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.

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.
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. Furthermore, they are normally positioned far away from the center of the plant so to allow ...
So, the thickener side wall depth (H) is calculated as :- H = h1 + h2 + h3 + h4 The depth at the center of the thickener is calculated by adding (H) to h5:-, . 16 h5 d thickenerdiameter d To calculate (h4), the thickening zone height, we assume that this zone has a volume enough to store one day thickened sludge. So the total solids

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
Dec 28, 2000· When thickening waste activated sludges mechanically, it is usually possible to achieve greater than 7% to 8% solids. However, if this is fed continuously to the aerobic digester, then it is likely that any aeration system will have difficulty meeting the oxygen demand given the viscosity and high …
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.

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:
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 ...
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.
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 ...
High Rate Thickeners Perhaps the most significant design optimisation effort in thickening in the last twenty years has been in developing ways to more effectively use the horizontal cross sectional area of the thickener. The introduction of polymeric flocculants gave an impetus to development of High Rate Thickeners.
