HUBER Solutions for Sludge Thickening - Huber Technology Inc.

Thickening is the first step for reducing the sludge volume by removal of free sludge water. Thin sludge is concentrated to thick sludge. Thick sludge has a higher viscosity, but must still be pumpable. Sludge settles in gravity thickeners and is compressed by the weight of its own solids. Due to their higher specific density, primary and ...

Sludge Thickeners The HEI Sludge Thickener is an efficient method to gravity concentrate and decant waste sludge. Liquid sludge pumped from a clarifier will have a solids content of 0.5% from cone bottom clarifiers to 2%-4% from the rake bottom clarifiers. The sludge thickener must have sufficient capacity to accumulate and thicken the sludge between filter press cycles.

The thickener area is also required for this calculation. Guess the thickener area for the first iteration. Several iterations of area may be required to achieve a practical thickener size and pumping rate. For a circular thickener with a 15.24 m (50 f t) dia.: A= Pi r 2 = 182.4 m 2 (7)

Sludge treatment − gravity thickening | Sludge Processing

Gravity thickening increases the solids concentration by allowing the particles to settle to the base of a vessel, producing a concentrated (thickened) solids stream at the vessel base and a supernatant (diluted) stream at the surface. Sedimentation, or settling, is the simplest of the thickening processes.

High Rate Thickeners - Solid Liquid Separation

Description The High-Rate thickeners became popular in the mid 1980's and are relatively newcomers to the sedimentation line of equipment. As already discussed previously Thickeners are a major component in a plant layout and occupy large spaces which may be saved by introducing high-rate machines.

Sludge treatment − rotary drum thickening | Sludge Processing

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.
