Description:
The thickener is used to increase the concentra-
tion of the suspension by sedimentation, accompa-
nied by the formation of a clear liquid. In most
cases the concentration of the suspension is high
and hindered settling takes place. Thickeners may
be batch or continuous units, and consist of rela-
tively shallow tanks from which the clear liquid
is taken off at the top, and the thickened suspen-
sion at the bottom.
The feed slurry enters the feed well tangentially through the feed pipe. The feed slurry is pumped or fed by
gravity to the thickener and shall have the energy to aid mixing of flocculant solution with it.
The feed well is sized adequately to take care of the venting of the entrapped air in the feed slurry. The de-aerated and flocculated feed is then discharged through the annular gap formed between the feed well and the
deflector plate at a predetermined velocity into the main body of the thickener.
This ensures the distribution of flocculated feed radially in one plane across the full thickener area, aiding proper
separation of solid liquor.
As the solids settle down, the scrappers of rotating rakes scrap the solids towards the underflow cone for
withdrawal. Liquor component raises to the upper part of the thickener to flow into the overflow launder.
