Uv-led Irradiation Technology for Point-of-use Water Disinfection in Developing Communities
Ultraviolet (UV) irradiation is a common disinfection option for water treatment in the developed world. There are a few systems installed in developing countries for point-of-use treatment, but the low-pressure mercury lamps currently used as the UV irradiation source, have a number of sustainability issues including a short lifetime of approximately one year and toxic mercury inside that must...
متن کاملModelling the Kinetic of UV Water Disinfection
Ultraviolet disinfection is an attractive tool for treating water and eliminating pathogens with safe and available technology especially in developing countries where waterborne diseases cause the death of thousands of people every year. Even though UV is an easy tool to perform disinfection, concerns over the potential of microorganism reactivation constitute an issue for its development. In ...

متن کاملImpacts of goethite particles on UV disinfection of drinking water.
A unique association between bacterial cells and small goethite particles (approximately 0.2 by 2 microm) protected Escherichia coli and Pseudomonas putida from UV inactivation. The protection increased with the particle concentration in the turbidity range of 1 to 50 nephelometric turbidity units and with the bacterium-particle attachment time prior to UV irradiation. The lower degree of bacte...
متن کاملDisinfection by-product formation of UV treated swimming pool water
Water samples from 3 indoor swimming pool facilities were tested to evaluate UV-induced effects on swimming pool water chemistry. Concentration change of several DBPs was investigated in experiments including medium pressure UV treatment with and without chlorine and post-UV chlorination. Post-UV chlorine consumption increased, dose-dependently, with UV treatment dose. A clear absence of trihal...
