The bio-augmentation processes of MADEP allow to better treat :


  • Urban and industrial wastewater (activated sludge, SBR biofilters, MBR etc…)

  • Bioremediation of contaminated sites (soils, groundwater and industrial effluents)

  • Digesters to boost biogas production under mesophilic and thermophilic conditions

  • Landfill leachates (elimination of organic and nitrogen pollution, more biogas)

  • MADEP currently has 6000 strains of bacteria, and hundreds of fungi, which are useful for bioprocessing and bio-remediation applications for a large number of different environmental and industrial sites.

  • MADEP micro-organisms are 100% ecological and applicable in the form of bioprocesses on a global scale.
