Industrial anaerobic digestion process simulation

With the aim of knowing the performances of anaerobic digestion on an effluent and of determining the purifying outputs an anaerobic digestion reactor is supplied uninterruptedly by the industrial effluent during 3 to 6 months. The deployed technology is that of a fixed bed: Proveo™.









Réacteurs de méthanisation de 5 litres

We implement a traditional reactor for solid waste also called CSTR for Completely Stirred Tank Reactor.

Study of the Co-digestion of various waste

We perform a study of the anaerobic digestion of several waste simultaneously to determine their synergies (for example with an aim of balancing the sources in nutrients: Liquid manure (weak report/ratio C/N) + grease (important report/ratio C/N)) and their methane potential

Aerobic treatment of effluent

Our laboratory has the equipment enabling us to simulate the aerobic treatment of effluent slightly charged in organic load: Sequencing Reactor Batch

Stripping/absorption (depollution of nitrogen)

The study of stripping/absorption consists in determining the output of purification obtained on nitrogen in the form of ammonia (NH4+) by the passage in a column of degasification. Stripping makes it possible to recover nitrogen in very concentrated form.




Crystallization (depollution of phosphorus)

The equipment of our laboratory enables us to measure the rate of crystallization of phosphate by addition of magnesium hydroxide.

Decalcination (depollution of calcium)


The objective of the test is to determine the performances of a process of decarbonation to lime in term of purification output on the ions Ca2+ calcium. The test is based on a reaction of precipitation of the ions calcium in particular of the hydrogen carbonates with calcium hydroxide.
