The present study evaluates the removal of micropollutants from water/wastewater contaminated sources through application a heterogeneous catalytic ozonation process, using pilot-scale continuous operation unit, composed membrane module for diffusion and effective dilution ozone into liquid phase to be treated plug flow reactor/continuous stirred tank reactor (PFR/CSTR) contact system in series...
In this research, the efficiency of catalytic activity iron and manganese-loaded (bimetallic) sodium zeolite was investigated for ozonation-based removal disperse yellow 42 dye. The impregnation method used to deposit Fe Mn on surface zeolite. morphological analysis before after deposition conducted by SEM, EDX, FTIR. It found that several variables, including ozone dose, contact time, pH, cata...
A general overview on the prospective of various oxidation and combined processes in the treatment of tannery industry effluent are reported. Various oxidation and combined processes such as UV/H2O2/Hypochlorites, Fenton and Electro-oxidation, photo-chemical, photo-catalytic, electro-catalytic oxidation, wet air oxidation, ozonation, biological followed by ozone/UV/ H2O2, coagulation or electro...
Background and purpose: 2, 4-dinitrophenol (DNP) are carcinogenic and non-biodegradable pollutants that exist at high concentration in wastewater of chemical industries. In this study, treatment and removal of organic materials (COD) in wastewater was carried out by catalytic ozonation process (COP) using carbon Nano-composite catalysts. Materials and methods: This study was conducted in cyl...
Magnetically separable MgFe2O4 was synthesized and used in catalytical ozonation of 4-chlorophenol (4-CP). The prepared catalyst was characterized by X-Ray Diffraction (XRD), Field Emission Scanning Electronic Microscopy (FE-SEM), Transmission Electron Microscopy (TEM), Brunauer−Emmett−Teller (BET) and Vibrating-Sample Magnetometer (VSM). The optimum conditions for the hig...
Background and purpose: Chemical dyes are widely used in textile industries and have harmful effects on the environment. They also contain carcinogenic and mutagenic substances. The goal of this study was optimization of the catalytic ozonation process using bone char ash modified by magnesium oxide in removal of reactive black 5dye from textile wastewater based on Taguchi design. Materials an...
