Continuous Thickening Theory

28/01/2018  In a continuous thickener the downward solids velocity with respect to the thickener wall is the sum of the settling velocity of the solids by gravity alone, Vi, plus the downward velocity caused by removal of the thickener underflow, U. The rate at which solids move downward by gravity alone is expressed as the product of the concentration of the solids in a layer, Ci, and the settling ...

Thickening - Resource Book

Continuous thickening by an operation called sedimentation is the separation of suspended solid particles from a liquid stream by gravity settling. The primary purpose of thickening is to increase the solids concentration of the feed stream. Gravity settling is aided by addition of chemicals called flocculants. The inlet stream going to a thickener generally is called ‘feed’ or ‘influent ...

Texipol inverse emulsions are manufactured directly from the pre-neutralised liquid monomers that are intimately dispersed in the oil phase followed by a controlled polymerisation process to yield the liquid thickener.

Thickeners - Solid Liquid Separation

Rake driven thickeners for continuous operation can impose a substantial burden on capital investment. Unlike many other types of equipment, thickeners have no stand-bys so if one goes out of commission it cannot be by-passed. Consequently, if this happens other thickeners have to take the extra load but if the plant incorporates just one thickener then the entire production line must stop. To ...

Sizing and Operating Thickeners

02/06/2017  The model is verified by continuous thickening data on several types of slurries. When batch tests are run and analyzed correctly, excellent agreement is achieved between predicted and observed results unless the effect of compression forces becomes too great. When compression forces are significant, the model comes close to predicting the continuous results if the batch tests are

Continuous Consolidation of Sludge in Large Scale

Improved design and performance of continuous thickeners should be achieved through a better understanding of the sludge transport processes involved and the variability of sludge thickenability. A software package called PHOENICS was used to model the three-dimensional flow of sludge in the transport zone of a 20m diameter thickener. A mass transport efficiency was evaluated to test the ...

Kynch's theory of sedimentation is adopted to solve for the attainable steady state concentration in a vertical continuous sedimentation basin incorporating a thickener and a clarifier. The limiting flux solution corresponding to the local minimum at the flux concentration curve is proved to have a limited range of validity and is shown to apply only to the intermediate range of feed ...

The Conventional Thickener - Solid Liquid Separation

Thickener tanks may be constructed either from steel or concrete and may reach diameters of 120 meters and in earthen basins up to 180 meters. Most of the chemical process industries prefer the steel tanks construction since they may be elevated above ground level, allow inspection of the tank's floor for leakages and bring the underflow slurry pumps nearer to the outlet of the discharge cone.
