PRODUCTION OF BIOGAS FROM ORGANIC MATERIALS

摘要

Waste or organic material is compressed at a pressure sufficient to burst cells, for example 50 bar or more, and separated into a dry fraction and a wet fraction. The wet fraction is treated in an anaerobic digester to produce biogas after removing grit. The wet fraction is diluted, preferably with sludge, before it is degritted. Optionally, floatables are removed from the fraction before it is added to the digester.
