Gravity Belt Thickeners . Brochure. 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.
Paste Thickeners can help producers eliminate the need for settling ponds and other structures. They are meant to achieve the highest solids concentrations possible through gravity separation. The resulting mud, described as a paste, is often so thick that it becomes non-segregating — no further separation of water and solids can be achieved. As a guide, a paste material is measured with a ...
Thickening is the first, and frequently inevitable, step in reducing the volume of sludge extracted from the water line. In fact, it is used to optimise the subsequent conditioning, stabilisation and dewatering stages by reducing structure sizes and operating costs.
The Float-Treat® DAF thickener provides superior performance for solids concentration of water and wastewater sludge. Unlike a gravity belt thickener or centrifuge, a Float-Treat thickener provides grit removal and does not require polymer use.
Sludge is usually pumped continuously from the settling tank to the thickener which has a low overflow rate so that the excess water overflows and the sludge solids concentrate in the bottom. A blanket of sludge is maintained by controlled removal which may be continuous at a low rate.

The Slurry Silo is a cost effective no-nonsense tool for cleaning up water used in the concrete, pre-cast, stone and granite industries. Our proprietary steep cone design is uniquely qualified to deal with heavier slurries from water to maximize the sludge thickening process.
As the sludge compresses/thickens toward the center of the thickener and along the thickener's compressing edge, water passes up into the clarifier at the thickeners ends and at its rising edge. In a vertical sludge rake, the only path for the escaping water is up through the developing sludge blanket, elevating the sludge blanket and slowing ...
The Most Efficient Solution to Thicken Sludge. The Centrisys Sludge Thickener (THK Series) is specifically engineered to achieve high-performance thickening of biosolids. The non-conical design results in greater G-volume, allowing for the highest capacity of flow to the centrifuge.
Nov 16, 2016· The PowerDrum (PDR) is considered to be an easy and efficient thickening solution prior to the dewatering process and can deal with biological sludge throughputs ranging from 15 to 180 m3/hr.

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 ...
The thickeners must be preceded by flow balancing tanks to contain and mix intermittent sludge discharges and feed the thickeners at a consistent concentration and uniform rate (Fig. 13.1). In applications where used washwater (without settlement) is mixed with clarifier sludge, the sizing of the flow balancing tanks becomes critical because of ...

Wastewater treatment - Wastewater treatment - Sludge treatment and disposal: The residue that accumulates in sewage treatment plants is called sludge (or biosolids). Sewage sludge is the solid, semisolid, or slurry residual material that is produced as a by-product of wastewater treatment processes. This residue is commonly classified as primary and secondary sludge.

Thickening/Clarification. Treated water flows to a thickener for sludge thickening and clarification of the water. The metal precipitates as sludge, and a portion of the sludge is recycled to the sludge densification tank. The remainder of the sludge goes to disposal.
The diagram at the left shows a typical flow pattern for a conventional activated sludge aeration tank and secondary clarifier. Some of the parameters that are typically used in activated sludge aeration tank design calculations are shown for the primary effluent, secondary effluent, waste activated sludge, and recycle activated sludge. The following list shows those parameters, along with ...
