Ultraviolet Germicidal Irradiation and Titanium Dioxide Photocatalyst for Controlling Legionella pneumophila

摘要: Legionella pneumophila , a causative agent of Legionnaires disease and Pontiac fever, is an important microbe to be addressed. Total recovery rates were evaluated in chamber by three sampling methods: AGI-30 impinger, impactor, nuclepore filtration elution. Our results demonstrated that impingers are likely perform better than impaction methods. These might related the stronger stress from dehydration filtration. With regard control techniques, ultraviolet germicidal irradiation (UVGI) titanium dioxide photocatalyst (PCO) considered promising inactivate . In this investigation, influences UV dosage relative humidity on UVGI effectiveness face velocity (TiO 2 ) coating filters laboratory test chamber. It was indicated very low 289 860 w W sec...
