Combining sludge hydrolysis with predenitrification is a promising method to remove nitrogen and decreased use of external carbon content in wastewater. The Klagshamn wastewater treatment plant plans to alter the primary settler into an in-line hydrolysis basin with subsequent predenitrification to reduce the nitrate load into the overstrained moving-bed biofilm reactor. A reference scenario, which included annual data from the process control system, was established and calibrated with the operational findings from the plant in 2007 to form a dynamic wastewater model. A method for generating a complete annual data set based on laboratory values was established and implemented with the model. The... (More)

In addition, the simulated results of the proposed in-line hydrolysis basin were used to evaluate the potential for predenitrification. The results with hydrolysate showed that an additional 40 t·a-1 of nitrogen could be denitrified compared to

the reference scenario. (Less)
