Simulink Application On Dynamic Modeling Of Biological Waste Water Treatment For Aerator Tank Case
TLDR
In this article, Simulink modeling on Matlab is developed based on aerator tank model, which consists on movement of particles settled on bottom of the tank, by using air bubbling process.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 bacteria’s. Finally this model could be improved by considering a slow increase of flow rate.read more

Unraveling oxidation behaviors for intracellular and extracellular from different oxidants (HOCl vs. H2O2) catalyzed by ferrous iron in waste activated sludge dewatering
Wenbo Yu,Qianqian Wen,Jiakuan Yang,Keke Xiao,Yuwei Zhu,Shuangyi Tao,Yang Lv,Sha Liang,Wei Fan,Suiyi Zhu,Bingchuan Liu,Huijie Hou,Jingping Hu +12 more
TL;DR: Two kinds of oxidation behaviors from different oxidants catalyzed by ferrous iron were comparatively investigated and sludge pretreatment based on Fe2+/Ca(ClO)2 could achieve simultaneous deep-dewatering performance and total coliforms inactivation and be regarded as "Intracellular oxidation".
