Ultrasonic Disintegration of Sewage Sludge to Increase Biogas Generation
Renewable energy will play a key role in the future in limitation of greenhouse gas emissions, with particular focus on carbon dioxide. Biomass and waste are considered among the dominant renewable energy sources. Due to their availability on the energy resources market, it has potential to ensure permanent energy generation.1–3 According to the International Energy Agency (IEA), fossil fuels a...
متن کاملSonicated Sludge as Carbon Source for Denitrification
Ultrawaves sludge sonication technology was trialled at Maroochydore STP from February to June 2013. This was believed to be the first fullscale application of mechanical sludge lysis for enhanced denitrification in Australia. The results of the trial confirmed that sonicated waste activated sludge (WAS) could effectively replace the use of methanol as a carbon source for denitrification, and t...
متن کاملBiogas generation from floral waste using different techniques
There is a great need to implement low-cost and user-friendly methods for further propagation of biogas technology in India. Environment unfriendly disposal of floral waste causes serious environmental pollution. Literature shows a limited research work regarding the anaerobic digestion of floral waste for biogas generation. The present experimental work aims to propagate floral waste as a sus...
متن کاملIs 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...
متن کاملEffect of Sludge Pre-Treatment Techniques on the Biogas Production from Waste Activated Sludge
Introduction There is a significant and inevitable fact in Turkey which is the “sludge problem” generated from the wastewater treatment plants. There are many sludge disposal techniques currently applied in Turkey such as incineration, landfilling, composting, etc.; but the disposal of sludge with those conventional methods is difficult and expensive, often requiring over 50 per cent of the ope...
