Analysis of substrates of biogas plants


- silage, fermenter substrate, digestate, starch water, manure, slurry, brewer's yeast

According to the Ordinance on the protection of agricultural land from pollution:

Manure is solid manure, slurry, and manure as organic manure in processed form.

Solid manure is a mixture of litter, solid and liquid animal excrements of varying degrees of biodegradation, stability and maturity.

Slurry is liquid manure, most often a mixture of liquid animal excrement and wastewater (usually formed as a liquid residue of excrement that litter manages to absorb).

Parameters of substrate testing of biogas plants that we conduct:

  • pH
  • Dry matter
  • Chemical Oxygen Consumption
  • Anionic detergents
  • Ammonia
  • Sulfates
  • Chlorides
  • Organic carbon or organic matter
  • Nitrogen, total
  • Phosphorus, total
  • Potassium, total
  • Ember remains
  • Acid ratio (butyric: lactic: acetic)
  • Ashes
  • Microelements: Na, Ca, Mg, Cu, Mn, Fe, Mo, Zn, Co
  • Heavy metal: As, Cd, Ni, Pb, Cr, Mo, Co, Hg
