Removal of methylene blue dye from simulated wastewater by cement kiln dust

The purpose from testing studies to discovery out the efficiency of CKD from Al-Muthana city Iraq government to removal Methylene Blue Dye (MB) in simulated textile wastewater generated from Al-Diwaniyah textile factory in Al-Diwaniyah city Iraq government. The wastewater discharge from textile industries that contain methylene blue dye is removed by adsorption through cement kiln dust, therefore, was studied this case. The best electrostatic action is the basic action between methylene blue and cement kiln dust. As cement kiln dust has especially nanostructure properties and the negative charge for his plane, the positive charge for methylene blue compound ability for simply adsorb above it. The optimum condition for gain the best removal of dyes and reach to 99.57% it is initial concentration 10 ppm, pH 9.0, temperature 30 C, dosage 1 gm and rotary speed 150 rpm.The reason for this may be due to synergy effect of both pH value of the media and the basic effect from the melting of the added adsorbent material in the media in addition to the presence of additional exchange sites when increase the dose of adsorbent.
