Description
Unlike traditional crossflow filtration methods, the Andritz Dynamic Crossflow Filter (DCF) can concentrate the retentate to achieve a pasty or sludge consistency – making it much more effective.
The overlapping ceramic membrane disks rotate in the same direction to create a turbulent crossflow without using a pump to circulate the rentate. The wall shear stress generated is 50% higher than found in conventional crossflow filters – greatly reducing the formation of a clogging layer, while substantially improving the filtration rate at the same time. This advantage is most evident when dealing with high-viscosity retentates.
