Sludge Dewatering Gravity Belt Thickener Design Solid Liquid Separation

Gravity Belt Thickening for Solid and Liquid Separation of Industrial Processing DHBT-3000

How Gravity Belt Thickening Works:

Gravity belt thickening (GBT) increases the sludge solids concentration (i.e. thickens the sludge) by allowing the water (or filtrate) to drain from the sludge under gravity through a permeable medium (a moving belt) on which the sludge sits.

There are two types of belt-based processes for increasing sludge solids concentration. GBT is a low-pressure process that operates by allowing the water to drain from the sludge under gravity. A belt filter press, on the other hand, operates by squeezing water from the sludge under pressure and achieves a higher dry solids concentration as a result.

In GBT, the sludge solids concentration is increased along the length of a porous belt as water drains through it, the sludge solids forming a layer on the belt surface. The belt is continuously recirculated, as with a classical conveyor belt, and the thickened solids are allowed to fall off the end into a collector vessel – often assisted by a scraper. The filtrate is collected in a sump.

Application:

Sludge Disposal: Belt filter-type thickeners produce sludge cakes with a higher solids content, making them suitable for various sludge disposal methods. The thickened and dewatered sludge can be incinerated, landfilled, or used as a soil amendment or fertilizer, depending on the specific regulations and requirements of the sewage plant and local authorities.

Mining and Mineral Processing: In mining and mineral processing operations, GBT is utilized for the thickening and dewatering of tailings, which are the waste materials remaining after the extraction of desired minerals. GBT aids in separating the solids from the wastewater, allowing for efficient disposal or further processing of the thickened tailings.
