Urban Wastewater Treatment by Adsorption of Organic Matters on Modified Bentonite by (Iron-Aluminum)

Textile Wastewater Treatment by Electrocoagulation Process using Aluminum Electrodes

Background and purpose: Textile industries are among the most polluting industries regarding the volume and the complexity of treatment of its effluents discharge. This study investigated the efficiency of electrocoagulation process using aluminum electrodes in basic red 18 dye removal from aqueous solutions. Materials and Methods: This study was performed in a bipolar batch reactor with ...

Petrochemical wastewater treatment by modified electro-Fenton process with nano iron particles

Petrochemical manufacturing wastewaters often contain a high concentration of biodegradable com-pounds that possess either toxicity or activity inhibition to the biological unit. In this paper, COD removal from Petrochemical wastewaters by electro-Fenton process was studied. The effect of operating conditions such as reaction time, current density, pH, H2O2/Fe2+ molar ratio, and H2O2 of petroch...

Removal of Organic Pollutant from Water by Modified Bentonite

Adsorption Characterization for Multi-Component Organic Matters by Titanium Oxide (TiO2) in Wastewater

In this study, an experimental and analytical study on adsorption and adsorption kinetics of organic matters in titanium oxide (TiO2, Degussa P25) with synthetic wastewater was investigated. In order to understand the removal of different organic sizes in detail molecular weight (MW) distribution of organics matters was examined in terms of number and weight-average MW. The large MW (33950 dalt...

Adsorption of Anionic Dyes on Poly(N-vinylpyrrolidone) Modified Bentonite

A composite based on poly(N-vinylpyrrolidone) (PVP) and sodium bentonite was prepared by a simple method. Structural characterizations of the bentonite and the composite were performed by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and thermogravimetric analysis (TGA). The TGA analysis showed a low loading of the polymer in the bentonite. XRD analysis confirmed a mod...
