The High Rate Thickener - Solid Liquid Separation

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 machines. Furthermore, they are normally positioned far away from ...

The object of a control system on a High Rate Thickener (HRT), as on a conventional thickener, is to obtain the required underflow density and overflow clarity at all feed conditions. The feed conditions, which may vary, include volumetric and mass feed rate…

Paste Thickeners | McLanahan

Thus, Paste Thickeners are commonly run at a higher rise rate than a conventional or High-Rate Thickener (either using more flocculant or accepting more solids in the overflow), giving the appearance of having a higher capacity.

Paste thickener benefits for soda ash: liquor recovery ...

*HRT = high rate thickener; PT = paste-type thickener These actual performance values show a dramatic increase in underflow wt% between high rate thickeners and paste-type thickeners. Increasing the underflow from about 28 to over 50 wt% recovers about 70% of

The key advantages of a High Rate Thickener over a conventional thickener are as follows: Some of key features of the MBE High Rate Thickener are • The HRT is designed specificallyto operate with flocculantsand hence optimises flocculant consumption.

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 ...

Difference Between Clarifier and Thickener

The Difference Between a Clarifier and a Thickener is subtle as they will visually look the same. Fundamentally, thickeners and clarifiers are both used to settle solids which results in the separation of liquids and solids. Thickeners are used to concentrate solids, while clarifiers are used to purify liquids. A thickener will give you a high density underflow while a clarifier will not.

Beginners Guide to Thickeners - Outotec

In high rate thickener (HRT) designs the rise rate or solids loading will dictate the required tank diameter for any given throughput. In high compression (HCT) and paste (PT) applications the bed depth or the mass of solids in the thickener must also be selected to ensure the desired underflow density from the thickener is achieved.

Flocculant Usage in Hight Rate and Conventional Thickeners ...

It is the commonly held belief that, because the separation of liquids from solids takes place considerably faster in high rate thickeners than in conventional thickeners, high rate thickeners (HRT's) must use more flocculant than conventional thickeners.
