the other hand, flocculation means to form flocs. It can be described as a physical or a mechanical process in which the coagulated clumps are made to join
