This document provides an overview of various clarifier and thickener systems for treating water and wastewater. It describes central drive, peripheral drive, and traveling bridge configurations for circular, rectangular, and reactor clarifiers. It also discusses gravity thickeners, dissolved air flotation thickeners, and gravity belt thickeners. A wide range of clarifier and thickener ...
The document discusses thickener feedwell design. It notes that most current feedwell designs do not achieve key objectives like efficient mixing and flocculation. Large diameter feedwells are prone to short-circuiting which reduces performance. A new vane feedwell design is introduced that features two mixing zones, controls dilution flows, and promotes even aggregate …

Starting with the basics of thickener theory, key elements of the sedimentation process and options for thickener selection are explored, as well as testwork requirements and the features …
concentration of the feed to the thickener and applying equation (6) to find the area S of the thickener. As we have already discussed, the concentration in the zone II of the thickener is not that of the feed and therefore equation (4) is not correct invalidating Mishler's method of thickener design. 2.2 Coe and Clevenger's method.
Abstract This chapter presents different theories of thickener design. These the-ories have been applied to the solution of the same problem, wherever applicable, to reveal the relative …
traction thickeners are an efficient, cost-effective design. Thickener tanks Tank options include in-ground, on-ground, anchor channel or elevated steel. Steel tanks are available as welded or bolted designs. High-rate thickeners In developing our high-rate thickeners, we draw upon decades of experience in flocculation, feed dilution, and ...
The document provides instructions for sizing a thickener based on laboratory tests to determine pulp settling rates at different densities. Key steps include: conducting settling tests at initial, intermediate, and final densities; calculating …

Thickener design theory has many unresolved problems and areas of uncertainty. This document outlines what is known and unknown about thickening regimes, including zone settling, phase settling and compression. It also discusses …
Thickener outputs can accommodate a range of tailings disposal options from low yield stress, easily pumped suspensions for disposal in conventional 'wet' tailings dams to more …
Design Procedure The thickener area is also required for this calculation. Guess the thickener area for the first iteration. Several iterations of area may be required to achieve a practical thickener size and pumping rate. For a circular thickener with a 15.24 m (50 f …
Thickening is the process of separating parts of the liquid of a suspension so as to obtain a denser product and a flow of pure liquid. The objective of the process may be focussed on …
Thickener Design - Free download as PDF File (.pdf), Text File (.txt) or read online for free. This document provides information about designing a thickener to treat effluent. It gives settling curve data for a suspension at 3% solids and asks the designer to calculate heights, velocities, and fluxes. The critical flux is then calculated to be 7.2x10-7 m/s, requiring a minimum area of …

This document discusses the design of paste thickeners based on downstream requirements. Paste thickener design is determined by requirements for deposition, pumping, and process feed rate and characteristics. Pilot testing is used to determine rheological properties like yield stress, and these properties guide the design of the thickener and downstream transportation system. …

The structural design of a tailings thickener was reviewed using finite element analysis (FEA). [1] The FEA model analyzed stresses on the rake arms, central torque cage, and octagonal ring under different torque and bridge position conditions. [2] The results showed the connection points between the rakes and torque cage experienced the highest stresses, especially when …

7. The centrally driven thickeners are further classified into two types a. Column Type Thickeners A kind of thickener where a central steel or concrete column takes vertically the reaction to the weight of the mechanism and horizontally the torque load. b. Bridge Type Thickeners In the bridge type a structure spans across the tank and is subjected vertically to …
Perhaps the most significant design optimisation effort in thickening in the last twenty years has been in developing ways to more effectively use the horizontal cross sectional area of the thickener. The introduction of polymeric flocculants gave an impetus to development of High Rate Thickeners. The result is now common use of the term ...
