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 McNally Sayaji Engineering Ltd.

Our main product offeringis the High Rate Thickener (HRT) which has several special features that provide advantages over conventional thickeners. We can also offer Conventional thickeners, High compression thickeners and clarifiers. The key advantages of a High Rate Thickener over a conventional thickener are as follows:

Thickener EKCP

EIMCO-K.C.P. High rate thickeners are designed to provide high underflow concentration with smaller diameter. The high velocity feed is split to two compartments with opposite tangential inlets that are positioned in two levels, an upper and a lower one. Between those compartments there is a narrow gap through which the flocculent solution is

Sizing and Operating Thickeners

This paper presents a development of thickening theory which provides a reliable and easy-to-use method for determining the size of continuous thickeners from batch settling tests. It also offers a description of thickener operation performance based upon the proposed method. Thickener Operation Figure 13 shows a log-log relationship between underflow concentration and unit area at various

Thickening and clarifying

Thickeners and clarifiers, when properly optimised for performance and operating cost, offer some of the most cost-effective technologies available to meet both of these goals. Technology leaders We bring extensive experience in sedimentation and flocculation technology to your process needs, and can help determine the most cost-effective

Thickeners Solid Liquid Separation

The high time for thickeners was in the 60's when the metallurgical industries were booming and sizes of up to 150 m diameter were constructed. Such jumbo thickeners, when centrally driven, require for most demanding applications extra heavy duty drive heads some of which reach a continuous operating torque of 3.300.000 Nm.

What is the Sludge Thickening Process in Water Treatment

Mar 06, 2018 Thickening tanks have slow-moving vertical paddles. Sludge flows into the thickening tank, and eventually, it removes excess water from the solids collecting at the bottom. A gravity thickener has a similar process to the tanks, but it has a sloped design so that solids collect at the base.

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

The following is a short cut to designing your own thickener: (a) Size of Thickener As a first stab we can either use the thickener flux (m. 2 /tpd) or the rise rate, depending if solids loading is the dominant (eg. Platinum Tailings) or feed flow rate (e.g. Clarification or low feed solids).

Improve Clarifier and Thickener Design and Operation

Guess the thickener area for the first iteration. Several iterations of area may be required to achieve a practical thickener size and pumping rate. For a circular thickener with a 15.24 m (50 f t) dia.: A= Pi r 2 = 182.4 m 2 (7) The applied solids feed rate can now be calculated as a flux see Eqs. 8a and 8b.

used to agglomerate the solids to increase the settling rate and improve the overflow clarity. Thickeners generally operate continuously with very high on-line availability. They are used in a wide variety of industries, and in numerous applications. Thickener control has a number of complexities such as varying feed characteristics. Changes in
