Acid-phase and Two-phase Codigestion of FOG in Municipal Wastewater
Acidogenic codigestion of fats, oils, and greases (FOG) was studied at 37"C using suspended sludge digesters operated as sequencing batch reactors (SBRs). Volatile fatty acid (VFA) production was found to increase with larger FOG loading rates, although this increase was insignificant compared the …

Thermal Hydrolysis of LCFAs and Influence of pH on Acid-phase Codigestion of FOG
Two different sludge pretreatments were investigated in an attempt to improve the management and performance of processes for the co-digestion of biosolids with fats, oils, and grease (FOG). The mechanisms of long chain fatty acids (LCFA) degradation in thermal hydrolysis pretreatment and the …

Pre-treatment and anaerobic codigestion of waste activated sludge from a petrochemical wastewater treatment plant
During the aerobic treatment of wastewater, waste activated sludge (WAS) is generated which requires further treatment. The typical treatment method applied for treating the sludge is incineration. The National Environmental Management: Air Quality Act (NEM:AQA), promulgated in 2004, was amended in …

Estudio técnico-económico de la digestión anaerobia conjunta de la fracción orgánica de los residuos sólidos urbanos y lodos de depuradora para la obtención de biogás
… fraction of municipal solid waste (MSW), and codigestion sludge-MSW, as well as a brief economic analysis based on values obtained by the biogas. The second study compares two phases and monoetapa technologies, using a mixture of sludge-MSW as a substrate for codigestion, depending also on TS, …

Recovering biomethane from fats, oils, and greases: Examining the impacts of microbial ecology on anaerobic codigester stability and bioconversion kinetics
… manure. Yet, biomethane recovery from FOG codigestion at wastewater treatment plants or agricultural digesters can be limited due to process inhibition caused by long-chain fatty acids (LCFA) accumulation. Currently, there is a lack of understanding regarding the role of anaerobic digester …

Avaliação da produção de hidrogênio e metano a partir da codigestão anaeróbia de resíduos
… of hydrogen and methane through anaerobic codigestion in two phases (acidogenesis and methanogenesis) of organic waste (OW), sewage sludge (SS) and raw glycerol (GL), was investigated in batch assays under temperature controlled conditions. The effect of glycerol addition (1 and 3% v/v) as …

Onpeak Market Dispatchable Energy From Megawatt Scale Fuel Cells And Stored Digester Methane
… the rest can employ clustering agreements and codigestion of food waste streams to achieve similar revenue streams. The analysis demonstrated several beneficial combinations: • clustering digester sites by pipelines to make more than 1 MW fuel cell power plants if methane supply from one …

Alternative Waste Treatment System for Poultry Processing Plants
… for biogas recovery from TPW and can be used for codigestion with some specific turkey processing byproducts for biogas recovery. Nitrogen and phosphorus removal in the A2N-SBR system were 47% and 75%, respectively, and during the study the nitrogen and phosphorus removal mean concentration in …
