drum thickeners for the separation of solids and liquidsDrum Thickeners

We offer a range of mechanical sludge thickeners or dryers for wastewater treatment and industrial sludge reduction. Drum thickeners are devices for thickening sludge mechanically are used for drying sludge from municipal, industrial and solids wastes. Reduce your sludge volumes by as much as 90% which could mean significant savings when it comes to transporting liquid sludge.

How it works
Drum thickeners work by conveying polyelectrolyte treated (flocculated) sludge through a slowly rotating drum filter. The sludge remains in the drum, while the water phase passes through the filter cloth. Sludge concentration is regulated by adjusting the 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.

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.
  • Their 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.
  • They address new applications through a wide range of filter cloths.

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.
