Mesophilic and psychrophilic digestion of liquid manure
IN GENERALIn this thesis the possibilities for digestion of cow and pig manure are described for a completely stirred tank reactor system (CSTR) and an accumulation system (AC-system).For this purpose were researched:1. Anaerobic digestion of cow manure. Optimization of the digestion process for energy production on dairy farms.2.

Climate impact of alternative organic fertilizers using life cycle assessment
Environmental Research LettersAnaerobic digestion is a common method for managing liquid manure and other biomasses, generating biogas as a renewable energy source. The resulting digestate can be processed into organic fertilizers to enhance nutrient recycling, but its environmental ...

, 2017 Agricultural and centralized biogas plants are facing a fast development, leading to the production of huge amounts of digestates. Whereas the solid fraction of digestates is used as fertilizer, the liquid fraction can be valorized by the recovery of mineral materials, although the presence of organic compounds may be problematic for the treatment and ...

Characterisation of the liquid fraction of digestate after solid-liquid separation
, 2015 Samples of the liquid fraction of digestate from 6 mesophilic anaerobic co-digestion plants after solid-liquid separation were characterised. The samples represented different types of substrates, different AD process parameters and types of solid-liquid separation devices.
