The fermentation biogas and sludge

The final stage in the cycle studies is to determine all of biogas which includes:
determine the daily production of biogas
determine the percentage of methane, carbon dioxide and hydrogen sulfide
The fermentation residue obtained is subjected to further analysis to determine:
- the degree of fermentation of organic matter
- calorie
- total nitrogen content and ammonia
- Content P, K, Ca
- heavy metals
