Abstract

The modelling results of BOD and COD for an aeration tank from Gherla’s WWTP by Matlab/Simulink software program has no significant difference, because the results are close enough to the real ones that allow the user to make a good prediction regarding this parameters. A true validation of these results, including experimental validation of simulations of the entire collecting data was realistic. Validated process models can be used for dynamic simulations, for example, with different kinds of input data. In simulations, the mathematical equations of process model are solved and the results given. Models and software for simulation have the possibility to control and evaluate the parameters. The presented control strategies use mainly ideal conditions, given the circumstances, for controllers and plant operations.
