Abstract |
The photo catalytic oxidation using TiO_2 with UV light was tested to remove odorous and toxic by-products by algae. Among various kinds of photo catalytic oxidations, rotating disc system with coated TiO_2 on glass surface showed higher-removal efficiency with long term stability. To reduce the retention time of solution, higher rotation speed of disc was needed. 10 ㎍/L of geosmin and 2-MIB, and 4.0 ㎍/L of microcystin-LR were completely oxidized in 90 min and 120 min of the operation, respectively and 80% of 330 ㎍/L of chlorophyll-a was removed in 240 min of the operation. |
