Small-scale Processing Plant of Sewage Sludge for gas / electricity / product production

Published on by in Academic

So the current wastewater per day is about 20000 litres, with a solid content of 4000mg/litre

About 60kg of solid a day, assume 40% of it is removed in treating, leaving about 48 kg a day of solid

Volatile solids is about 70%

Any ideas of what, if any processing plants on a very small scale or even just units, that can be used to make something that is economically viable, whether it be incineration, composting, anaerobic digestion, pyrolysis etc

 

Current cost of disposal is £8000 a month , so worth taking it into account for payback time
