Hydrothermal synthesis of novel heterostructured Ag/TiO2/CuFe2O4 nanocomposite: Characterization, enhanced photocatalytic degradation of methylene blue dye, and efficient antibacterial studies

“…The removal of dyestuff from the wastewater has become immensely important because the dyestuff will cause environmental toxicity and health hazards to the public (Hou et al, 2010) (Wang et al, 2009). Frequently adopted sewage treatment includes biodegradation (Al‐Saedi et al, 2019), physical adsorption (Yang et al, 2018), microwave catalysis (Wang et al, 2019), and photocatalytic degradation (Zhang et al, 2018) (Zhang et al, 2017) (Yang et al, 2016). Among various methods of removal of the dye, photocatalytic degradation has given promising performance in the present scenario for the effective removal of toxic dye emitting from industries.…”

Dynamics of nitrate and nitrite in saturated sand filters with enhanced substrate conditions for denitrifying bacteria

“…The addition of external C sources and internal C sources to the filter material has been considered a stable source of carbon for denitrifying bacteria, potentially enhancing nitrogen removal and reducing the hydraulic retention time and the treatment area required per unit volume of wastewater and thus reducing treatment costs [6][7][8][9]. Ethanol and sucrose have often been the choice in practice as they are cheap and convenient [6,10].…”
