| Abstract |
| In case of Mongolia, even though awareness of the water environment is gradually increased, it is not easy to receive the supply of clean water due to the shortage of water treatment facilities and specialized personnel aging. In addition, ground water quality is also poor with lots of mineral contents including hazardous heavy metal ions. Thus, small-scale water treatment package system, which has considered to design high work performance, portability, low cost and easy replacement, is consist of adsorbent module using alum sludge and zeolite. In this study, batch adsorption tests were conducted using alum sludge and zeolite with heavy metal ions such as arsenic, iron and manganese in order to evaluate applicability in the package system. In the results of experiment, although there are differences of removal rate in accordance with the substance, alum sludge hold great potential to remove cationic and anionic heavy metal species simultaneously with zeolite. Thus, when it applies to small scale water treatment package system in Mongolia, it is able to remove hazardous heavy metal ions effectively. |
