Anaerobic digestion of stillage to produce bioenergy in the sugarcane-to-ethanol industry
(2013-09-20)
Stillage is the main wastewater from ethanol production, containing a high chemical oxygen demand in addition to acidic and corrosive characteristics. Though stillage may be used as a soil fertilizer, its land application ...
Macromolecular composition and anaerobic degradation of the sludge produced in a sequencing batch reactor
(Pontificia Universidad Católica de Valparaíso, 2008)
Optimal synthesis of anaerobic digester networks
(ELSEVIER SCIENCE SA, 2009)
The objective of this paper is to develop a mathematical model for the synthesis of anaerobic digester networks based on the optimization of a superstructure that relies on a non-linear programming formulation. The proposed ...
Methane production from anaerobic digestion of dairy grease trap waste: Effect of sugarcane bagasse addition
(2021-01-01)
Lipids are attractive substrates for anaerobic digestion due to their high methane production yield. However, high concentrations of lipids may cause problems in anaerobic processes. Typically, grease trap waste is ...
Evaluation of a novel anaerobic co-digestion system for disposal of dead swine and manure: An important tool in animal production
(2020-06-01)
Purpose The anaerobic digester for dead animals is the most eco-friendly and cost-effective way to dispose of this waste. The aim of this study was to evaluate the removal efficiency of organic matter and pathogenic ...
Responses of anaerobic microorganisms to different culture conditions and corresponding effects on biogas production and solid digestate quality
(2016)
Microbial communities of anaerobic digestion have been intensively investigated in the past decades. Majority of these studies focused on correlating microbial diversity with biogas production. The relationship between ...
Metals in sugarcane molasses wastewater subjected to thermophilic anaerobic digestion
(2020-05-03)
This study evaluated the occurrence and removal of eleven trace elements, B, Co, Cu, Fe, Mn, Mo, Ni, Se, V, W and Zn, from sugarcane molasses wastewater through a thermophilic anaerobic structured-bed reactor (AnSTBR). ...
Predominance of syntrophic bacteria, Methanosaeta and Methanoculleus in a two-stage up-flow anaerobic sludge blanket reactor treating coffee processing wastewater at high organic loading rate
(2018-11-01)
The effect of the organic loading rate (OLR) on the performance and microbial composition of a two-stage UASB system treating coffee processing wastewater was assessed. The system was operated with OLR up to 18.2 g COD (L ...
Viability of Bovine`s Strongyloidea eggs in a System of Anaerobic Biodigestion
(Sociedad Chilena de Parasitología, 2004)
