C/N ratio in anaerobic digestion: why 20-30 is the optimal range
The C/N ratio (carbon-to-nitrogen ratio) is the parameter that measures the nutrient balance of the digester diet. The optimal range is between 20 and 30: below 15 there is excess nitrogen and a risk of ammonia inhibition; above 35 nitrogen is lacking and digestion slows down. Almost no substrate is in the ideal range on […]
