In
short, this facility consisted of eight annular thin-film continuous
flow-through reactors connected in series and equipped with a feed
tank and a peristaltic pump (ISM 10785, Ismatec, Glattbrugg,
Switzerland). Each reactor consisted in a low-pressure mercury vapor
lamp (8 W; model TUV 8WT5, Philips, USA), enclosed in a quartz tube
(20 mm of outer diameter) with an annular treatment gap of 2.5 mm,
thereby allowing the continuous flow of treatment liquids at 8.5 L/h.
