The products (bioprocesses) of MADEP composed of aerobic and / or anaerobic microorganisms are provided in different formulations :


• Chilled liquid suspensions

• Dried on fine granular substrates

• Frozen liquid suspensions


The microorganisms selected are produced separately in the laboratory and then mixed in consortia and supplied periodically.


The micro-organisms are used directly with and without prior dilution or before use they are multiplied on site for 24-48 hours in cubitainers of 1-20 m3.


Microbiological monitoring is performed to ensure optimal treatment.
