photocatalytic disinfection of coliform bacteria using uv/tio2

Photocatalytic Disinfection of Coliform Bacteria Using UV/TiO2.

BACKGROUND There are great interests in photocatalytic oxidation of contaminants using titanium dioxide in recent years. The main objective of this research was to study photocatalytic disinfection of Coliform bacteria as water microbial pollution index using TiO2 and a low pressure UV lamp in a batch reactor. METHODS The polluted water was prepared by adding a colony of Coliform in raw water...

Uv Disinfection of Treated Wastewater Effluent: Influence of Color, Reactivation and Regrowth of Coliform Bacteria

Disinfection is a very important unit process to deactivate coliform bacteria in treated wastewater. However, regrowth potential of coliform bacteria raises human health and safety concerns associated with reuse of treated wastewater in various applications. Both post chlorination and post UV disinfection regrowth have been reported in the literature. In view of increasing use of recycled waste...

Development of a field enhanced photocatalytic device for biocide of coliform bacteria.

A field enhanced flow reactor using bias assisted photocatalysis was developed for bacterial disinfection in lab-synthesized and natural waters. The reactor provided complete inactivation of contaminated waters with flow rates of 50mL/min. The device consisted of titanium dioxide nanotube arrays, with an externally applied bias of up to 6V. Light intensity, applied voltage, background electroly...

Advances in photocatalytic disinfection of bacteria: Development of photocatalysts and mechanisms.

Photocatalysis has attracted worldwide attention due to its potential in solar energy conversion. As a "green" advanced oxidation technology, it has been extensively used for water disinfection and wastewater treatment. This article provides a review of the recent progress in solar energy-induced photocatalytic disinfection of bacteria, focusing on the development of highly efficient photocatal...
