The aim of the study was to investigate the decontamination of pig slurry containing exotic viruses of pigs, foot AND mouth disease virus (FMDV), Aujeszky's disease virus (ADV) AND classical swine fever virus (CSFV). Laboratory-scale decontamination experiments showed that FMDV, ADV and CSFV were heat inactivated in slurry within 3 min at 67 degrees C, 3 min at 62 degrees C and 3 min at 60 degr...
Replacing process water and nitrogen sources with biogas slurry during cellulosic ethanol production
BACKGROUND Environmental issues, such as the fossil energy crisis, have resulted in increased public attention to use bioethanol as an alternative renewable energy. For ethanol production, water and nutrient consumption has become increasingly important factors being considered by the bioethanol industry as reducing the consumption of these resources would decrease the overall cost of ethanol p...
this study experimentally investigates the effect of multi-walled carbon nanotubes (mwnt’s), as a reinforcing material, on the physical properties of heavy-weight oil well cements. a candidate well is selected and the properties of the cement slurry used in a problematic section of the well are tested in the laboratory. carbon nanotubes (cnt’s) are added as fibers to the cement slurry and the i...
