  • Microorganisms purify ground water

    Press release / 1.9.1998

    Pilot plant

    Chlorocarbons are often found as contamintations in ground water and soil. A new two-stage biological process uses microorganisms to degrade these hazardous compounds and purify the ground water.

  • Bipolar memebrane

    Germany was the first country to enact a recycling (the so-called "closed loop economy") law in 1996: Instead of disposing waste it ensures the recycling or reprocessing of waste materials with the aim of saving natural resources. Fraunhofer IGB has developed a process for combined waste water purification and acid recycling. This not only protects the environment but also reduces costs.

  • Quality feed from sprouted seeds

    Press release / 2.3.1998

    Bioreactor

    Grain and sprouts have the potential to improve the quality of animal feedstuffs they contain all of the essential nutrients and minerals in a digestible form. A new germination procedure will enable sprouts to be produced on a large scale under controlled conditions.

  • Fixed-bed circulation reactor

    Fixed-bed reactors with immobilized biomass are applied increasingly in waste water purification. However, they have one disadvantage: Their flow channels block easily. Now, at Fraunhofer IGB a bioreactor has been developed, whose fixed-bed particles are circulated from time to time. This allows continuous, trouble-free operation.
