HUBER Solutions for Sludge Thickening Thickening is the first step for reducing the sludge volume by removal of free sludge water Thin sludge is concentrated to thick sludge Thick sludge has a higher viscosity, but must still be pumpable...
PHOENIX Process Equipment Sedimentation thickening uses polymers to agglomerate fine particles, increase the solids settling rate and reduce the size of slurry ponds by immediately returning 75%-80% of the process water as thickener overflow to the wash plant Thickeners, however, cannot totally eliminate the need for slurry ponds...
Wastewater treatment Wastewater treatment - Wastewater treatment - Primary treatment: Primary treatment removes material that will either float or readily settle out by gravity It includes the physical processes of screening, comminution, grit removal, and sedimentation Screens are made of long, closely spaced, narrow metal bars They block floating debris such as wood, rags, and other bulky objects that could ....
Conventional thickener THK Conventional thickener THK ANDRITZ Delkor (Pty) Ltd utilizes modern engineering technologi Thickeners are utilized 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...
High Efficiency Thickener Of Nzsg24 Of Xinhai Efficient Thickener Manufacturer of Efficient Thickener High efficiency thickener is not simple equipment but with a new type of dewatering equipment mud layer filtration characteristics Its main feature is to add a certain amount in the flocculants to be concentrated pulp the pulp of mineral particles form flocks accelerate the sedimentation rate and improve the efficiency of the concentrate...
THE HISTORY OF DORR THE HISTORY OF DORR-OLIVER Dorr-Oliver began at the turn of the 20th century as two one-man operations, backed by single patents for equipment developed to ,...
Wastewater treatment Wastewater treatment - Wastewater treatment - Sludge treatment and disposal: The residue that accumulates in sewage treatment plants is called sludge (or biosolids) Sewage sludge is the solid, semisolid, or slurry residual material that is produced as a by-product of wastewater treatment process This residue is commonly classified as primary and secondary sludge Primary sludge is ....
THICKENERS A thickener is an equipment structure used for the continuous gravity settling (sedimentation) of solids in suspensions Suspension is fed into one or more basins or chambers and, whilst it is passing through, the solids settle out The thickened solids are removed together with a ,...
Lamella clarifier Both the overflow stream and the underflow stream from a lamella clarifier will often require post-treatment The underflow stream is often put through a dewatering process such as a thickener or a belt press filter to increase the density of slurry This is an important post-treatment as the underflow slurry is often not able to be recycled ....
Proper thickener underflow densities The operating principle of a thickener is simple and sound, but in the real world, your thickener may not be providing the best performance Turn to us to produce a design that is best suited to your process application Our thickeners deliver dependability, efficiency and the greatest operational flexibility...
Dynamic simulation of pilot thickener , The phenomenological theory of sedimentation-thickening processes predicts the settling behavior of a flocculated suspension in dependence of two functions, the batch flux density function and the effective solid stress These functions were determined using batch settling tests The governing equations for sedimentation were then solved numerically for these functions and the predictions were ....
Audit industrial thickeners with new on Audit industrial thickeners with new on-line instrumentation , The two constitutive equations, or thickening parameters, describing the sedimentation-consolidation in a thickening operation are the solid flux density function and the solid effective stress...
How to Operate a Thickener How to Operate a Grinding Circuit How to Operate a Flotation Circuit This Robert Ramsey article, now in the Public Domain, is based largely on information furnished by C K McArthur, of The Dorr Co, Inc, New York, N Y, and further information and suggestions were furnished by H L Hazen and Wayne C Hazen, of Manganese Ore Co, Boulder ....
Thickening and clarifying We also have led the way in developing paste thickening technology, with more paste thickening installations than all of our competitors combined All of the durable and productive thickening and clarifying equipment we offer is among the most technologically advanced and rigorously tested products available on the market today...
Sedimentation Testing Sedimentation Sedimentation is defined as a process of separating specifically heavier, suspended matter by gravity settling Solid matter settles on the bottom of the vessel and the liquid above it is poured off The primary purpose of the process is to produce a clarified liqu Figure 1 illustrates the definition Figure 1: Sedimentation ....
Thickener Torque A little earlier I talked about the rakes of the thickener, these are long arms that extend off of the bottom of the DRIVE SHAFT As the shaft turns the rakes will sweep the entire bed of the thickener thereby applied Torque Each rake arm is higher at its far end than it is where it joins the drive shaft This is designed this way to give the bed a slope towards the centre of the thickener ....
Sedimentation Sedimentation is the tendency for particles in suspension to settle out of the fluid in which they are entrained and come to rest against a barrier This is due to their motion through the fluid in response to the forces acting on them: these forces can be due to gravity, ....
Lamella EcoFlow® Lamella Clarifier The Lamella ® is the original inclined plate clarifier Introduced by Parkson in 1971, it has been the industry standard for this technology How It Works The Lamella clarifier works when a solid/liquid stream that has been flocculated, enters a tank, ,...
