Thickeners. 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.It is widely used for dealing with slime, wastewater, waste residue in metallurgy, mine, coal, petrochemical industry, building materials, environmental protection department etc.
White paper Debottlenecking of Thickeners in a Changing Environment 2 In assessing the decision to modernize, we consider the elements of an upgrade and the advances in thickening technology that allow operators to meet new challenges. Finally, we will discuss the process of modernizing a thickener so as to achieve the clients stated outcomes.
OPERATION AND MAINTENANCE Operators should monitor operating parameters in the gravity thickener to ensure optimum performance. Routine monitoring should include the following Sample the feed solids and the thickened solids once per day and analyze for TS.

Thickeners. The separation of solids from a liquid by gravity sedimentation has traces to the early days of civilization. The normal practice at those times was to use jars or pits mainly for the clarification of extracted liquids such as wine or olive oil from contaminating insoluble matter.
Extracting Geometry . Sometimes, you will need to use the Extract command to be able to add thickness to a face. The Extract capability lets you generate separate elements from initial geometry, without deleting geometry. This command is available after clicking a dialog box prompting you to deactivate the Thick Surface feature and extract the geometry.
If the surface you want to thicken is comprised of multiple adjacent surfaces, you must first knit the surfaces together before you thicken the surface. To thicken a surface Click Thicken on the Features toolbar, or click Insert, Boss/Base, Thicken. Under Thicken Parameters, do the following In the graphics area, select a Surface to Thicken.
Figure 1 Typical positioning of a thickener's critical parameter measurement devices. Large tanks, known as thickeners, are used to separate fine suspended mineral particles from the process water, producing a stream of clarified water from the top of the thickener overflow and a thick sludge of settled solids (underflow) from the bottom.
The Volute Thickener is perfect for automated sludge wasting from biological processes and thickening prior to storage, digestion, further dewatering, or transport, giving a solids output from 3% to 12%. The unit can be completely automated, uses very little power, and
A bewildering number of continuous thickeners and clarifiers are used in mineral industries and other heavy industries. General types are Conventional Thickeners; Thickeners with Flocculating Feedwells; Solids Contactors; Tray Thickeners; Lamellas; Conventional Thickeners
PRACTICAL DESIGN CRITERIA. In the pre modelling era, engineers developed various complex criteria, which, as they believed, describe the state and the maximum acceptable loading of clarifiers. In addition, they developed geometrical and other recommendations.
Both thickener underflow and supernatant flows were inventoried in separate storage tanks to permit calculation of pertinent thickener operating and performance parameters. SLUDGE THICKENING AND DEWATERING PROCEDURES Dissolved Air Flotation Thickening Bench scale dissolved air flotation (DAF) thickening evaluations were performed on all sludges
The measurable parameters that can be used for thickener control include thickener feed flow rate, feed density, underflow density, overflow clarity, bed level, bed mass, rake torque, rake height, solids settling rate and underflow rehology.
Thickener design procedure and method (13 replies and 4 comments) In the tests of the laboratory we determine what we call the terminal speed, the diameter and the height of a clarifier or sedimentation tank. The team, materials and disposition of the pipe and required controls enter of specialists in the plan and construction.
Jul 11, 20160183;32;Paste Thickener Design Variables Paste thickeners are uniquely different than conventional and high rate thickeners. High rate thickeners, that produce a settling slurry underflow, have been in use for decades. Thickener selection is based on feed characteristics and standard bench scale tests combined with experience.
In designing a thickener, the desired feed flow rate F and underflow concentration D, together with the thickening parameters f bk (), c and e () and the solid and liquid densities s, f must be known. With these values, the function G(, D) can be calculated for any value of . Download full size image; Fig. 6. Algorithm for the design of a continuous thickener.
Continuously operated clarifierthickener (CT) units can be modeled by a non linear, scalar conservation law with a flux that involves two parameters that depend discontinuously on the space
The parameters that control shear thickening behavior are particle size and particle size distribution, particle volume fraction, particle shape, particle particle interaction, continuous phase viscosity, and the type, rate, and time of deformation.
The common parameters for dissolved air flotation process are tabulated in Table 7.1. Gravity thickeners are essentially circular primary settling tanks with or without mechanical thickening devices. The dilute sludge is fed into the settling tank where solids are allowed to settle over a few days.
1.3. Parameters that influence the dewatering abilities of sludge Several parameters concerning the sludge will influence its ability to dewater easily. Amongst these, the main ones are 1.3.1. Concentration (g/l) Measured in g/l, the concentration of the sludge will influence The incorporation of the flocculant. The higher the concentration
A thickener has several basic components a tank to contain the slurry, feed piping and a feed well to allow the feed stream to enter the tank, a rotating rake mechanism to assist in moving the concentrated solids to the withdrawal points, an underflow solids withdrawal system, and an overflow launder.
Recommendations. The material properties include the compressive yield stress, Py (), and the hindered settling function, R (). Py () reflects the suspension network strength as a function of solids An algorithm has been developed to predict steady state thickener
Design objective. The objective is to determine the area of a thickener, the optimum underflow pumping rate, and the corresponding underflow concentration. The following data were taken Q f = 177,600 kg/h; x f = 5 kg/m 3; and [density], p f =1,000 kg/m 3 .
