Volume Calculator

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.

BTU Calculator

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.

Measuring Settling Rates and Calculating Thickener Capacity

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 ...

Thickener 2 - SysCAD Documentation

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 ...

Thickener, Filter press, Hyperbaric disc filter

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.

Machine Rate - an overview | ScienceDirect Topics 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).

EvenFlo™ Feedwell - WesTech Engineering, Inc.

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.

Calculate a Settling Tank's Capacity - Thickener

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.
