Cheese wastewater treatment through combined coagulation-flocculation and photo-Fenton-like advanced oxidation processes for reuse in irrigation: effect of operational parameters and phytotoxicity assessment.

The present study aims to investigate the efficiency of a combined cheese wastewater treatment approach involving coagulation with ferric chloride coupled with a photo-Fenton-like oxidation process for potential reuse in irrigation. Laboratory-scale tests were conducted, examining the effect of various operational parameters on the treatment process. Specifically, the effects of initial wastewater pH, coagulant dosage, decantation time for the coagulation process, and initial pH, chemical oxygen demand (COD) concentration, and Fe and HO dosages for photo-Fenton-like oxidation were studied.

Incorporation of g-CN nanosheets and CuO nanoparticles on polyester fabric for the dip-catalytic reduction of 4 nitrophenol.

In the present work, we present the preparation of a new emerged heterogeneous catalyst (PE/g-CN/CuO) by in situ deposition of copper oxide nanoparticles (CuO) over the graphitic carbon nitride (g-CN) as the active catalyst and polyester (PE) fabric as the inert support. The synthesized sample (PE/g-CN/CuO) "dip catalyst" was studied by using various analytical techniques (Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), thermogravimetric analysis (TGA), scanning electron microscopy and dispersive X-ray spectroscopy (SEM/EDX), and transmission electron microscopy (TEM). The nanocomposite is utilized as heterogeneous catalysts for the 4-nitrophenol reduction in the presence of NaBH, in aqueous solutions.

Sol-Gel Synthesis of New TiO Ball/Activated Carbon Photocatalyst and Its Application for Degradation of Three Hormones: 17α-EthinylEstradiol, Estrone, and β-Estradiol.

Many approaches have been investigated to eliminate pharmaceuticals in wastewater treatment plants during the last decades. However, a lack of sustainable and efficient solutions exists for the removal of hormones by advanced oxidation processes. The aim of this study was to synthesize and test new photoactive bio composites for the elimination of these molecules in wastewater effluents.

Enhanced photocatalytic activity of hydrozincite-TiO nanocomposite by copper for removal of pharmaceutical pollutant mefenamic acid in aqueous solution.

Nanocomposites based on hydrozincite-TiO and copper-doped HZ-xCu-TiO (x = 0.1; 0.25; 0.

Nanocomposite material from TiO and activated carbon for the removal of pharmaceutical product sulfamethazine by combined adsorption/photocatalysis in aqueous media.

This work was dedicated to the elaboration of new composite materials based on activated carbon and titanium oxide as an ecological solution for the cleaning of water contaminated with pharmaceutical pollutants. Such new composite materials allowed the combining of adsorption and photocatalytic process, which allows a cleaning process that is low cost making them promising materials. The functionalization of the surface of activated carbon (AC) by TiO nanoparticles forms the core of the nanocomposite material.
