The sludge settled from the UASB is put for sun drying on the Sludge Drying Beds. Faecal sludge and septage collected from s and community toilets are transferred through vacuum trucks. It is first emptied into collection tank at the FSTP to homogenize the content. The homogenized FSS is then conveyed to clarifier tank for settling ...

Sludge drying bed (SDB) is the most widely used method for sludge dewatering. Sludge drying involves natural ways of drying to mechanical ways of removing water content. SDB is generally used for small and medium sized communities (TCHOBANOGLOUS et al. 2003). The selection of the technology will depend upon land availability, climatic factors, the quantity and composition of the sludge.
