Research

Research on membranes and membrane processes has a long tradition in Lund. Some current research areas:

Biorefineries

Environmentally friendly and energy efficient separation methods is a prerequisite for the sustainable use of biomass for energy and chemicals. This makes membrane processes key components in biorefineries.

Examples of projects:

  • Concentration and purification of dissolved solids in pulp mill process streams for energy and chemicals production
  • Isolation and fractionation of dissolved solids extracted from agricultural residues

Bioseparation

Membrane processes are used for cell separation and fractionation of proteins.

Fuel cells

Polymer fuel cells have great potential as efficient and environmentally friendly power sources in, for example, portable electronics, various types of vehicles and stationary power generation. Robust proton-conducting polymer membranes are central for the fuel cell's function, lifetime and performance.

Membrane bioreactor

Membrane bioreactors (MBR) are used to treat and reuse wastewater from industries and municipal sewage treatment plants. MBR is a relatively new wastewater treatment technology that is becoming more common as the lack of clean water increases.

Membrane emulsification

Creation of microemulsions by dynamic drop formation with the help of membranes.

Synthesis and modification of membrane material

The transport properties of polymeric membranes are dependent on the molecular structure and morphology of the membrane material. Therefore are methods to tailor membrane at different length scales for a particular application important.
