Abstract
The rapid increase in sludge production creates the need for adoption of economically and environmentally acceptable sludge management schemes. This Chapter presents a review and investigation results concerning sludge generation, characteristics and effect of natural drying on sludge characteristics. The data presented in this chapter are mainly taken from an extensive research, conducted in order to determine the physical, chemical and microbiological characteristics of municipal sludges produced at three major cities, namely, Qateef, Dammam and Khobar in the Eastern Province of Saudi Arabia between April 2000 and February 2001. Sludge samples were collected, from sand drying beds, twice a season for one year and were analyzed for certain potential parameters. The chapter describes the effect of initial sludge depth in drying beds on the fate of pathogen, which is a unique approach for formulating mathematical representation to describe the pathogen die-off with respect to time and sludge initial depth.
