They are available in shaft or cage driven models. Shaft drive thickeners can be truss or beam supported for heavy duty applications. A heavy duty drive unit with precision bearing and gear ...
The shaftless screw, operating at pre-set water levels, brushes the captured solids from the screen surface and moves them up the transport section, to a zone where a plug is formed. Solids are dewatered by compaction against the plug and liquid is discharged through a short slotted screen section.
Thickening is usually accomplished in a tank called a gravity thickener. A thickener can reduce the total volume of sludge to less than half the original volume. ... This zone is compaction zone. The most commonly used thickening processes include gravity thickening, dissolved air flotation, and rotary drum thickening. Centrifuge thickening is ...

The drum rotates in the direction of the incoming feed, carrying the pulp underneath the drum to a compaction zone on the other side where dewatering occurs. Filtrate passes through the perforated deck and is discharged ...
This zone is the compaction zone. The most commonly used thickening processes include gravity thickening, dissolved air flotation, ... Gravity Thickener. A gravity thickener is much like a clarifier in that the sludge/water mixture enters through the center in the influent line. This reduces the hydraulic force of water and sludge that enters ...

The rakes convey underflow sludge to the discharge point and thicken the sludge by creating paths in the compressed zone, which allows escape of entrapped liquid upwards. The characteristic features of a High Rate Thickener, which distinguishes it from a Conventional Thickener, are: Deeper feedwell; De-aeration of the feed (either
a DAF or centrifuge thickener. Belt thickeners may produce supernatant with lower solids concentrations depending on the equipment and solids characteristics. • More land area is needed for gravity thickener equipment than for a DAF, gravity belt, or centrifuge thickener. • Solids concentrations in the thickened solids are usually lower ...
zone B appears to transition directly onto zone D. If the thickener is fed indefinitely under dynamic batch mode conditions, the mud bed interface will rise ... zone D undergoes compaction from the moment of its formation due to the accumulation of solids mass above it. Consequently, the longer the sediment is allowed to accumulate within the ...

A thickener operates pretty much like a settling tank. The feed enters from the middle, are distributed radially, the settled sludge is collected from the underflow, the effluent exits over the s. ... This zone is compaction zone. Sludge blanket is defined as the top of the feed zone. The height of this blanket is the main
The settling zone is where the separation of solids from the liquid occurs within the thickener. Design considerations for the settling zone include the tank diameter, depth, and slope of the tank floor. A larger settling zone with an appropriate floor slope allows for effective settling of solids, resulting in improved thickening efficiency.
Formation of 3D network structure through adsorption of polymer thickener; The thickening mechanism is explained by the formation of a hydrogen bond between a carboxyl group and a water molecule, known as hydration by the carboxylic acid moiety.
