Background and purpose: Presence of natural organic substances in surface water supplies could be harmful and have adverse effects on drinking water treatment due to many practical and hygiene reasons. This study aimed at investigating the efficiency of catalytic ozonation process in removal and mineralization of humic substances in water resources in north of Iran. Materials and methods: Wate...

The current study aimed to examine the overall feasibility of the use of copper oxide nanoparticles (CuO-NPs) as a catalyst in ozonation process for the removal of benzene from aqueous solutions under experimental conditions. This experimental study was conducted on a laboratory scale reactor in a semi-batch mode. The effect of critical operating parameters such factors as pH, concentration of ...

Introduction: Ammonia in form of ammonium ions is toxic and could decrease the dissolved oxygen in water and endanger the aquatic life. The aim of this study is the removal of ammonium using oxidation and adsorption by catalytic ozonation and clinoptilolite zeolite, respectively. Methods: The research method is Experimental. First, optimal pH of ammonium adsorption on carbon catalyst (5 g/L), ...

The objective of this work was to analyze the activity of petroleum coke and of activated carbons prepared from this material in the ozonation of aromatic contaminants of low biodegradability. 1,3,6-Naphthalenetrisulphonic acid (NTS) was selected as model compound for the study. The presence of the original coke during 1,3,6-naphthalenetrisulphonic acid ozonation produced a slight increase in t...
