Adsorption of Some Heavy Metals from Sewage Water of Internal Departments for Students in Diyala University

This study focuses on treated sewage water in the internal departments of Diyala University, located in the northeastern part of Baghdad City, Iraq, for treatment utilizing indigenous Attapulgite clay, then releasingit into the waterway. Investigating the use of Attapulgite clay to reduce heavy metal ion concentrations (Fe, Ni, Zn, Pb) and suspended solid particles (SS) in effluent water. In addition to reusing treated sewage water to mitigate the environmental hazards associated with polluted water, further industrial applications for Iraqi clays are being explored. Seventy experiments were carried out on effluent water to evaluate the efficacy of Attapulgite clay in filtering wastewater containing high levels of suspended solids (SS) and heavy metal ions. The study revealed a reduction in the concentrations of the selected heavy metal ions from Fe 18, Pb 1.8, Ni 3.6, and Zn 6 ppm to Fe 1.22, Pb 0.36, Ni 0.295, and Zn 0.674 ppm after the implementation of the therapy. Meanwhile, the SS concentration decreased from 0.92 grammes to 0.03 grammes after the aforementioned treatment. The current investigation has produced findings that demonstrate a decrease in clay content and time required for processing.
