ALDEC
Alfa Laval Aldec decanter centrifuges are designed for the sludge thickening and dewatering process in municipal and industrial wastewater treatment plants, with a focus on cost-efficiency, reliability, easy operation and sustainability.
Benefits of using the Aldec for sludge treatment
- Reduces sludge volume during the sludge thickening and dewatering process, which cuts down on transport and disposal costs
- High capacity at small footprint: Compact, modular design saves space
- High performance combined with low energy consumption
- Wear-resistant design with anti-blocking feature.
- Complete, fully enclosed cleaning-in-place (CIP)
The extensive range of Aldec centrifuges for sludge thickening and dewatering are capable of handling a wide range of flow rates. They are designed to be efficient, simple to install, easy to maintain and straightforward to operate. Installation, operating and service life costs are minimal.
Sludge thickening and dewatering - Less water, lower cost
Cost-effective sludge decanter centrifuges are crucial for removing the water content from sludge from wastewater plants, as well as from industrial waste streams. The drier the sludge, the less space it takes up and the less it weighs – both resulting in big savings on transport and disposal costs, whilst helping to meet sustainability requirements.
Low energy consumption and labour costs
When using the Aldec decanter centrifuges in your sludge thickening and dewatering process, you benefit from low energy consumption as well as a minimum of maintenance costs, keeping dewatering costs to a minimum. They are also fully automatic, so you can keep labour costs down.
How it works
Separation occurs in a horizontal cylindrical bowl with a slimline screw conveyor. The feed enters through a stationary inlet tube and is smoothly accelerated by an inlet distributor in the feed zone. Centrifugal force causes solids to sediment on the bowl wall. The conveyor, rotating slightly slower than the bowl, moves solids to the conical end. The cake exits through discharge openings into the casing. Separation takes place along the entire cylindrical bowl, and the clarified liquid exits through adjustable outlet tubes.
