Conventional Thickeners - Solid Liquid Separation
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.

The tank is built in 2 sections, an upper and lower section, for ease of transport. The tank requires only 2 flat bed trucks and width permits for hauling.
How a Thickener Works - Mineral Processing & Metallurgy
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. The solids were then allowed to settle as long as required, the top liquid was decanted, the settled solids were ...
What is the Sludge Thickening Process in Water Treatment ...
Mar 06, 2018· Thickening tanks have slow-moving vertical paddles. Sludge flows into the thickening tank, and eventually, it removes excess water from the solids collecting at the bottom. A gravity thickener has a similar process to the tanks, but it has a sloped design so that solids collect at the base.
Thickeners - Haywards Steel

Recently, the design has progressed to the bolt together type of thickeners providing the end user with a product that can be erected on site more ...
Visual Encyclopedia of Chemical Engineering
Thickeners and clarifiers use slowly rotating rake arms to separate solid particulate. A liquid feed with suspended solids is fed into a tank with a diameter of 5 to 500 feet. As the particles settle, angled rake arms move the concentrated slurry toward the center of the tank, where it is removed.
Thickening - lenntech.com
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 ...
Biosolids Technology Fact Sheet Gravity Thickening - EPA
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.
FSM H06 CS5 - un-ihe.org
Settling-thickening tanks are used to achieve separation of the liquid and solid fractions of faecal sludge (FS). They were ﬁ rst developed for primary wastewater treatment, and for clariﬁ cation following secondary wastewater treatment, and it is the same mechanism for solids-liquid separation as that
Deep Cone Thickener, Sludge Thickening Tanks | LZZG
High-efficiency thickeners for sludge dewatering. The deep cone thickener is based on the traditional vertical flow sedimentation tank. The structure of the internal feed cylinder is improved, the efficiency of sedimentation is greatly improved, the plane of the sludge thickening tank body is circular, and the suspended solids settle under gravity.
Sludge Thickeners | Hoffland Environmental, Inc | (936 ...
The HEI thickener’s compact design provides greater storage capacity and more retention time for greater thickening of solids with less height. A equivalent cone bottom tank would add an additional 10 feet of height. For example, an HEI 8ø x 12 thickener contains 4520 gallons.

Sludge Thickening - Degremont®
Thickening is the first, and frequently inevitable, step in reducing the volume of sludge extracted from the water line. In fact, it is used to optimise the subsequent conditioning, stabilisation and dewatering stages by reducing structure sizes and operating costs.
CHAPTER 3 SLUDGE THICKENING - Marmara Üniversitesi
CHAPTER 3 SLUDGE THICKENING Thickening is a procedure used to increase the solids content of sludge by removing a portion of the liquid fraction. To illustrate, if waste activated sludge, which is typically pumped from secondary tanks with a content of 0.8% solids, can be thickened to a content
Clarifier - Wikipedia
Clarifiers are settling tanks built with mechanical means for continuous removal of solids being deposited by sedimentation. A clarifier is generally used to remove solid particulates or suspended solids from liquid for clarification and (or) thickening. Concentrated impurities, discharged from the bottom of the tank are known as sludge, while the particles that float to the surface of the ...
