Abstract(s)In the sequence of the work done with a combined ATV and double exponential model to describe the secondary settler concerning the optimal design of a wastewater treatment plant (WWTP), a simple sludge treatment based on dewatering followed by deposition in landfills is now included in the system. Power consumption, transport and deposition of the sludge are involved in the operation cost of the sludge treatment. This work aims to evaluate the contribution of this cost in the WWTP design total cost. The experiments carried out with three WWTPs in design show that the considered wasted biosolids treatment does not affect the design although is responsible for 10 to 14% of the total costs.
