Graz -- International technology Group ANDRITZ presents a new generation of weir plates, providing a significant reduction in power consumption for centrifuges. The patented TurboJet weir plate, available for all ANDRITZ decanters and those of other suppliers, helps customers to reduce their energy consumption by 10- 30%.

This innovative product was developed in the ANDRITZ Separation Center of Competence in Châteauroux, France, and passed extensive testing on various customers’ sites, e.g. for waste water treatment, bioethanol production, calcium carbonate separation, as well as in the food and chemical industries. The TurboJet weir plate guides the liquid discharge from the centrifuge in the opposite direction to the bowl rotation. Adjustable nozzles form a jet that creates a reaction force in the same way as a jet engine’s exhaust and recovers the kinetic energy from the liquid. This extra force enhances bowl rotation and thereby reduces main drive power consumption without affecting actual separation performance. Power savings vary depending on feed flow, pond depth, and bowl speed.
