ALDEC G2
Smart Decanter
Shifting the benchmarks
The innovative Alfa Laval ALDEC G2 decanter centrifuge
design has shifted the accepted benchmarks for dewatering
performance, providing an improvement of as much as 30%
compared with previous generations of decanter centrifuges.
This complete range features a compact, modular design
with all critical parts made of wear-resistant materials. The
result is reliable, continuous operation and easy, trouble-free
process control.
Easy to operate, easy to get results
The outstanding features of the ALDEC G2 design make it
easy to accomplish a wide range of performance targets.
• More sludge treated, more efficiently
• Greater processing capacity for any given equipment footprint
• Better process control
• High level of protection against erosion
• Low maintenance costs
• Low energy consumption
• Low life cycle costs
• Major savings on sludge disposal
Enhancement packages
In some cases, the economics of sludge treatment operation
can require the addition of one or more special Alfa Laval
enhancement packages. You can select between:
• enhanced dewatering package – achieve even greater cake
dryness and lower sludge disposal costs.
• enhanced wear protection package – maintenance costs
can be reduced still further by selecting more wear resistant
materials. This in turn extends service intervals.
• enhanced serviceability package – features that save you
time by making both operation and maintenance easier.
• enhanced control packages – add-on control systems that
provide additional functionality and varying degrees of
automation.
