Extraordinarily effective – brown coal and microbiology The biological degrading of pollutants in waste water Thanks to our new technology, even pollutants which have been regarded as non-degradable (e.g. thiourea) can be removed from waste water using microorganisms. This creates new solutions for the degradation of substances harmful to the environment e.g. for the electronic and circuit board industries. Cleaning of waste water containing heavy metals Following the biological cleaning of solutions and waste water containing heavy metals, the metals could no longer be detected. At the same time, the metals in the solutions could be reclaimed in their pure forms (galvano technology). The use of brown coal for the protection of the environment Newly developed brown coal filters have been used successfully for the cleaning of oil-water mixtures.
