Co-digestion of sewage sludge and crude glycerol for on-demand biogas production

Co-digestion of Sewage Sludge and Microalgae- Biogas

Co - Digestion of Municipal Biowaste and Sewage Sludge for Biogas Production

Abstact: The aim of the research project was to carry out the co-digestion of organic fraction of solid municipal waste in the form of source separated kitchen waste and sewage sludge. The influence of the kitchen waste as a co-substrate on the stability and efficiency of the process was determined. Mesophilic fermentation (36 ̊C) was conducted for sewage sludge as well as mixtures of sewage slu...

Biogas Production under Co-digestion of Food Waste with Sewage Sludge

Biogas Production from Fish Wastes in Co-digestion with Sewage Sludge

Fish wastes have great potential as a source of high valued organic carbon for methane production but also have limitation (high content of ammonia nitrogen). Anaerobic treatment of fish wastes is possible with co-digestion. The main issue for co-digestion process lies in balancing several parameters in the co-substrate mixture: macroand micronutrients, C:N ratio, pH, toxic compounds, biodegrad...

Anaerobic co-digestion of coffee waste and sewage sludge.

The feasibility of the anaerobic co-digestion of coffee solid waste and sewage sludge was assessed. Five different solid wastes with different chemical properties were studied in mesophilic batch assays, providing basic data on the methane production, reduction of total and volatile solids and hydrolysis rate constant. Most of the wastes had a methane yield of 0.24-0.28 m3 CH4(STP)/kg VS(initia...
