ALDEC
Alfa Laval ALDEC decanters bring high separation efficiency, reliable operation and low operating costs to all types of water and wastewater treatment plants. ALDEC is Alfa Laval’s medium range of decanters for wastewater treatment, comprised of a wide variety of sizes. Low power and polymer consumption in combination with easy service makes ALDEC very attractive in terms of total cost of ownership.
ALDEC is available with capacities from 3 to 125 m3/h.
Decanter for wastewater - benefits
- High separation performance
- Low power consumption
- Highly reliable operation
- Upgradable to G3 or G3 VecFlow™
- Replaceable wear protection tiles
- PowerTubes
- Easy to service
Limitations
- Higher Power consumption than ALDEC G3 and ALDEC G3 VecFlow™
ALDEC G3
The Alfa Laval ALDEC G3 features the same technology as ALDEC G3 VecFlow™, except for the feed zone. ALDEC G3 has a standard feed zone, giving it somewhat lower performance and higher power consumption. It is a good fit for a wide range of applications where high separation performance and low power consumption are required, but where the extra benefits offered by VecFlow™ are not necessary. An Alfa Laval ALDEC G3 can be upgraded to the VecFlow™ design.
ALDEC G3 is available with capacities from 23 to 225 m3/h.
Decanter for wastewater - benefits
- Ideal for demanding sludges with high solids loading
- High separation performance, 1% drier solids compared to standard decanters
- Low power consumption
- Upgradeable to G3 VecFlow™ PowerTubes, Slimline conveyor and Direct Drive gearbox
- Replaceable wear protection tiles
- Advanced control system Easy to service
- Available in many materials, including Duplex
ALDEC G3 VecFlow™
Alfa Laval ALDEC G3 VecFlow™ is a state-of-the-art decanter for dewatering and thickening applications. It offers an ideal solution for duties where maximum separation performance, lowest possible power consumption, very high capacity and advanced control possibilities are required. ALDEC G3 VecFlow™ features the most advanced technology available on the market, including our unique VecFlow™ feed zone and Slimline conveyor.
ALDEC G3 VecFlow™ is available with capacities from 23 to 230 m3/h.
Decanter for wastewater - benefits
- Highest performance at the lowest operating cost
