Over 20 different trace elements are screened, including:
- Arsenic, which is toxic to anaerobic organisms
- Iron, which has stimulatory effects that increase the biogas production
- Manganese, which is an enzyme activator
- Cobalt and Nickel, both of which are essential for the reproduction of Methanogenic organisms.
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.
