Multicriteria Assessment of Alternative Sludge Disposal Methods
Sludge production from wastewater treatment process is high, and the disposal of excess sludge will be forbidden in a near future, thus increased attention has been turned to look into potential technology for sludge reduction. The study attempts to review alternative sludge disposal methods, including anaerobic digestion, aerobic digestion and landfills. In these sludge processes, excess sludg...

متن کاملSustainability of Domestic Sewage Sludge Disposal
Activated sludge is now one of the most widely used biological processes for the treatment of wastewaters from medium to large populations. It produces high amounts of sewage sludge that can be managed and perceived in two main ways: as a waste it is discharged in landfill, as a fertilizer it is disposed in agriculture with direct application to soil or subjected to anaerobic digestion and comp...
متن کاملEnvironmentally Sound Disposal of Tannery Sludge
The challenging problems faced by the tannery based countries are the safe disposal of the sludge generated by the effluent treatment plants. In this work, the disposal of the sludge at various generation points such as beam house (BHS) and after tertiary treatment process (TS) is studied. The FT-IR of the beam house sludge confirmed the presence of organic matter at 2880.31cm -1 and calcined p...
