Abstract
The kenics static mixer (KMS) has been profoundly used in water and wastewater treatment processes, essentially in water ozonation for oxidation and disinfection purposes. since higher concentration of ozone is required, new contactors which operate efficiently at low gas/liquid ratio has been developed. The Kenics static mixer can fulfil these demands which lead to increase in the ozone mass transfer rate [1]. The main purpose of this paper is to use the steady state back flow cell model (BFCM) developed by Tizaoui and Zhang [1] so as to estimate the concentration profile of ozone in the liquid and the gas phases along the KMS. The study also aim to develop a Matlab code for the BFCM of the static mixer. Moreover, this research studied the effect of the main operating parameters: volumetric liquid mass transfer coefficient ,the length of the Kenics static mixer, flow rate of water , and gas flow rate , back flow ratio and the temperature on ozone concentration profile in the gas and liquid phases and respectively along the height of the Kenics static mixer.
