drum thickeners for the separation of solids and liquids Drum Thickeners

Drum thickeners is a device, which thickens sludge mechanically. It is used for drying sludge from municipal, industrial and solids wastes.

Working Principle:
The drum thickener conveys flocculated sludge through a slowly rotating drum filter. The flocculation is achieved by treating the solid with polyelectrolyte. The water phase passes through the filter cloth leaving the sludge in the drum. Sludge concentration is regulated by adjusting the following:

Feed Rate
Angle and Speed of the Drum

Aldrum Sludge Thickening System
These drum thickeners have a drum cleaning system with a spray bar for water. Using either potable water, final effluent or treated filtrate intermittently, the water consumption is kept low.

ALDRUM comes in four sizes. These are available either as separate components or as complete modules. The ALDRUM Drum Thickener is usually with an ALDRUM Flocculation Reactor.

Aldrum Flocculation Reactors
These are a range of pressure-less reactors with a specially designed agitator to ensure proper flocculation of the sludge. The special design enables the flocculation of the solids in the sludge. The reactors are available in five sizes ranging from 30 GPM to 530 GPM on the basis of 1% dry solids sludge feed.

Aldry High Performance Drum Drying Modules
ADLRY is based on proven technology developed over extensive research work over the years. The modules are factory assembled and pre-tested for quick installation and commissioning. The system uses the direct drying principle with rotating drum and gas recirculation.

What's special about our DRUM THICKENERS?
Alfa Laval DRUM THICKENERS have:
Wide versatility as it can be adjusted to suit individual drum thickening needs. By varying the feed rate, polymer type and dosage etc., optimal thickening is achieved.

Our design addresses critical variables such as: flocculation mixer speed, drum speed, angle of the drum and spraying interval to provide an efficient and economical solution.

drum thickeners for the separation of solids and liquidsWe address new applications through a wide range of filter cloths available from Alfa Laval.

The ALDRY system incorporates:
Safe processes with no accumulation of dust and volatile components.
Low fuel consumption and a wide choice of alternate fuels
Unmanned service for long service intervals
Special ENHANCEMENT packages are available to justify local conditions
