Compact Structure Gravity Sludge Thickener Totally Enclosed Robust Design
Product Introduction of KDS Sludge Thickening Machine
Thickening is often the first step in a sludge treatment process. Sludge from primary or secondary clarifiers may be stirred form larger, more rapidly settling aggregates. Function of gravity thickeners are very similar to settling tanks. Solids settle via gravity and compact on the bottom, whereas water flows up over lashers. Gravity thickeners also provide some solids stabilization and storage, which may be beneficial to downstream operations. Smooth up-flow weir design provides uniform distribution of slurry across the entire width of the belt. A large filtration area provides high efficiency thickening and cost-effective chemical utilization.

Working Principle
The sludge thickener works on the principle of separating liquid from solids by gravity drainage through a slowly rolling belt cloth. It uses a sludge polymer mixing valve with an adjustable lever arm to ensure sufficient turbulent sludge/polymer mixing.
After this, the ramp feeding section delivers a consistent load across the filtration area to maximize filtration properties.
A sludge retention tank, also known as the flocculation chamber, is filled from the bottom and then rises up over a weir to ensure even distribution onto the belt. Sludge ploughs force the sludge into lanes, which allows free water to run through the belt cloth where sludge is not present, thus enhancing the pre-dewatering process. Sludge ploughs can be lifted to allow for removal of rags etc.
The result is excellent thickening in a totally-enclosed, low-odour unit.
Sludge Thickening And Dewatering Machine Advantages
1. Reduce the volume of sludge, thereby reducing waste disposal cost
2. Low energy use and polymer consumption
3. Lower labour cost and cost of change, thanks to minimal need for operator attention and maintenance
4. Totally-enclosed, low-odour unit with easy access for better safety and work environment
5. Robust design avoids fatigue and wearing
