The belt filter press is a kind of thickener for sludge handling system. It is a sludge dehydrator that transforms the processed sludge from low consistency to high consistency. Sludge is gradually dehydrated in different areas by means of gravity dewatering, wedge dewatering, swing dewatering, cut dewatering and other methods. Finally, dry sludge could be obtained. The whole process could be ...
A belt press for use in removing water from sewage sludge, and including a frame, a pair of belts for compressing sludge material therebetween, the said belts being waterpermeable whereby water in said sludge may drain through said belts, and a gravity belt thickener adjacent the belt press. The gravity belt thickener includes a belt having a belt flight adapted to support sewage sludge ...
· How gravity belt thickening works. Gravity belt thickening (GBT) increases the sludge solids concentration ( 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 beltbased processes for increasing sludge solids concentration.

Sludge Treatment Equipment. BELT FILTER PRESS. Designed for continuous mechanical dewatering of municipal and industrial sludge. GRAVITY BELT THICKENER. Designed for continuous mechanical thickening of municipal or industrial sludge. COMBO GBT + BFP. Associates the functions of one gravity belt thickener and one belt filter press.
A gravity belt thickener employs 'gravity drainage', dilute sludge (typically % to %), which is introduced at the feedend of a horizontal filter belt. As the slurry makes its way down the moving belt, any free water drains through the porous belt. The solids are continuously turned, encouraging the drainage of more water through a filter belt to thicken. A drum thickener works ...
An independent gravity zone has the same capability as a standalone gravity belt thickener and, therefore, has appliion on a dilute sludge where the suspended solids are less than %. Further, a Belt Filter Press may be designed as a combination thickening unit/dewatering unit. In the thickening mode, a doctor blade is engaged at the discharge roll to remove thickened solids from the ...
While using the gravity thickener for sludge thickening,the belt filter press also employs the upper and lower belts which work for further gravity entrained water will be eliminated to a large extent as the material moves through the gravity zone that is 6 to 11 meters long.
· Gravity thickening is the process by which biosolids are condensed to produce a concentrated solids product and a relatively solidsfree supernatant.

Try backing down on your floc dosing a bit. As I see it if your filter belts/cloths are getting blinded there is an overdose issue as in normal situations the floc does not blind the cloths. I would think your thickener would give you some indiion of what is happening with the floc. Being a lead operator you would probably already thought of ...
08/03/2016 · Standard thickener depths are as follows: Storage Capacity: Another factor to be considered is the storage capacity desired in a thickener. For example, it may be necessary to shut a filter down for repairs and at the same time keep the balance of the mill in operation. In this case the thickener will act as a storage reservoir. Where storage ...

How Gravity Belt Thickeners Work. Compositech's gravity belt thickening equipment employs the forces of gravity for filtration in order to allow liquid to drain from the sludge through a single woven cloth filter belt. Initially, the liquid sludge is conditioned by adding polymers to obtain a separation between the liquid phase and the solid phase.
