Design method of continuous thickeners from semi-batch

An extension of a previous method for designing continuous thickeners is presented The previous method was based on data obtained for batch testing, where the discontinuity heights corresponding to the supernatant-suspension and to the top of the sediment are known at different values of time

Measuring Settling Rates and Calculating Thickener Capacity

In the operation of continuous thickeners, the feed of the thin pulp at the center of the tank, the overflow of clear liquid at the periphery of the tank, and the discharge of the thickened pulp at the bottom, are generally continuous In a continuous thickener, the four zones previously described in discussing intermittent settling are generally present as shown in Fig 2 At the top there is

THICKENERS - Thermopedia

Thickeners vary widely in size and configuration, but they all comprise: a a vessel to provide volume and area needed for thickening, with the area being large enough to allow the solids to settle at a velocity faster than the upward velocity of the liquid; b a system for introducing the feed and directing it into the flow paths that best utilize the vessel volume and area; c an overflow system for collecting clarified …

Conventional Thickeners - Solid Liquid Separation

Conventional Thickeners are generally incorporated in heavy duty applications when the underflow density is high and substantial torques are required to convey the settled solids from the periphery to the central outlet for pumping away Likewise, thickeners are often used for storage to facilitate the continuous feeding of downstream filters or centrifuges

Improve Clarifier and Thickener Design and Operation

Figure 1 Flow scheme for clarifiers and thickeners The feed flowrate (Q f) and concentration (x f) are normally design parameters This leaves the designer or operator to determine the underflow pumping rate (Q u) (sometimes called blowdown) required to achieve a desired underflow effluent concentration (x u) Since the underflow is normally pumped, this variable can be controlled during operation Also, the …
