Thickening of sludge increases its solids content and reduces the volume of free water thereby minimizing the unit load on downstream processes such as digestion and dewatering The most commonly used thickening processes include gravity thickening, dissolved air flotation, and rotary drum thickening
Thickeners are used for dewatering slurries of either tailings or product A thickener is a large circular tank that is used to settle out the solid material from the water in the feed slurry The separated water is clarified and reused as process water in the CPP Thickeners are sized according to the volume of feed slurry to be processed
xvEPA United States Environmental Protection Agency Biosolids Technology Fact Sheet Gravity Thickening DESCRIPTION Thickening is the process by which biosolids are condensed to produce a concentrated solids product and a relatively solids-free supernatant
The sludge is compressed at the tank bottom only by the force of gravity, while above the sludge a cloudy water layer is formed, which is taken off and led back into the inlet On larger plants separate thickening basins exist These basins are equipped with slow rotating vertical rods, which create micro canals in the sludge for a better .

For bridge and column type thickeners with tanks that are mounted on ground level the access to the slurry pumps is trough a tunnel For very large column type thickeners the column is constructed as a caisson that is submerged in the slurry so that the pumps are housed at the bottom of the chamber and deliver the underflow upwards
Thickener Tanks GAST The thickener tanks can be described as an upright, cylindrical steel tank at zero pressure The conical bottom has an outlet connection on one side and a flange that can be used for flushing or connection of a pressure gauge on the other side Live Chat
How a Thickener Works Thickening or dewatering may be defined as the removal of a portion of the liquid from a pulp or slime made up of a mixture of finely divided solids and liquids The early methods of thickening employed plain, flat-bottomed tanks into which the pulp was fed until the tank was full
Product Application of high quality mining sludge thickener tank for tailing process The mining thickener is widely used not only for concentrates thickening and tailings dewatering before filtration on mines,but also for thickening and purifying of solid slurry in industries of coal,chemical,construction,waster supply,and waste water treatment
The thickener has a peripheral walkway that allowed convenient access to the instrument and provided the ability to make manual bed level readings at any angular position around the tank Current thickener control is based on the operator conducting manual bed level reading every four hours
