working of an industrial thickener

EPA 832-F-00-053 - September 2000

Thickening and dewatering systems can result in significant savings in the cost of biosolids storage, transportation, and end use or disposal. Thickening liquid biosolids from three to six percent total solids will reduce the volume by 50 percent. Thickening is often used before anaerobic digestion or lime stabilization to reduce the capital ...

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, resulting in a reduction in flocculants consumption and a more stable operation, with few emergency conditions. Water consumption has become an important issue for the mineral processing industry.

What is the thickener in lubricating grease?

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.

Batch sedimentation, clarifiers - SlideShare

Gravity Thickener Thickening is the process by which bio solids are condensed to produce a concentrated solids products. Thickening wastewater solids reduces the volume of residuals, improves operation, and reduces costs for subsequent storage, processing, transfer, end use, or disposal. Gravity thickening uses the natural tendency of higher ...

Sludge Thickeners ISP- WAMGROUP

The ISP Sludge Thickener increases the concentration of the sludge due to its slow moving arms and vertical pickets. This also enables liberation of gas bubbles and aggregation of flakes of sludge. The system is installed inside a circular tank with a walkway made of concrete. It is mainly composed of a central drive shaft made of steel ...

Difference Between Clarifier and Thickener

CableTorq® thickeners; High rate thickeners; HOW THICKENERS WORK. Feed enters the velocity break box where excess energy is removed from the slurry prior to entering the Thickener feed pipe. Flocculant is added into the feed pipe and mixes with the solids, forming larger agglomerations, that will rapidly settle to the bottom of the Thickener.

Grease Basics - Machinery Lubrication

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.

How a Thickener Works

How a Thickener Works. 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 ...

Choosing the Right Grease Thickening System

Choosing the Right Grease Thickening System. You may ask yourself why the selection of a grease thickener is so important to your application. First, let's define what a grease thickener is. The NLGI grease guide states a thickener is "the solid particles which are relatively uniformly dispersed to form the structure of lubricating grease ...

Lamella clarifier - Wikipedia

Range of applications. Lamella clarifiers can be used in a range of industries, including mining and metal finishing, as well as to treat groundwater, industrial process water and backwash from sand filters. Lamella clarifiers are ideal for applications where the solids loading is variable and the solids sizing is fine. They are more common than conventional clarifiers at many industrial sites ...
