• Glass fiber velvet and self-luminous textiles are two promising substrates for the immobilization of TiO 2 -based photocatalysts. • The glass fiber velvet demonstrated good photocatalyst attachment and can receive high UVA irradiation but required large working volume. • The self-luminous textile suffered from low irradiation delivered by the internal optical fibers, but exhibited high flexibility in shape. • A side-by-side combination of the two substrates was implemented in an annular flow reactor without the need for volume expansion. • Efficient degradation of multiple pharmaceuticals in real effluent despite high organic carbon and inorganic ions presences. The release of active pharmaceutical ingredients (APIs) in natural environment has become a global issue. Used as a complementary remediation solution, the heterogenous photocatalysis is underperformed in terms of operation cost per volume of treated wastewater if the non-immobilized catalyst needs to be recovered. This work has identified two promising substrates for the immobilization of TiO 2 -based photocatalysts, namely a glass fiber velvet and a self-luminous textile. The former demonstrated good catalyst attachment and can receive high irradiation intensity from the external UV lamp but required large working volume in the reactor. While the latter suffered from low irradiation intensity delivered by the internal optical fibers, it exhibited high flexibility in shape. Subsequently, a side-by-side combination ...
