PRETREATMENT OF AGRICULTURAL RESIDUE AS FEEDS TO PRODUCE BIOGAS

摘要

The present invention provides a method for pretreatment of agricultural residue. The method uses physical and mechanical means to change floating nature of the agricultural residue to a bottom settling sludge and enables to form slurry that can be pumped easily. Further, the method ensures that any scum formed on the surface is made to sink thus ensuring a continuous contact of the biological matter with the microbial consortia.
