Methane potential determination of biomass

Determine your methane potential

The batch experiment to determine the methane potential is the scientific standard method for determination of the maximum methane production of a substrate and the gain of standardized, comparable information. In a short time with minimal effort, data on kinetics and disintegration behavior can be realized helping you take advantage of hidden potentials in your system.

 

AMPTS

The Automated Methane Potential Test System (AMPTS) of Bioprocess Control allows Ultrawaves to achieve very accurate results very quickly (about 30 days). The AMPTS consists of:

  • Stirred, temperature-controlled digestion vessels with 500 mL each
  • An CO2-/H2S-absorption stage
  • An automated eudiometric measuring and recording of the methane produced

The AMPTS is comparable to conventional, scientific systems for determination of methane potentials and meets the standards set by the VDI guideline 4630 on the fermentation of organic matter.

 

Efficiency gain through ultrasound technology

Through use of innovative ultrasound technology by Ultrawaves an intensification of the anaerobic digestion process is achievable. This increases the efficiency of the entire plant, improves the biogas yield (up to 15% for biogas plants and up to 30% for sewage treatment plants) and thus reduces the amount of fermentation residue which has to be disposed of.

As shown exemplary in the figure, methane potential tests can highlight the possible efficiency increase. For this purpose the methane potential of your untreated biomass is compared to the potential after the ultrasonic treatment. The result can be used as a basis for further analyses or a practical test run of our ultrasonic disintegrator on your facility.

 

Characteristic development of the methane release from blank, reference sample, untreated sample and sonicated samples over time.

 

The reference sample provides information about the biological activity of the inoculum and enables conclusions about the total degradability of the ideal substrate such as cellulose. The difference in methane yield of the blank and the untreated sample is the yield of the substrate. The increase of methane yield due to the ultrasound treatment can be determined from the difference between the untreated and sonicated sample.
