An experimental and modeling study has been conducted to develop a soft sensor able to predict the diurnal trends of the main variables affecting UV disinfection in such as water transmittance (at 254 nm) and influent microbial concentration (No) and microbial inactivation kinetics. Such soft sensor is based on a Copula-based approach calibrated on commonly-available plant data such as flowrate and other routinely measured parameters including NH4+, COD and TSS. Then, such model has been integrated into a plant-wide wastewater process simulation tool (i.e., Benchmark Simulation Model n.2, BSM2) in order to investigate the response of a UV system under dynamic conditions and compare various treatment scenarios. Results indicated that the size of the secondary clarifier plays a very important role in controlling water quality parameter affecting UV disinfection, and ultimately UV inactivation efficiency.

Abstract
An experimental and modeling study has been conducted to develop a soft sensor able to predict the diurnal trends of the main variables affecting UV disinfection in such as water transmittance (at 254 nm) and influent microbial concentration (No) and microbial inactivation kinetics. Such soft sensor is based on a Copula-based approach calibrated on commonly-available plant data such as flowrate and other routinely measured parameters including NH4+, COD and TSS. Then, such model has been integrated into a plant-wide wastewater process simulation tool (i.e., Benchmark Simulation Model n.2, BSM2) in order to investigate the response of a UV system under dynamic conditions and compare various treatment scenarios. Results indicated that the size of the secondary clarifier plays a very important role in controlling water quality parameter affecting UV disinfection, and ultimately UV inactivation efficiency.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione
