The degradation characteristics of PPCPs commonly found in surface water under UV treatment were examined for 30 kinds of PPCPs using a UV/Lamp1 that emits light at a wavelength of 254 nm and a UV/Lamp2 that emits light at 254 nm and 185 nm in pure water. When a UV dose of some 230 mJ/cm(2) was introduced to the 30 PPCPs, photodegradation rates of about >3%(More)
Photodegradation characteristics of pharmaceuticals and personal care products (PPCPs) and the effectiveness of H(2)O(2) addition for PPCPs photodegradation during UV treatment were examined in this study. Average k (1st order rate constant) value for all the PPCPs investigated increased by a factor of 1.3 by H(2)O(2) addition during UV treatment using(More)
The effectiveness of UV-based processes (UV and UV/H(2)O(2)) for the removal of pharmaceuticals in real wastewater using bench-scale experiment setup with a treatment capacity of 10 m(3)/day was investigated. Forty-one kinds of pharmaceuticals including 12 antibiotics and 10 analgesics were detected in secondary effluent used for tested water. For UV(More)
Ozone (O3)-based processes (O3, O3/H2O2, and O3/UV) were investigated for the removal of pharmaceuticals in real wastewater using a bench-scale experimental setup. An ozone dose of 6 mg/L (contact time = 10 minutes) was found to reduce the concentration of most pharmaceuticals detected in secondary effluent. Caffeine, N,N-Diethyl-meta-toluamide (DEET), and(More)
