  • Abstract This study was to develop a high efficiency and low cost modified diatomite absorbent for copper removal from wastewater. The diatomite was modified and activated by three ways, which were acid etching, alkaline etching and iron hydroxide coating. According to the results of isotherm adsorption test, the efficiencies of copper adsorption by alkaline etching and iron hydroxide coating diatomite were better than those of acid etching and original diatomite. The adsorption capacity of copper by modified diatomite was fitted to Langmuir adsorption model. After the evaluation of removal efficiency and economic feasibility, alkaline modified diatomite was selected to run column and pilot scale adsorption tests.
    The results of kinetic adsorption test showed that the alkaline modified diatomite could enhance copper adsorption capacity and removal efficiency as compare to that of the original diatomite. The results of laboratory scale column tests revealed that the copper removal efficiency was greater than 98% before 1000 bed volumes of wastewater passed through. The copper removal efficiencies of 65~84% were achieved by pilot scale treatment facility for treating real wastewater containing 3 ppm of copper. Therefore, the utilization of alkaline modified diatomite could further reduce the copper concentration and was feasible to meet the more restricted discharge criteria.
