Advantages of gravity sludge thickener design

chapter 3 sludge thickening marmara 220;niversitesidesign of thickeners the thickening process takes place in a settling tank with longenough solids retention time. for example in secondary clarifiers of activated sludge systems both clarification and thickening operations are carried out. actually, the thickening of the sludge is a concern to

wastewater treatment sludge treatment and disposal thickening is usually the first step in sludge treatment because it is impractical to handle thin sludge, a slurry of solids suspended in water. thickening is usually accomplished in a tank called a gravity thickener. a thickener can reduce the total volume of sludge to less than half the original volume.

improve clarifier and thickener design and operationclarifiers and thickeners are essentially ide ntical units; a clarifier produces clean water, while a thickener concentrates a solids slurry as the desired product. in this discussion, thickener will be used to describe both units. also, a gravity separation of solids from water is assumed to take place.

gravity belt thickener komlinesandersona gravity belt thickener employs gravity drainage through a filter belt to thicken polymer conditioned sludge prior to digestion, mechanical dewatering, or trucking to a land application site or disposal site. dilute sludge (typically 0.5% to 1.0%) is introduced at the feed end of a horizontal filter belt.
