Thickening - Resource Book

High Rate Thickeners High rate thickeners are designed specifically to maximise the flocculation efficiency of flocculants. They differ from conventional thickeners in feed well design, size and control. Unlike conventional thickeners, high rate thickeners must use flocculants. The basic design of a high rate thickener is below.

High Rate Thickeners - Solid Liquid Separation

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 machines.

settling, high rate thickening and/or clarifying, high compression and also paste thickening. A feed rate of 1-8m3/h (4.4-35.2 US gpm) of pulp is required for the pilot plant thickener/clarifier. Testing is required for the selection of correct thickener or clarifier size and configuration for each customer’s application.

High Rate Thickeners - Mineral Processing & Metallurgy

They contain space-cutting baffles that intercept settling paths at many levels. Solids settle out onto the baffles and are removed from suspension after settling only a short distance. Where and to the extent that removals are governed by settling rates, such baffles increase the capacity of a space into which they are introduced. They do not increase its volume, so do not increase solids removal where it is governed by flocculation rate and hence by retention time. Thus lamina type units would

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.

High efficiency Thickeners make use of flocculant to help agglomerate very fine particles into larger particles that can settle much faster than the fine particles themselves. All solids settle to the bottom of thickeners and clean water rises to the top so the solids settling rate must always be greater than the clean water rise rate.
