Hi,

temperature in biogas plants is every time a strong parameter related to NH3 inhibition.

NH3 is in function of temperature, pH value and NH4, with an increasing temperature you get more inhibiting NH3.

NH3 is a very strong inhibitor to methane bacteria.

With a higher temperature you get more methane from CO2 and H2, therefore you need more and different trace elements.

NH3 inhibition- easily to combat with zeolite.
