The Treatment Efficiency of the Oxidation/Settling Ponds in the Passive Mine Water Treatment Systems in South Korea
Sangwoo Ji , Youngwook Cheong, Giljae Yim, Kyeongjo Kim and Hyunsung Park
Abstract : The analyses of the status and efficiencies of ten oxidation/settling ponds at the passive treatment systems were performed to evaluate the relationship between the efficiencies of iron removal and the structure of oxidation/settling ponds. Four facilities of Hwangji-Youchang, Seokkong-Sinseung, Dongyang OP1 and OP2 among ten ponds have some structures for aerating mine waters. Compared with the guideline of PIRAMID, oxidation/settling ponds of Waryong, Donghae 7th, Seokbong and Honam were evaluated as smaller in size than the guideline. Iron removal efficiencies of oxidation/settling ponds were 1.80% (Waryong) ~ 98.10%
Seokkong-Sinseung). In cases of the Hwangji-Youchang, Gapjeong, Seokbong, Seokkong-Sinseung and Dongyang, the contribution of their oxidation/settling ponds to the iron removal of whole systems was more than 50%.
At the compare with the Hydraulic retention time (HRT) and iron removal efficiency of oxidation/settling pond, ponds which the HRT were less than 40 hours showed the iron removal efficiency less than 50% except Gapjeong.
It means that the iron removal strongly depended on HRT. The efficiency of the oxidation of ferrous and iron removal showed limited efficiencies if mine waters with around pH 3 had been stayed in ponds for a couple of days
Key words : Passive treatment system, Oxidation/settling pond, SAPS, Hydraulic retention time (HRT), Iron removal ratio
