Effective management of faecal sludge through co-digestion for biogas generation

Co-digestion of Sewage Sludge and Microalgae- Biogas

Enhancement of biogas potential of primary sludge by co-digestion with cow manure and brewery sludge

Anaerobic digestion (AD) has long been used to treat different types of organic wastes especially in the developed world. However, organic wastes are still more often considered as a waste instead of a resource in the developing world, which contributes to environmental pollution arising from their disposal. This study has been conducted at Bugolobi Sewage Treatment Plant (BSTP), where two orga...

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

Is sonication effective to improve biogas production and solids reduction in excess sludge digestion?

Results of three semi-continuous anaerobic tests were reported and discussed. Each test was carried out by two parallel anaerobic reactors fed with waste activated sludge, either as it was sampled from the sewage treatment plant of Rome North or previously disintegrated by ultra-sound treatment. Activated sludge was sonicated at the energy input of 5,000 or 2,500 kJ kg(-1) dry solids correspond...
