Tube-in-tube membrane photoreactor as a new technology to boost sulfate radical advanced oxidation processes

This work proposes a tube-in-tube membrane photoreactor, operated in a continuous-mode, to boost the efficiency of peroxydisulfate, through the photolytic and photocatalytic processes. This new technology can efficiently facilitate the transportation of PDS to the catalyst surface and water to be treated
