Sludge Thickening - an overview | ScienceDirect Topics

A flotation thickener, shown in Figure 9-5, operates by forcing air under pressure to dissolve in the return flow and releasing the pressure as the return is mixed with the feed. As the air comes out of the solution, tiny bubbles attach themselves to the solids and carry them upward, to be scraped off.

Concentrate Dewatering & Thickening

The concentrate from the flotation section usually contains only 20 to 30% of solids as it leaves the cleaning machine and must be dewatered before being sent to the next department. The operation of dewatering is performed in two stages. First, the bulk of the water is removed in a thickener, from which the concentrate is discharged as a thick pulp ; as a rule the underflow contains 55 to 65% ...

maximum allowable solids loading for the thickener to work successfully. When flux is at minimum, we calculate for the maximum area required. If this limit is exceeded, the solids will overflow in the effluent. So the design of a thickener is thus reduced to the point of determining this flux. Then to find G L
