[ 1 ] - Inactivation of Fecal coliforms during solar and photocatalytic disinfection by zinc oxide (ZnO) nanoparticles in compound parabolic concentrators (CPCs)
Water samples of 0, 50, and 100 nephelometric turbidity units (NTU) spiked with fecal coliforms (107 CFU/ml) were exposed to natural sunshine in 1l quartz glass tubes fitted with rectors’ compound parabolic concentrators CPCS at two forms CPC1 (whit nanoparticle zinc oxide) and CPC2(without nanoparticle zinc oxide). The samples were characterized using the X-ray...
[ 2 ] - Investigation efficiency of nano photocatalytic compound of TiO2 and rice husk silica in removal of reactive red 198 dye from synthetic aqueous solutions
This study was performed with the aim of investigating the efficiency of the Nano photocatalytic of ultraviolet and titanium dioxide compound and rice husk silica adsorbent (UV/TiO2/RHS) in removal reactive red 198 dye from synthetic aqueous solutions. The removal of reactive red 198 dye was done in batch reactors with a volume of 250 ml using RHS deposited by titanium dioxide in the...
[ 3 ] - Occurrence and fate of emerging pollutants of 17beta-estradiol and testosterone in hospital wastewater and effluent: The effect of activated sludge and chlorination processes
Introduction: In 2015, the European Union placed estrogen hormones on the list of compounds with a possible real risk to living organisms and emphasized the need for environmental research. The aim of this study was to determine the occurrence and effect of activated sludge process and chlorination on the fate of 17-beta estradiol and testosterone in hospital wastewater. Materials and Methods: ...
