All of our representatives are degreed individuals
from diverse backgrounds with hand-on operation
experience of biological treatment processes.

Our Treatability Lab is one of our many tools used to predict
and troubleshoot problems for multiple industrial waste streams.

We don’t just sell products, but turn key Product Programs
that link our products to regular laboratory testing and technical
assistance together to keep biological treatment systems fully optimized.

Anaerobic Micronutrients

Anaerobic micronutrients play a crucial role for the biology in anaerobic processes. Anaerobic bacteria, such as methanogens, use trace metals to develop specific enzymes to breakdown organic material. Without these trace metals the bacteria can become bottlenecked, create excess volatile acids, handicap reproduction, and hinder biogas production.

Cobalt, Copper, Manganese, Molybdenum, Nickel, Iron, and Zinc are just a few of the most important anaerobic micronutrients. The bacteria use these elements to make metaloenzymes that can cut apart organic material. One specific enzyme called F-430 is the final step of biogas production. Bacteria cannot synthesize F-430 without Nickel. A reactor that is void of Nickel would be unable to make methane. A deficiency in any of the other metals can have a similar affect.

Metals in the water can be analyzed by using AA or ICP. But the presence of these trace metal does not always indicate that the metals are “available” for use by the bacteria. If any of these metals form a solid bond with another compound the metal becomes non-bioavailable. Chemicals like EDTA, sulfide, or carbonates can bind strongly to trace metals and become unusable by the bacteria. For anaerobic micronutrients to be usable by the bacteria they need to be in a bioavailable form, they need to be free metals.

Anaerobic micronutrients are often overlooked when troubleshooting or optimizing anaerobic systems. Visit the knowledge base section for Case Studies on how industrial systems have responded to supplementing with anaerobic micronutrients.
