استعمال أطيان الأتابلغايت المحلية في تنقية الكيروسين الملوث من العناصر الثقيلة

الملخص EN

The objective of the present work is to treat the wastewater of Al-Ahbar factory that belongs to (That AL-Sawari Co.

for chemical industries) by using local Attapulgite clays and recycling ability of this wastewater after treatment.

To achieve that it has been done (90) experiments on the wastewater to determine the efficiency of the local attapulgite clays in the treatment of factory wastewater which has high concentrations of heavy metals (Co, Cr, Cu, Fe, Mn, Ni, Ti and Zn), consisting of Kerosene as a base material using in the washing of inks residue.

The experiments had proved the efficiency of the local attapulgite clays in the treatment of wastewater.

It is necessary to mention that this is the first time of using attapulgite clays in the treatment of wastewater (Kerosene based).

This clays have high efficiency in purification of the factory waste from heavy metals more than (90%) while the concentrations of the heavy metals decreased in that waste after treatment by attapulgite clays and it becomes even less than in kerosene before using in washing of inks residue, the testing of kerosene has shown the possibility of reusing the kerosene after it’s purification from heavy metals and using it in the washing of inks residue
