High Rate Thickeners

Description The High-Rate thickeners became popular in the mid 1980 s and are relatively newcomers to the sedimentation line of equipment As already discussed previously Thickeners are a major component in a plant layout and occupy large spaces which may be saved by introducing high-rate machin Furthermore they are normally positioned far away from the center of the plant so to allow...

A well designed thickener provides storage and equalization and reduces the costs associated with de-watering Thickeners are similar to other circular clarifiers in appearance and operation but typically require higher operating torque and alternate sludge collection designs for optimal performance...

How a Thickener Works

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...

Improve Clarifier and Thickener Design and Operation

A design method for thickeners and clarifiers known as the batch flux curve technique was developed over 20 years ago but still is not well-known in design and operating circl An informal survey of major clarifier and thickener manufacturers found that none of the firms surveyed use this method for sizing and maximizing operating conditions...

Design Considerations for a Tailings Disposal System E MJ

A deep cone or deep bed thickener produces paste Both high density and deep cone thickeners depend on retention time rather than area Yield stress is the dividing line between paste and thickened tailings and deep cone thickeners produce a yield stress of 120 to 150 Pascals Pa and greater...

How to Size a Thickener

Knowing how to size a thickener and determine the capacity required to handle a pre-determined tonnage of a certain pulp by overflowing a clear solution and obtaining the desired pulp density of thickener discharge depends upon the settling rate of that particular pulp The settling rate of any pulp is easily determined by simple laboratory tests such as outlined below Laboratory Test...
