Buoyant Density Separations

  • Research project

So-called Buoyant Density Separations (BDS) is a separation method, like distillation or filtration. It is a technology that allows materials to be separated from each other in a solvent. The aim is to adjust the density of the solvent so that it sits between the density of the materials you want to separate. This makes the lighter material float and the heavier material sink. It is a sustainable separation method that can be used in industry.

In the BDS project, an energy-efficient, sustainable, readily scalable and non-destructive separation technology is being developed. This method fits into the requirements of green chemistry and contributes to the biobased and circular transition. Residual streams (from the agricultural industry, for example) can potentially be separated with the BDS technology and then used for commercial applications. The solvents used can be recycled/reused. This technology also offers opportunities in the pharmaceutical industry to produce and/or develop new and existing drugs in a better way.
