Environmental Engineering 2015




The students were provided with copies of chapter 14: “Sludge Thickening, Dewatering and Drying” from the book “Wastewater treatment plant design. IWA Publishing 2003”, together with some data about initial flow rate, sludge composition and removal efficiencies.


In groups, they read the material, build up the flow diagram of the process and performed the mass balance in order to obtain the intermediate and final water and sludge flow rates, the intermediate compositions, and the size of the final disposal equipment.
