Methanogens Require Trace Elements
Methane production is both important for biogas and digester health. When methanogens don’t receive adequate food, the result is an overabundance of acid in the digester and a sharp drop in methane production.
Trace elements like cobalt, nickel, and iron are an essential component to the output of methanogenic bacteria. These bacteria need a steady supply of trace elements to form the enzymes necessary for methane production. Aquafix has developed a form of these crucial metals that is 100% bioavailable, which means the metals have been formulated to be completely absorbed by the bacterial cells. Putting in simple or commodity-based forms of these metals will not have any effect, as they are not taken up or used by the biology.

Additional Anaerobic Information
Case Study – Aquafix BioGas1
Challenge: A corn processing plant in Illinois lost methane production from their 500,000 gallon mesophilic anaerobic digester. As production increased, their methanogens couldn’t keep up. This caused COD levels as well as fats, oils and grease to rise in the supernate. This also contributed to upsets in the adjacent aeration process.
Case Study – Digester Foam & Methane Loss
Challenge: A municipal wastewater treatment plant in Kansas called with an anaerobic digester overflowing with foam. This digester has produced minimal methane for over two years, and within a week of the foaming issue, lost all methane production.
