Dear All, I am working at a rural electrification project in India where anaerobic digestion will partly contribute to the energy supply. The community has proposed the use of aquatic weeds (water hyacinth, salvinia etc.) as one feedstock for AD, as they are already collected for the maintenance of canals and ponds. The desired biogas production is around 50 m3/day
The literature is full of informations about lab scale experiments with aquatic weeds; however I could not find many examples of successful full scale digesters operated with this feedstock. I am mostly interested in the reactor design and pretreatment solutions that have been adopted to address the characteristics of this feedstock (tendency to float, low solids content, etc). For example, it is reported that using aquatic weeds in unmixed rural digesters can lead to outlet blockages or scum formation: http://www.docstoc.com/docs/91988078/Energy-from-Anaerobic-Digestion-of-Phytomass-An-Enduring-but http://eprints.iisc.ernet.in/2387/1/evolving.pdf Can anyone share successes or problems with this feedstock? suggested pretreatment methods (chopping, grinding, silaging, drying...)? any attempt with leaching bed/solid phase systems? many thanks davide - -- --- Davide Poggio PhD Candidate Energy Technology and Innovation Initiative (ETII) Third Floor Open Space - Energy Building Faculty of Engineering The University of Leeds Leeds, LS2 9JT, UK T: +44 (0)7936325660
