ALDEC G3
Alfa Laval ALDEC G3 decanter centrifuges are the latest generation of sludge dewatering equipment for municipal and industrial wastewater treatment plants, designed to set a significantly higher standard for both process performance and environmental impact in sludge thickening and dewatering applications.
Ground-breaking decanter setting new heights for performance:
- Lower power consumption (which also greatly reduces CO2 emissions)
- 10% boost in processing capacity – or drier cake
- Reductions in life cycle costs
- More efficient bio-solids handling
- Better process monitoring and control
A set of innovative parameters
Alfa Laval unparalleled decanter centrifuge technology has paved the way for a series of ground-breaking innovations, all based on proven technology renowned for reliability. Together, these ensure a unique combination of better performance and lower energy consumption, resulting in lower operating costs than ever before.
The ALDEC G3 decanter is built around the Slimline design – a breakthrough in decanter centrifuge performance and capabilities. The smaller conveyor diameter makes room for more liquid in the pond, and allows higher bowl wall pressures, resulting in either drier cake or using less polymer.
Patented Alfa Laval Power Plates also effectively reduce the power consumption of ALDEC G3 decanter centrifuges, making a big contribution to cost savings.
Every ALDEC G3 decanter is equipped with a PLUS control package as standard, pre-installed and tested in conjunction with each particular unit. The combination of PLUS controls with the ALDEC G3 ensures the best possible performance, keeping costs for installation, commissioning, operation and maintenance to a minimum.
Sludge dewatering centrifuge - feature highlights
- Power plates/tubes and slimline conveyor design
- Critical components made of wear-resistant material
- Fully open feed zone for improved separation 360° solids discharge to avoid blocking
- Baffle disc provides higher capacity and drier cake solids
- Steep or shallow cone configuration for effective separation of any type of slurry
- Selection of conveyor designs available for use with different types of slurry
- Different forms of wear protection for conveyor flights, to suit any processing requirements
- Complete, fully enclosed cleaning-in-place (CIP)
How it works
Separation takes place in a horizontal cylindrical bowl equipped with a screw conveyor. The feed enters the bowl through a stationary inlet tube and is accelerated smoothly by an inlet distributor. The centrifugal force that results from the rotation then causes sedimentation of the solids on the wall of the bowl.
The conveyor rotates in the same direction as the bowl, but slightly slower, thus moving the solids towards the conical end of the bowl. The cake leaves the bowl through the solids discharge openings into the casing. Separation takes place throughout the entire length of the cylindrical part of the bowl, and the clarified liquid leaves the bowl by flowing over power tubes into the casing.
