APPLICATION OF A SLUDGE GRAVITY THICKENING MODEL

Gravity thickening has long been recognized as an effective unit operation for sludge volume reduction. Such volume reduction greatly enhances the cost effectiveness of subsequent sludge handling techniques. Thickening is also an important phenomenon when considering the performance of secondary clarifiers in the activated sludge process.

HUBER Solutions for Sludge Thickening - HUBER SE

Sludge settles in gravity thickeners and is compressed by the weight of its own solids. Due to their higher specific density, primary and digested sludge can be better gravity-thickened than secondary sludge. Secondary sludge (e.g. waste activated sludge) is preferably thickened mechanically, separate from primary sludge.

Sludge Screening - HUBER SE

Efficiant and reliable sludge screens for removal of disturbing solids (e.g. plastics, hair and fibres) to prevent disruption of subsequent sludge treatment processes and equipment. Reused sludge should not contain any debris. Even where the raw wastewater is fine-screened, some more solids can be removed with our sludge screens.
