Hybrid Technique For The Waste Water Treatment Using Bio Waste of Tea Plant

Ahmmed Saadi Ibrahim, Khaloued Al-baloushi and Rafiya Musabah Al-alawi

The effect of physical, mechanical and multi – step chemical treatments on the adsorptivity of waste of tea (WOT) adsorbent for the removal of 3 multi – heavy metal component from simulated wastewater was evaluated in this study. There are new techniques of (WOT) adsorbents prepared for the adsorption studies, namely physical treatment of (WOT), mechanical treatment of Blended (WOT) and chemical treatment of (WOT) using different pH ( 2, 4, and 5.5). The fixed bed column study was carried out under multi layered fixed bed columns. It was found that, the adsorption of multi – heavy metal component was significantly increased in the following order: first layer of pH 2 remove Cr, second layer of pH 4 remove Zn and third layer of pH 5.5 remove Cu. The highest percentage reduction of area under the graph was demonstrated by multi pH layers treated (WOT) fixed bed column by 95. This model also exhibited highest adsorption performance.
