TiO2/UV/O3-BAC processes for removing refractory and hazardous pollutants in raw water

A review on photocatalytic ozonation used for the treatment of water and wastewater

“…Similarly, a synergistic effect between oxidation processes and biological treatment was reported by Li et al [64] by adding UVC/TiO 2 to an ozone-BAC (biological activated carbon) oxidation system.…”

Degradation of 2,4-dihydroxibenzoic acid by vacuum UV process in aqueous solution: Kinetic, identification of intermediates and reaction pathway

“…Chemicals enter the aquatic medium in several different ways, either dumped directly, such as industrial effluents, or from wastewater treatment plants that are not efficient enough [1][2][3][4]. Public awareness, intensification of the urban water cycle, increasing indirect reuse of surface waters as a drinking water resource, and increasing number of regulations like the European Water Framework Directive [5], are major reasons to reduce or stop emissions of priority organic pollutants into the water bodies.…”

“…Conventional treatments based on activated sludge do not always provide satisfactory results, especially for industrial wastewater treatment, since many of the organic substances produced by the chemical industry are toxic or resistant to biological treatment [1][2][3][4]. Therefore, in addition to efforts for sourcereduction, new treatments need to be developed and set-up to meet environmental quality standards.…”

Degradation of n-butyl benzyl phthalate using TiO2/UV

“…Several kinds of phthalates were also degraded by this technology [15][16][17][18][19][20][21][22][23][24]. However, no report about BBP degradation by TiO 2 /UV process could be found in the literature.…”
