Related Surface Area Calculator | Area Calculator. Volume is the quantification of the three-dimensional space a substance occupies. The SI unit for volume is the cubic meter, or m 3.By convention, the volume of a container is typically its capacity, and how much fluid it is able to hold, rather than the amount of space that the actual container displaces.
The thickener area is also required for this calculation. 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 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).

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.

What is a BTU? The British Thermal Unit, or BTU, is an energy unit. It is approximately the energy needed to heat one pound of water by 1 degree Fahrenheit. 1 BTU = 1,055 joules, 252 calories, 0.293 watt-hour or the energy released by burning one match. 1 watt is approximately 3.412 BTU per hour.
The required depth of the thickener may be ascertained by computing the capacity of the thickening zone to contain a supply of solids equal to the total capacity of the tank for the number of hours required to thicken the pulp to the density required in the discharge, and to this depth adding an allowance for the lost space due to the pitch of ...
– High Capture Rate – Compact Footprint – Little Operator Attention Required – Low Operation and Maintenance Cost . Why Thicken Sludge Thickening Sludge increases digester capacity, reduces hauling costs and can be used as a pre-thickener to increase capacity of other dewatering equipment. Example: 192,000 gallons can be ...
Calc UF: The thickener model calculates the underflow rate required to give the user defined solids fraction. This rate is set by the thickener and the user cannot set the underflow rate. User UF (Qm) This operating mode allows the user to set the thickener underflow mass rate. This is the only option when the model is used in a steady-state ...
Conventional thickener THK, high-rate thickener HR-THK Thickening – Clarification – CCD circuits. Thickeners are used in various solid/liquid separation processes in order to increase the density of a process stream. Feed solids concentration is the single most important variable affecting the sedimentation properties of a given slurry.
Like the High Rate thickener, ... body, the thickener design need s to include adequate rake t orque capacity to handle a high densit y, high viscosity slurry.
Poor solid-liquid separation functions can threaten the overall performance of your processing plant. With our efficient feed dilution and flocculation technology, we provide superior thickening performance in the form of better overflow clarity and higher underflow densities, while minimising your operating expenses.

188.8.131.52 High-Density Thickener (HDT) High-density thickeners are an extension of high-rate thickeners, which utilise a deeper mud bed to enhance the thickening capacity. HDTs usually add depth to a high-rate design to support increasing underflow density.
In the 1970s and 1980s, machines known as High Capacity or High Rate Thickeners were introduced in the mining industry. The distinguish feature of these equipment was that the feed was injected into the sediment bed. EIMCO HI-CAP Thickener (Webpage)High Capacity Thickeners. Enviro-Clear High Capacity CT (Web page).
The thickener or clarifier is the major piece of equipment used to recover water in mineral and industrial processes. The one thing all thickeners have in common, the feedwell, is the core of every thickener's performance. A thickener relies on a feedwell for even distribution of solids and flocculation of suspended particles.
addition. High rate thickeners, as well as de-watering systems that use cyclones only or cyclones and high-rate thickeners can also be used in principle. Leaching reagents in the form of cyanide and an oxidant such as air or oxygen are added after thickening. Leaching takes place in a series of agitated leach reactors or pachucas.
Stirring would not increase the capacity of the thickener beyond the natural capacity for discharging pulp of the consistency at which the channels have just closed; on the contrary, the capacity should be slightly lower, due to the fact that the D in Mr. Mishler's formula No. 3 becomes less and A, or required area, consequently becomes greater.
Online calculator. This article contains online calculators which can calculate discharge times for specified discharge current using battery capacity, the capacity rating (i.e. 20 hour rating, 100 hour rating etc) and Peukert's exponent.
This is normally achieved by using compression (or high rate) thickeners or a combination of thickeners and filter presses. High Density Thickened Tailings (HDTT) are defined as tailings that have been significantly dewatered to a point where they will form a homogeneous non-segregated mass when deposited from the end of a pipe (Welch 2003).

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 ...

In light of this observation, we prefer in general the term "high-rate" instead of "high-capacity" mode. Examples 9–17, shown in Fig. 8, Fig. 9, Fig. 10, are simple examples of charts that can be produced if the information of series of steady-state profiles under continuous variation of parameters is condensed.
