Direct nitrogen stripping and upcycling from anaerobic digestate during conversion of cheese whey into single cell protein.

Bioresource Technology, 2022
The environmental impact of the dairy industry is heavily influenced by the overproduction of nitrogen- and carbon-rich effluents. The present study proposes an innovative process to recover waste contaminated nitrogen from anaerobic digestate while ...

Anaerobic digestion of extruded OFMSW

Bioresource Technology, 2012
Organic fraction of municipal solid waste (OFMSW) was used to feed two pilot plants of 1000 l working in anaerobic conditions. The OFMSW had previously been treated using a system of extrusion which, due to exerted pressure, separates the undesired fractions of waste from organic waste and reduces the organic fraction in a kind of homogeneous jam ...

Use of biochars in anaerobic digestion

Bioresource Technology, 2014
This study investigated the behavior of biochars from pyrolysis (pyrochar) and hydrothermal carbonization (hydrochar) in anaerobic digestion regarding their degradability and their effects on biogas production and ammonia inhibition. A batch fermentation experiment (42°C, 63 days) was conducted in 100mL syringes filled with 30 g inoculum, 2g biochar ...

Modeling of Anaerobic Digestion of Sludge

Critical Reviews in Environmental Science and Technology, 2009
Anaerobic treatments have been successfully employed for more than one hundred years to stabilize sewage sludge. The main aim of sludge anaerobic digestion is the degradation and destruction of organic matter, with consequent sludge stabilization and pathogen reduction.

Anaerobic digestion of sewage sludge in an anaerobic fixed bed digester

Biomass and Bioenergy, 1995
The anaerobic digestion of sewage sludge in conventional reactors requires a hydraulic retention time of around 20 days. By using a fixed bed reactor the hydraulic retention time was reduced to 3–7 days. Recirculation increased the removal of organic matter in this system.
