Decolorization and biodegradability of a real pharmaceutical wastewater treated by H2O2-assisted photoelectrocatalysis on TiO2 meshes

Decolorization kinetics and mass transfer mechanisms of Remazol Brilliant Blue R dye mediated by different fungi

“…The decolorization of RBBR dye by the various methods of physical, chemical and combined physicochemical treatments have many disadvantages and limitations [ 7 , 8 ]. Photoelectrocatalysis combined with a single-step H 2 O 2 dosage on TiO 2 meshes has an effective configuration optimizing with a low energy cost for the decolorization and biodegradability of RBBR dye from a pharmaceutical wastewater [ 9 ]. Biological based methods for the RBBR degradation could be more environmentally friendly than chemical and physical methods due to the use of biological reductant may result in the formation of nonhazardous bioproduct and lowers the energy requirements [ 10 , 11 ].…”

Single‐Step Preparation of Large Area TiO2 Photoelectrodes for Water Splitting

“…Owing to its nontoxicity, low cost, good chemical stability, and band energy levels suitable for excitation under UV–vis irradiation, titanium dioxide and its doped variants are considered among the most viable electrode materials for photocatalytic applications, such as water and air depollution, water splitting and CO 2 reduction. [ 1–8 ] Out of all techniques for the growth of thin films for photoelectrodes preparation, [ 9–11 ] Plasma Electrolytic Oxidation (PEO) allows to easily synthesize photoactive TiO 2 layers with tuned crystalline phase composition [ 12–14 ] and dosage of doping elements. [ 15–21 ]…”

Horizontal Flow Constructed Wetland for Greywater Treatment and Reuse: An Experimental Case

“…In addition to reducing water consumption, a possible solution can be the reuse of treated wastewater (WW) produced by human activities [15][16][17]. The WW presents a very large number of contaminants such as dyes, surfactants, heavy metals, drugs, personal care products and bacteria [18][19][20][21][22][23]. To date, there are numerous treatments to remove the contaminants present in the WW, but there is still little attention to the possible reuse of treated water.…”
