Abstract

In this study, COD and dye removal from wastewater of textile dying process was investigated. The adsorbents used in treatment experiments produced from domestic and industrials sewage sludge. After chemical activation with 0.5 - 3.0 M ZnCl2 solution, sludge was subjected to pyrolysis treatment at 500°C in order to provide materials has great porosity and high surface area. Textile industry wastewater samples were supplied from dying and finishing process. The pyrolysis treatment test showed that highest specific surface area; 814.48 m2/g could be achieved with the treatment of industrial waste sludge at 2M ZnCl2 solution, thereafter pyrolysis at 500°C. Adsorbents produced at this condition were added into the adsorption and biological activated sludge treatment system to find out the effect of adsorbent addition on the COD and dye removal efficiency. In reactors of treating of textile dying wastewater, COD removal efficiency increased with increasing additive concentrations from 82% to 96%.
