A photocatalytic study of a coloured effluent from a wastewater treatment plant was carried out in a pilot plant using compound parabolic collectors (CPC) in order to find out the best conditions for colour removal, since the discharge limit for this parameter is not achieved after conventional wastewater treatment. The interaction between ultraviolet natural radiation and TiO(2) strongly enhan...

BACKGROUND The main objective of this study was to examine the photocatalytic degradation of phenol from laboratory samples and petrochemical industries wastewater under UV radiation by using nanoparticles of titanium dioxide coated on the inner and outer quartz glass tubes. METHOD The first stage of this study was conducted to stabilize the titanium dioxide nanoparticles in anatase crystal p...

results the results showed that the fog amount in input raw sewage in the mwwtp from june 2011 to september 2011 was around 25.5 mg/l and the amount in treated wastewater was about 8.1 mg/l. the fog removal efficiency in this refinery was about 70% and met the environmental standards for the discharge (less than 10 mg/l) (p < 0.05). conclusions the effluent can be discharged to surface waters o...

Photocatalytic degradation is one of the environmentally friendly methods used in treating dye wastewater. In this study, a series MXene/g-C3N4 heterostructure photocatalysts with different loading amounts MXene (1, 4, 8, and 12 wt.%) were successfully synthesized via wet impregnation method their photocatalytic activity was evaluated methylene blue under visible-light irradiation. As such, 1 w...

single crystal zno microrods are deposited on the surface of zn plate through corrosion of zn plate by h2o2, which is a green neutral reagent and easy to transform to h2o and o2. the structure and morphology of the obtained zno microrods were characterized by x-ray diffraction (xrd), scanning electron microscopy (sem), transmission electron microscopy (tem) and electron diffraction. a thermodyn...
