Photocatalytic inactivation of Clostridium perfringens and coliphages in water
(Brazilian Society of Chemical Engineering, 2003)
Effect of the Radiation Flux on the Photocatalytic Inactivation of Spores of Bacillus Subtilis
(Elsevier Science Sa, 2010-07)
In this paper, the photocatalytic inactivation of dry spores of Bacillus subtilis dispersed on TiO2 films and irradiated with UV-A radiation (2.44–0.29mWcm-2) was studied. Experimental results indicate a minor reduction ...
Photocatalytic inactivation of dairy bacteriophages contained in aerosol: Comparative evaluation of efficiencies
(Elsevier Science SA, 2021-03)
The aim of this work was to investigate the photocatalytic inactivation efficiencies of eight phages infective to lactic acid bacteria (LAB) contained in bioaerosols. Studies were performed in a semi-pilot scale equipment, ...
Inactivation Of Giardia Duodenalis Cysts By Peroxidation And Peroxidation Assisted By Ultraviolet Radiation
(ASSOC BRASILEIRA ENGENHARIA SANITARIA AMBIENTALRIO DE JANEIRO, 2015)
Photocatalytic inactivation of airborne microorganisms. Performance of different TiO2 coatings
(CRC Press - Taylor & Francis Group, 2014)
The quality of indoor air has a fundamental importance for human health. Indoor air pollutants include, among others, biological contaminants present as bioaerosols. The latter are mostly composed of bacterial cells, fungal ...
Photocatalytic paint for fungi growth control under different environmental conditions and irradiation sources
(Elsevier Science Sa, 2018-09)
The fungicide effect employing Aspergillus niger as a representative microorganism was tested applying a Photocatalytic paint formulated with an anatase carbon doped TiO2 and compared with a homemade non-active paint (rutile ...
Photocatalytic inactivation of bioaerosols in a fixed-bed reactor with TiO 2 -coated glass rings
(Royal Society of Chemistry, 2019-01)
The photocatalytic inactivation of Bacillus subtilis spores in air was evaluated employing a fixed-bed reactor with TiO 2 -coated glass rings, under artificial UV-A radiation. Calculations of the radiation effectively ...
Photocatalytic and photoelectrochemical inactivation of Escherichia coli and Staphylococcus aureus
(Iwa Publishing, 2015-01-01)
Water disinfection usually requires expensive chemicals or equipment. Chlorination is a common disinfection method, although it is not able to inactivate all pathogens. High concentrations of residual chlorine also cause ...
Gas phase photocatalytic bacteria inactivation using metal modified TiO2 catalysts
(2013-02-01)
The present study describes the efficiency of heterogeneous photocatalytic reactor for the inactivation of three air born bacteria, Escherichia coli, Bacillus subtilis and Staphylococcus aureus using metal modified TiO2 ...
