Ovivo thickeners are available in two types: CST (column supported thickener) and BST (bridge supported thickener). The thickeners can be tailored to meet the specific demands of a customer's process. They can also be designed to fit into new or existing thickener tanks. Ovivo circular thickeners have been used in thickening for over 80 years.

Rake thickeners are designed specifically to deal with high volumes of slurry. The integral scrapers aid transportation of material from the periphery of the tank to the outlet, thus accelerating the removal of sludge from the thickener. KEY FEATURES. Produces sludge with 30 - 40% solids content; Low level feed in height to enable gravity feed

Thickeners: How they Operate. The most common solids-liquid (S/L) unit operation is thickening. A wide variety of thickeners are used including conventional, deep well, paste, high rate and clarifiers which is a thickener subclass used for removing solids from …

Tanks range from 6 – 20 m dia & side water depth (SWD) may vary from 3 – 4 m. Floor slope is varies from 1:4 to 1:6 depending upon the type of sludge, time required for thickening & storage volume to absorb peak solids load. The steeper slope reduces the raking problems by providing more gravity.

secondary settling tanks. Reading time: 25 minutes. These settling tanks are often termed clarifiers and are used in activated sludge systems for separating treated water from biomass, settling sludge and sufficiently thickening it so that when the sludge is returned to the tank inlet, it can maintain the biomass concentration levels required.

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 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 of 4% solids, then a fivefold decrease in sludge volume is achieved [1]. ...

Gravity thickening is a process in which solids are left to settle in a tank under the influence of gravity. It is widely used in China [7,51] and tends to be the least …

Thickeners. Thickeners — or Clarifiers, depending on the application — can be used to recover immediately reusable process water, as well as extract fines and other materials. Thickeners are used by mineral and aggregate producers, as well as by environmental contractors in industries such as wastewater management, to separate solids from liquid in a slurry.

The Dorr traction thickener is the type most frequently used for heavy- duty work with large tonnages. The machine is so called because the thickening mechanism is driven by means of a traction wheel which travels around the periphery of the tank on a rail.

This results in less % solids in the thickener discharge. In this case, the control loop decreases the pump speed in order to increase the mud level, consequently increasing the %solids in the discharge. Table 1 summarizes the most common problems in …

The thickener body, or tank, is a thickener's most obvious elem ent and its shape indicates its desig n priorities. For a given flowrate, t hickeners in a clarification duty w ill have large ...

Many industries use a circular steel tank called a thickener or a clarifier or a circular collector. Dorr is one manufacturer. Another, that I prefer, is the Walker Process, a subsidiary of Chicago Bridge and Iron where I worked for 34 years. These tanks are used in many industries: mining, pulp and paper, sewage plants, sugar mills and steel ...

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 employed in septic tanks. Settling-thickening tanks for FS treatment are rectangular tanks ...

The thickeners must be preceded by flow balancing tanks to contain and mix intermittent sludge discharges and feed the thickeners at a consistent concentration and uniform rate (Fig. 13.1). In applications where used washwater (without settlement) is mixed with clarifier sludge, the sizing of the flow balancing tanks becomes critical because of ...

Belt filter thickener can be used instead of conventional gravity thickening tanks to increase the dry solids content of the slurries. ASTiM belt filter thickener works as a heavy-duty thickener, ...

Tank construction can vary from precast concrete, circular steel tanks, to glass lined concrete tanks depending on budget and requirements for the plant. 1) At the centre of each Picket Fence Thickener is a Motor or Drive used to rotate the mechanism through the sludge.

The thickening tank is equipped with slowly moving vertical paddles built like a picket fence. Sludge is usually pumped continuously from the settling tank to the thickener which has a low overflow rate so that the excess water overflows and the sludge solids concentrate in the bottom. A blanket sludge is maintained by controlled removal which ...

This unit is typically used to remove solids from industrial waste and process waters. For municipal treatment plants, they are often used to clarify and remove solids from sand filter backwash water and other filtration processes. Optional equipment includes skimmer, drag conveyors, chemical treatment, flocculator, thickener, and control panel.

Thickeners are used to concentrate solids, while clarifiers are used to purify liquids. A thickener will give you a high density underflow while a clarifier will not. The clarifier overflow is typically cleaner or clearer than the thickener overflow would be. Clarifiers, depending on the application – that can be used to recover immediately ...

• The solids load escaping in the liquid portion from the blending tank is taken as 10 • Thus, the solids load entering the sludge thickener becomes 112.1 • The solids load escaping in the liquid portion from the thickener is taken as 11.2 • The solids load leaving the thickener becomes 100.9.

Thickener/clarifier settling tanks are used in a wide variety of industries to separate influent feed slurry comprising a solids, or particulate material, containing fluid to produce a "clarified" liquid phase having a lower concentration of solids than the influent feed slurry and an underflow stream having a higher concentration of solids than the influent feed slurry.

Beginners guide to thickeners. Thickening is a process where a slurry or solid-liquid mixture is separated to a dense slurry containing most of the solids and an overflow of essentially clear water (or liquor in leaching processes). The driving force for the separation is gravitational, where the differences in phase densities drive the ...

Thickeners are used for increasing the solids content of a slurry. The general objectives are ... specific gravity is an indication of the amount of solids in the tank and can be converted into a rough solids inventory. This can be a very effective tool for thickener control. Because of
