Abstract:

The paper describes the effect of temperature, ammonia concentration and feed flow rate on nitrifyingtreatment of wastewater usage Computational Fluid Dynamics (CFD) for two phase bubbly flow in a splitcylindrical airlift reactor with a 0.085 m initiator diameter and 0.505 m height. Superficial gas velocity was usedas the operational parameter, air was used as the dispersed phase, and wastewater containing ammonia wasused as continuous phase. Temperature enhancement in a constant O and NH concentrations, resulted the 2 4+increase of reactions rate also NO had an increase of about 3 times as much. By the feed flow rate increase, 2-O consumption increase and the rate of NO production increase more than NO but decrease the reactions 2 2 3- -efficiency decrease in a constant time. NH concentration enhancement leads to the increase of O 4 2+consumption and better reactions efficiency at higher NH concentration, NO concentration increases more. 4 2+ -Modeling results are compared with the experimental data. The CFD modeling results show suitable agreementwith the experimental data
