Solar photocatalytic disinfection of real municipal wastewater using highly durable TiO-coated composite in a pilot scale once through reactor.

Pollution of water sources by pathogens is a significant concern worldwide. In the present study, a pilot-scale once-through reactor was fabricated to investigate bacteria's inactivation and the degradation of organic matter present in municipal wastewater using an iron-mediated TiO catalyst in fixed mode. The catalyst was fabricated (in a spherical shape) using waste material such as foundry sand and fly ash and coated with TiO for a combined hybrid effect.

Applications of waste-derived visibly active Fe-TiO composite incorporating the hybrid process of photocatalysis and photo-Fenton for the inactivation of E. coli.

The study reports the applications of waste-derived visibly active Fe-TiO composite for the inactivation of E. coli present in water. The Fe/TiO catalyst holds remarkable properties of in situ hybrid effect via combining the TiO-photocatalytic and photo-Fenton process in one system causing increased production of OH˚.

Dimensionally stable anode (Doped-MMO) mediated electro-oxidation and multi-response optimization study for remediation of urea wastewater.

In the present study, the potential application of novel doped-MMO (Ti/IrO/TaO/SnO-SbO) anodes as an alternative source to costly electrodes have been visualized for the EO treatment of urea. Parametric optimization for the treatment of urea through the EO process by doped-MMO has been done successfully. The high R values of both responses i.

Degradation of pharmaceutical drug paracetamol via UV irradiation using Fe-TiO composite photocatalyst: statistical analysis and parametric optimization.

In the present investigation, a novel Fe-TiO composite was fabricated by mixing fly ash (FA), foundry sand (FS), and bentonite clay for the degradation of paracetamol (PCM). This composite acts as a surface for immobilizing the TiO catalyst (using the dip-coating method) besides facilitating the leaching of iron (FA and FS) in acidic conditions. Leached iron (in the form of Fe(II), Fe(III), and total iron) promotes the photo-Fenton (with the addition of HO in the system) while the surface-active TiO layer leads to photocatalysis, thus leading to in situ dual process combining photocatalysis and photo-Fenton in one system.

In-situ dual effect of Ag-Fe-TiO composite for the photocatalytic degradation of Ciprofloxacin in aqueous solution.

Industrial waste materials such as Fly Ash (FA), Foundry Sand (FS) were used as support material by mixing them with clay to fix the catalyst. Where FA and FS served as an iron (Fe) source to induce the photo-Fenton process. The presence of Fe in FA and FS was affirmed by SEM-EDS characterization.
