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.

Beginners guide to thickeners - Metso Outotec

Jun 16, 2017  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 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. Furthermore, they are normally positioned far away from the center of the plant so to allow ...

Sizing and Operating Thickeners

Jan 28, 2018  Thickeners are often operated to keep the interface height constant using a level control device or manual measurements of the sludge level. In this case, if the feed solids rate is increased from 10.0 to 11.1 metric tons/day, the operating point at steady-state will move from point no. 1 to point no. 4.

MIP Process Technologies Thickening and Clarification

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.

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).

CHAPTER 3 SLUDGE THICKENING - Marmara Üniversitesi

thickening operations are carried out. Actually, the thickening of the sludge is a concern to the operator where he desires a high underflow solids concentration. So it is the general practice to design these processes for both thickening and clarification performance.

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.

Sep 10, 2015  On the one hand, if the underflow rate is too low, it is possible to make the thickener overloaded and the mineral particle loss when the mud bed level is high enough. On the other hand, if the underflow rate is too high, thickeners will be “short-circuited” when the mud bed is pumped out and the feed is directly discharged.

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.

Controlled Aerobic Digestion of Thickened Sludge ...

Dec 28, 2000  Oxygen Requirements. When thickened sludges are fed to the aerobic digester, the oxygen uptake rate in the first part of the digester is extremely high, with as much as 70% of the total oxygen requirement needed in the first ten days. The aeration system must be designed so that there is enough built-in flexibility to ensure that the oxygen profile in the basin matches the oxygen demand.

High blood pressure causes thickening of the walls of blood vessels and also makes them more likely to develop hardening of the arteries (atherosclerosis).

Other High Rate Clarifiers. In ballasted flocculation clarifiers (e.g. the Actiflo® process) a suspension of fine quartz sand (d 10 of 100–150 μm and uniformity coefficient of 1.6) is used as a ballasting agent to form a weighted floc of density in excess of 2.5 kg/l, resulting in very high settling velocities. In the process coagulant is ...

Feb 08, 2021  The technique is used in the same way in both industrial and municipal settings. A gravity belt thickener employs ‘gravity drainage’ whereby dilute sludge (typically 0.5% to 1.0%) is introduced at the feed-end of a horizontal filter belt. As the slurry makes its way down the moving belt, any free water drains through the porous belt.
