(2004). However, mathematical models are useless if experimental parameters de ning the constitutive equations are not available.
Thickening or dewatering may be defined as the removal of a portion of the liquid from a pulp or slime made up of a mixture of finely divided solids and liquids. The early methods of thickening employed plain, flat-bottomed tanks into which the pulp was fed until the tank was full. The solids were then allowed to settle as long as required, the top liquid was decanted, the settled solids were
Many thickener installations operate with water recovery below design limits largely through conservative control and low prioritization of thickener optimization. The operation of the thickener must accommodate fluctuations control for disturbances in the process feed stream to deliver a clear overflow and thickened underflow.
Thickeners. Monroe Environmental Circular Thickeners are a crucial step between upstream process clarifiers/separators and downstream de-watering and sludge conditioning processes. A well designed thickener provides storage and equalization, and reduces the costs associated with de-watering.
At that time I was employed by Eimco in Salt Lake City, Utah and participated in a team that conducted test work checking the suitability of large diameter thickeners for both concentrate and tailings of the reprocessed ore. The picture on the right shows a 6 meter diameter wooden tank "Dorr" thickener installed back in 1908 in the Kennicott
A thickening agent or thickener is a substance which can increase the viscosity of a liquid without substantially changing its other properties. Edible thickeners are commonly used to thicken sauces, soups, and puddings without altering their taste; thickeners are also used in paints, inks, explosives, and cosmetics.. Thickeners may also improve the suspension of other ingredients or emulsions
A lamella clarifier or inclined plate settler (IPS) is a type of settler designed to remove Particulates from liquids.. They are often employed in primary water treatment in place of conventional settling tanks.They are used in Industrial water treatment.Unlike conventional clarifiers they use a series of inclined plates. These inclined plates provide a large effective settling area for a
industrial, chemical, water treatment and waste water industries. The reliability and performance of DELKOR thickeners means that they are well represented throughout the world. With a wealth of experience and a large database of test work and commissioning, DELKOR can provide accurate estimates on sizing of a thickener for most applications.
Thickeners: How they Operate. The most common solids-liquid (S/L) unit operation is thickening. A wide variety of thickeners are used including conventional, deep well, paste, high rate and clarifiers which is a thickener subclass used for removing solids from turbid or very low % solids waters.
Mar 06, 2018· Sludge contains biosolids that have been removed from liquid sewage. Sludge thickening is the process used in wastewater treatment centers to increase the solids concentration and decrease free water. This step minimizes the load on sludge dewatering and digestion.
activity. A well operated thickener will have a solids recovery of about 95% [3]. Design of Thickeners The thickening process takes place in a settling tank with long-enough solids retention time. For example in secondary clarifiers of activated sludge systems both clarification and thickening
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
Gravity Thickening Method relying on gravity principle can be applied to both untreated primary and even waste activated sludge. It is normally done in a circular tank similar in design compared with a typical plant sedimentation tank.Flow of sludge coming from the aeration system is directed to the center well and the design is such that there is sufficient detention time enough for good
The selection of equipment depends largely on test work for determining the class type. As a rough guideline Class #1 slurries may suit Lamella Settlers, Class #2 Clarifiers handling flocculated slurries and Class #3 Conventional Thickeners.
Many thickener installations operate with water recovery below design limits largely through conservative control and low prioritization of thickener optimization. The operation of the thickener must accommodate fluctuations control for disturbances in the process feed stream to deliver a clear overflow and thickened underflow.
A Critical Review of Thickener Design Methods t F. Concha and A. Barrientos Department of Metallurgical Engineering University of Concepcion* Abstract In this work we analyze, in the light of their physical foundation, the different methods of thickener design that have been proposed in the literature.
Grease consistency depends on the type and amount of thickener used and the viscosity of its base oil. A grease's consistency is its resistance to deformation by an applied force. The measure of consistency is called penetration. Penetration depends on whether the consistency has been altered by handling or working.

With a wealth of experience and a large database of test work and commissioning, DELKOR can provide accurate estimates on sizing of a thickener for most applications.
The Difference Between a Clarifier and a Thickener is subtle as they will visually look the same. Fundamentally, thickeners and clarifiers are both used to settle solids which results in the separation of liquids and solids. Thickeners are used to concentrate solids, while clarifiers are used to purify liquids. A thickener will give you a high density underflow while a clarifier will not. The
Jan 26, 2017· The thickener in a lubricating grease is the component that sets grease apart from fluid lubricants. Thickeners are molecules, polymers, or particles that are partially soluble in lubricating fluid; they arrange themselves in such a way that they impart a semi-solid consistency to the grease.
Apr 01, 2020· It is used for its thickening and stabilizing properties in the food industry along with feed and the industrial industry. Just like the above suggestions, guar gum is also low in calories and is mainly composed of soluble fiber which absorbs water and that how it affects the viscosity and thickens the liquid. Where does it work best?
The sludge concentration achieved in the thickener is independent of the feed concentration. However, the greater the feed volume, the larger the thickener required. There are several thickener designs in use; most are of the settlement type developed for industrial applications, which uses heavy duty scrapers with a picket fence attachment.
Analysis of a range of industrial thickeners from the processing of gold ores, Recent work (Gladman et al., 2005) shows that it is the role of very low shear processes in both the settling .
Sludge thickening using centrifugal force is one of the common processes that can be applied to reduce the water content and thus thickens the sludge. There are basically two different types of centrifuge designed for the application and both methods rely on the same principal to
This work presents an intelligent control based on an expert system applied to an industrial 125 m diameter thickener, processing 13000 m3/h of concentrate containing a 27 % of solids. Main results are a reduction in flocculants consumption and a more stable operation, with few emergency conditions.
