Methane in the Storage and Dehydration of Sewage Sludge

Methane is released unintentionally at some points in the sewage sludge treatment process, such as during dewatering after digestion, storage of dewatered sludge or its further use. This article provides an overview of methane emissions during sewage disposal and in particular during the storage and dehydration of dewatered sewage sludge. It also describes processes for methane cleavage and oxidation, and relates to the practice of storage and drying of dewatered sewage sludge.
