Última Methane Production by the Anaerobic Digestion of Tall Fescue samples pre- and post-ensiling, prepared by Thermal (40°C) or Freeze Drying CIGR Journal McEniry, Joseph; O'Kiely, Padraig. Herbage samples for small-scale batch digestion tests are often dried and milled to provide smaller representative sub-samples for analyses.  Thermal drying, however, can change the chemical composition of a feedstock and these changes may impact on specific CH4 yield.  Consequently, freeze drying is often the preferred system for drying grass samples.  However, additional difficulties are encountered when evaluating silage samples as a result of the loss of volatile compounds during both thermal and freeze drying.  As grass and grass silages are readily used as feedstocks for biogas production, the impact of drying method needs to be considered for herbages pre- and post-ensiling.  This study investigated the effects of thermal (40ºC) and freeze drying on...

Ano: 2014 URL: http://www.cigrjournal.org/index.php/Ejounral/article/view/2196 Sanitation and Drying of Sewage Sludge on Radiant Floors Using Solar Energy and Biogas: Comparison between Different Thicknesses of Deposited Mass BABT Gontijo,Jéssica Cristine; Wagner,Luiz Gustavo; Souza,Mariana Espíndola de; Possetti,Gustavo Rafael Collere. ABSTRACT Sewage sludge is a solid waste composed of water, rich in organic matter and nutrients, but concentrator of pathogenic microorganisms. Its use as agricultural fertilizer in the state of Paraná, Brazil is common. However, it is necessary to eliminate or significantly reduce microorganisms by means of a hygiene process. This can be obtained thermally, requiring a source of energy for heat generation. In this sense, a pilot system was constructed consisting of a stainless steel radiant floor, capable of transferring heat to the sewage sludge from coils coupled in base, through which the heated water circulates. The energy comes from solar radiation and is complemented by biogas from the anaerobic sewage treatment. Aiming to investigate the system's...
