There are several options you can try, one link (https://www.bioprocesscontrol.com/) is given as an example what we use in our lab. But the biochemical methane potential tests can also be performed in the bottles, and gas measurement can be done by simple gas measuring device ( http://www.keison.co.uk/geotechnical_biogas5000.shtml ) and a pressure meter ( http://gms-instruments.com/products/sika/mh-3181-hand-held-pressure-meter ). There is not many things required for that actually.

Follow the set up used by Dr. Tong Liu in his thesis (page 29) Thesis Biogas production from lignocellulosic agricultural residues...

Helllo Amin,

Try Biotech-india, they have small scale bio-digesters for lab&test work. You will need to close the inlet and out let for using as batch, it will give you opportunity to use as continuous digester as well. Their price after shipping and handelling will still be under your budget.

Best of luck,

Tarek

Hello Admin, in our lab we use AMPTS from Bioprocess, that is a very reliable equipment with a robust standardized procedure to analyse biogas production from different organic substrates in a batch mode, and is often used in literature studies. We made hundreds of tests during a period of more than 5 years, without big technical problems, except from a re-calibration a couple of years ago. Probably the required bugdet, however, should be higher than 7,000 $.

Kind regards,

Matia

Established for 8 years and transparent prices

Hello Amin, I don't know the exact prices, however, the standard guidelines that you are going to use for the batch test should be also considered as you buy your equipment, as it has been proven to influence the results.

A quick look at Table 4 in this report from the International Energy Agency (IEA) could give a perspective of equipment plus the established standard procedure.

Dear Amin,

for robust, inexpensive and yet precise BMP determination you can use the Gas Densitiy Method:

Article Development and Validation of a Low-Cost Gas Density Method ...

You can find additional (and mostly open access) documents on our website on BMP Methods:

If you have specific questions, please let us know.

Best regards and take care,

To enable expanding the limits of BMP tests we have developed an optional automatic feeding upgrade. It allows those working on suitable substrates to operate up to 10 out of the 15 reactors in each set as fully automatic feed digesters. I take the liberty to attach a description here. But, true, there are several methods in the market quite comparable. It just depends on how far you want to go. After all, the BMP is meant to be a simple test. Greetings to all colleagues and friends and I hope we can all meet again at some point when exchange of experience opens up again in live conferences, by the way
