Rota-Rake Thickener - Graver

Vertical Pickets With the addition of vertical pickets to the sludge scraper arms, thickening is enhanced. Moving through the sludge layer in the hindered settling zone, the pickets create open spaces in the compacted sludge, allowing water to rise to the top and sludge to fall to the bottom. Thus, maximum dewatering and thickening of the

Sludge treatment − gravity thickening | Sludge Processing

Gravity thickeners generally retain 80−90% of the solids in the thickened product stream, depending on the sludge characteristics and the efficiency of the preceding conditioning stage. The sludge characteristics also govern the solids loading rate (SLR), which is the rate in kg/d at which the sludge dry solids enter the process per unit process cross-sectional area.

Sludge Thickening - an overview | ScienceDirect Topics

Sludge Thickening. Sludge thickening is a process in which the solids concentration is increased and the total sludge volume is correspondingly decreased, but the sludge still behaves like a liquid instead of a solid. Thickening commonly produces sludge solids concentrations in the 3% to 5% range, whereas the point at which sludge begins to ...

Sludge Thickening - an overview | ScienceDirect Topics

With the aid of polyelectrolytes, coagulant sludge can be thickened to concentrations in the range 2–6% w/v solids. The polyelectrolyte dose can be in the range 0.1–1 g/kg of dry solids and the dose should be applied proportional to the feed solids concentration and flow. It should be well mixed using an in-line static mixer or similar.

What is the Sludge Thickening Process in Water …

Thickening tanks have slow-moving vertical paddles. Sludge flows into the thickening tank, and eventually, it removes excess water from the solids collecting at the bottom. A gravity thickener has a similar process to the tanks, but it has a sloped design so that solids collect at the base.

The sludge is sometimes passed through a so-called pre-thickener which de-waters the sludge. Types of pre-thickeners include centrifugal sludge thickeners, rotary drum sludge thickeners and belt filter presses. Dewatered sludge may be incinerated or transported offsite for disposal in a landfill or use as an agricultural soil amendment.
