Recovery of high value streams by separating solids from liquids and liquids from liquids with dissimilar densities.
The ANDRITZ decanter centrifuges A are basic solid bowl decanter centrifuges to which features can be added for special applications. The solid bowl is ideal for clarification of liquids, thickening of sludges, and separation of solids
Constant separation results, even at fluctuations in the volumetric flow, the process conditions, or the product characteristics
Materials such as titanium, pure nickel, or Hastelloy provide the security essential in demanding process applications.
Liquid phases of differing densities can also be separated.
For the chemical industry, we provide
clarifiers, separators, and concentrators for
liquid/liquid, liquid/solid and liquid/liquid/
solid separation. These units are suitable
for a wide range of applications, including:
industrial fermentation processes
the biotechnology industry
the biofuel industry
the petrochemical industry
In this technology, overlapping, rotating discs generate a differential speed in relation to one another. This design creates a turbulent crossflow without using a pump to circulate the slurry. By applying wall shear stress that is at least 50% higher than in conventional crossflow systems, the formation of a clogging layer, which obstructs the permeate flow, can be avoided or at least reduced significantly. Ceramic filter membranes are installed as standard, but metal filter membranes can also be installed. Upgrades for existing plants, with a DCF being included downstream of a traditional crossflow filter, enhance the process, reduce energy costs, and increase the throughput. In any event, removal of bottlenecks is often the main reason for installing a DCF, and in some cases, the reduction of energy consumption is motivation enough.
