| Research Abstract |
In this study, it was investigated that the removal characteristics of tetrachloroethlene and herbicides using coalescing filtration.
The results are obtained as follows :
1.The adsorption isotherm of adsorbant treated with n-hexane is approximated by the Freundlich equation. However, the values, k and 1/n of the adsorbant are lower than those of activated carbon.
2.After the column experiment using upward flow, it was confirmed that the formation of the coalescence of tetrachloroethylene was at the bottom of the column.
3.The adsorption tests using poly propyrene polimer particles treated with n-hexane showed that water solubility of the herbicides is related to the efficiency of the removal rate. Humic acids were not adsorbed on this type of polimer particles.
As described above, nonpolar micropollutants such as tetrachloroethylene and herbicides in the waste water are removed using coalescing filtration.
