Membrane separation processes often is a simple and cheaper alternative to traditional separation processes such as evaporation, liquid-liquid extraction and distillation. The membrane group at SDU-ChE has specialized in low temperature separation and concentration of high value metabolites and proteins from plant, algae and animal extracts. Further we investigated the feasibility of separation and concentration of fertilizers such as potassium, ammonia and phosphates from animal slurry.
The membrane group at SDU-ChE combines this effort with SDU-CEBE’s general knowledge on analytical chemistry, process design & simulation and process economy evaluation to optimize the membrane process from both a resource and economic point of view in order to give a sustainable production.
