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 ...
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 ...
Influence of carbon sources and C/N ratio on EPS production in anaerobic sequencing batch biofilm reactors for wastewater treatment
(ELSEVIER SCI LTD, 2010)
The objective of this work was to evaluate the influence of different carbon sources and the carbon/nitrogen ratio (C/N) on the production and main composition of insoluble extracellular polymers (EPS) produced in an ...
Application of electromagnetic field in anaerobic biodigestion in batch reactors
(2020-08-01)
Anaerobic digestion processes with biogas production are widely used for organic waste treatment with an emphasis on energy recovery. Some recent studies have demonstrated the influence of magnetism on microbiological ...
Limonene removal using a horizontal-flow anaerobic immobilized biomass bioreactor
(2021-10-01)
In Brazil, a large amount of liquid wastewater generated during orange juice production has a significant negative impact on the citric industries. The treatment of this wastewater has been carried out in biological treatment ...
Improving the energy balance of ethanol industry with methane production from vinasse and molasses in two-stage anaerobic reactors
(2019-11-20)
Thermophilic anaerobic digestion is a viable option for processing sugarcane vinasse that recovers energy in the form of methane. However, restarting real-scale vinasse-treating reactors, at the resumption of the sugarcane ...
Combination of an anaerobic process with O(3), UV and O(3)/UV for cellulose pulp bleaching effluent treatment
(DESALINATION PUBL, 2009)
Recent studies have shown that partial oxidation by advanced oxidation processes (AOP) is able to transform hard-to-degrade compounds and increase their biodegradability. In this work, anaerobic treatment was followed by ...
Coagulation-flocculation of anaerobically treated sugarcane stillage
(2013-06-19)
Anaerobic digestion applied to stillage usually results in treatment performances. However, effluents from anaerobic reactors still present a residual polluting load due to the presence of organic recalcitrant compounds. ...
Methanogenic potential and microbial community of anaerobic batch reactors at different ethylamine/sulfate ratios
(Brazilian Society of Chemical Engineering, 2011)
Methylamine and sulfate are compounds commonly found in wastewaters. This study aimed to determine the methanogenic potential of anaerobic reactors containing these compounds and to correlate it with their microbial ...
