Just like your doctor may order a variety of tests based on your symptoms to determine what’s wrong with you, at Digester Doc we have several tools we can utilize. The TND is a first-stage test that can identify issues in your digester, in many cases, early enough to head off costly treatments or unexpected shutdowns.
Often a TND is a first stage test conducted to identify the levels of critical trace elements within your feedstock. By identifying which elements are unbalanced in your system the TND study can inform possible remedies. A single imbalanced element can significantly reduce methane yield potential. Positive increases of 20 – 400% in biogas production have been observed by bringing the AD to optimal concentrations in these various trace elements.
Over 20 different trace elements are screened, including:
The concentrations of these elements are then assessed against the levels that we have determined are optimal for production, deficient (too little), prohibitive (too much), or toxic (poisoning your digester). These elements also need to be compared to one another, as several elements interact differently with each other based on their concentrations.
At the conclusion of this study, you will receive a full report detailing:
Once your test is scheduled, you’ll receive detailed instructions on how to sample and send it to us for testing. Once we receive your sample we’ll begin the TND testing which generally takes less than two weeks. Following the completion of the study, we’ll schedule a call to review the results with you.
