Sludge Thickening an overview ScienceDirect Topics

So called swirl separators an example of which is illustrated in Figure 7 98 are devices that use a relatively low centrifugal force to separate grit The source of energy for these devices is normally a pump The pump causes wastewater to flow through the swirl separator at a velocity sufficient to cause grit or other high specific gravity material to be thrown to the outside of the

Difference Between Clarifier and Thickener

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

Conventional Thickeners Solid Liquid Separation

Conventional Thickeners are generally incorporated in heavy duty applications when the underflow density is high and substantial torques are required to convey the settled solids from the periphery to the central outlet for pumping away Likewise thickeners are often used for storage to facilitate the continuous feeding of downstream filters
