Primary and Activated Sludge Biogas Production: Effect of Temperature

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2018
Sewage sludge management is a problem of growing importance. Anaerobic sewage sludge stabilization is commonly used technology, where organic matter contained in primary and activated sewage sludge is converted into biogas, so both, pollution control and

Assessment of co‐digestion of poultry litter and swine wastewater: the effect of enriched inoculum on biogas production

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Co‐digestion of substrates represents a viable strategy to enhance biogas production. This study evaluates biogas generation from the liquid fraction obtained through phase separation of co‐digested swine manure and poultry litter, to assess the influence of the inoculum‐to‐substrate ratio (ISR) and to analyze the effect of ...

Model based study of autothermal thermophilic aerobic digestion (ATAD) processes : a thesis presented in partial fulfilment of the requirements for the degree of Master of Technology in Engineering and Automation of Massey University [PDF]

, 2000
An Autothermal Thermophilic Aerobic Digestion process, or ATAD process, is a relatively new sewage sludge treatment process. The ATAD process has been developed for the disinfection and stabilisation of sewage sludge, which is a by-product of wastewater ...

Nitrous oxide mitigation potential of biochar derived from agricultural and forest biomass: Effects of feedstock composition and pyrolysis temperature

Journal of Environmental Quality, EarlyView.
Abstract Biochar application to soil has been promoted to mitigate climate change by reducing greenhouse gas (GHG) emissions, yet significant uncertainty exists in quantifying soil nitrous oxide (N2O) emissions from biochar‐amended soils. We evaluated soil N2O emissions from soils amended with biochar prepared from diverse agricultural and forest ...

Effect of sewage sludge on the incidence of corn stalk rot caused by Fusarium. [PDF]

, 2015
During the last decades, sewage started to be treated in order to reduce the pollution of rivers, resulting in the production of a sludge rich in organic matter and nutrients, called sewage sludge.
