ABSTRACT

Water is one of the greatest essences in today’s world. Treatment of waste water could solve a lot of problems faced by modern world. Motive of this study is to treat industrial waste water. We know that to treat industrial waste water packed bed bioreactors are installed in some of the industry. In the present study, to understand performance of reactor we did develop a CFD model. By observing change in conductivity of tracer solution we measure the values of experimental RTD. Then solution for transport equation for geometrical configuration of a reactor is found via CFD simulation. The result obtained by CFD simulation & experimental value of RTD were compared to have a better design and to find out optimum conditions of a packed bed reactor. Experimental results are in hand-to-hand with those of CFD simulation.
