<emphasis role="bold">GRAVITY THICKENER</emphasis>Gravity thickeners function much like settling tanks: solids settle via gravity and compact on the bottom, while water flows up over weirs (see Figure 23.1). They also provide some solids equalization and storage, which may be beneficial to downstream operations.Gravity thickeners work best on primary and lime sludge, but also are effective on primary sludge combined with trickling filter solids, primary and activated sludge, anaerobically digested solids, and to a lesser degree, activated sl…
