SLUDGE DRYING BEDS – REVIEW CHECKLIST

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.

Sludge Drying Overview - Treatment Methods and ...

The existing 36 Sludge drying beds (SDBs) are provided each 27.5m × 55m in size. The Sludge drying beds are designed for a maximum sludge depth of 200mm of raw sludge (Howard Humphrys, 1995; Consul Aqua Humburg,2000). In a typical sand drying bed, sludge is placed on the bed in a 200 to300 mm layer and allowed to dry.

The relationship between net bed loading and solids content was found to be (Figure 2): Z = 0.057 SQ - 0.082 (3) 2 where Z = net bed loading of solids (kg/m /day) SQ = solids content (%) of sludge charged to the bed Although Haseltine's equations are strictly empirical, they have been used for the dimensioning of sludge drying beds.

Merit Filter – The Future of Dewatering

Fluidized bed drying system Drying in a closed inert gas loop The process Fluidized bed dryers for drying dewatered sewage sludge operate in a closed inert gas loop. The entire heat required to evapo - rate the water is fed to the dryer via heat exchangers, i.e. without any direct contact between the heat transfer medium and the product.
