Abstract
Abstract Environmental protection and water quality preservation is an import task for each person in the world. In this paper importance of water quality is discussed in addition different waste water treatment processes are presented. Main objective of this paper is application of Simulink for dynamic modeling of biological treatment especially concerning to the activated sludge processes ASP. In connection with Simulink modeling different mathematical approach are presented and consider also during the simulation. Simulink modeling on Matlab is developed based on aerator tank model. Aerator model itself consists on movement of particles settled on bottom of the tank by using air bubbling process. Several simulations are done for two different cases dry weather and rain episode. Concerning to dry weather episode equilibrium of biomass and organic matter is reached after long period i.e. 200 days. While concerning to the rain episode there is a decrease of biomass and increase of organic matter also it is notice a significant growth of bacterias. Finally this model could be improved by considering a slow increase of flow rate.
