Ozone is mostly used as disinfect in water treatment. To determine the performance of purify stage in waste water treatment; computational fluid modeling can be a useful aid. Contactor tanks are designed to take help of the contact time between ozone and pathogens before the water are release to clients. Thus the design plan is to exploit on the time that it takes for water to travel from the tank influent to the effluent. In present analysis Tracer studies can be used to determine the hydraulic characteristics of the ozone contactor tank. Residence Time Distribution (RTD) analysis is a very efficient analysis tool that can be used to inspect the malfunction of ozone contactor tank. The result from tracer studies can used to obtain precise estimate of the efficient contact time. The effects of opposing tank flow condition and different geometry arrangement are studies using CFD.

Keywords: CFD; Residence Time Distribution; Contact tank; Tracer; Hydraulic.
