Continuous Thickening Theory

2020-12-1  In a continuous thickener the downward solids velocity with respect to the thickener wall is the sum of the settling velocity of the solids by gravity alone, Vi, plus the downward velocity caused by removal of the thickener underflow, U. The rate at which solids move downward by gravity alone is expressed as the product of the concentration of the solids in a layer, Ci, and the settling

The ANDRITZ TD, a rotary screen thickener, is an excellent alternative to gravity belt thickeners for continuous dewatering of sludge thanks to its small space requirement. Due to the efficient and reliable thickening process and the high hydraulic capacity, the TD can remove up to 90% of the water in the sludge. The compact design results in

Types of Thickeners Xinhai

The thickener is mainly composed of two parts including thickening tank and rake-type mud scraper, and the tank is used to store the slurry while the scraper is used to deal with the settling materials. Thickening equipment developed lately in China.

Rheology Modifiers in Paints and Coatings: Types and

TAGS: Rheology Modifiers As you know, rheology is crucial for the success of your paint at every step: manufacturing, storage and final application. In both solvent-based and waterborne formulations, rheology modifiers (also called thickeners for paints) help to achieve the desired rheological behavior.

How a Thickener Works 911metallurgist

2020-12-9  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

Difference Between Clarifier and Thickener

2020-12-9  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

Thickener an overview ScienceDirect Topics

The thickener was applied at various concentrations (0, 4, 8, or 12 g/l) in the pretreatment bath to determine the effect of cationization on the optimal level of thickener. The concentrations of soda ash and urea in the pre-treatment were 40 and 100 g/l respectively.
