| Abstract | ||||
| Municipal Sludge Treatment is a first priority issue in high populated countries like Egypt. Building materials properties were employed in treating sewage sludge. Adding water to cement and lime creates alkaline media, which raises pH of sludge for certain period of time. High pH ensures getting rid of pathogens in the treated sludge. Unlike industrial wastes, Cement Kiln Dust is similar to Cement composition with less specification. An investigation of several alkaline building materials was conducted to compare the influence of mixing them with sewage sludge. Using by-product Cement Kiln Dust proved to be effective and was lime competitive. Fresh collected Cement Kiln Dust has a larger potential in raising pH than that of stored one. Cement Kiln Dust as well as lime achieved Class B specifications. Using Cement Kiln Dust proved to be effective and cheap treatment of Municipal Sludge | ||||
