Gravity belt thickening (GBT) thickens sludge by allowing the water (or filtrate) to drain from the sludge under gravity through a permeable medium (a recirculating conveyor belt) on which the sludge sits. The sludge solids concentration is increased along the length of a porous belt as water drains through it, the sludge solids forming a layer

Jun 18, 2020 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

The Gravity Belt Thickener is used to thicken sludge prior to centrifuge or digestion processes. A mix of primary or secondary sludge can easily be thickened to +7% wt, pure secondary to over 5%. The GBT offers: • High unit capacity per floor space • Low residence time eliminates septicity and float scum • Superior thickening • Low

Jun 18, 2020 A rotary drum thickener (RDT) is based on the same principle as a gravity belt thickener (GBT), in that water drains from the sludge through a retaining porous medium. For an RDT the porous medium is the cylindrical wall of a 0.5−1.5 m diameter drum which rotates at speeds between 5 and 20 RPM while the sludge continually passes through it

The Belt Thickener is designed for low polymer consumption, high throughput rates, and high solids content and is available in six standard sizes. Application The Alfa Laval AS-H Belt Thickener is a gravity belt thickener used to thicken dilute sludge and slurries particularly those from biological and activated sludge processes. It is suitable

Gravity belt thickener – GBT The OMEGA Gravity Belt Thickener is designed for the continuous mechanical thickening of municipal or industrial sludge. This simple and efficient technology aims at reducing the sludge volume at least 6 to 7 times according to sludge characteristics. Low energy consumption, Construction stainless steel as as

Gravity belt thickeners are a very cost effective means of thickening sludge. The simplicity of the gravity belt thickening equipment & machinery makes it easy to maintain and its low power consumption makes it inexpensive to operate. Compositech's GT series of gravity belt thickening equipment, also known as gravity belt thickeners, are

The Gravity Belt Thickener is a highly effective tool for dewatering. It operates quietly at a minimal cost, consuming a low volume of wash water. Sludge is flocculated by the use of polymers, introduced on the belt and the released water is drained through the gravity belt. The process is simple, the decrease in sludge volume is impressive
