Comparison of methods of enumerating coliforms after UV disinfection.
In view of the differences that have been found between the most-probable-number and membrane filtration methods for the recovery of coliforms from chlorinated samples, the survival of total and fecal coliforms in UV-irradiated effluent samples, as tested by the most-probable-number and standard single-step membrane filtration methods, was compared. There were no significant differences in the ...

ultraviolet radiation (uvr) has been accepted as an attractive alternative to chlorination for the disinfection of wastewater. in this study the effluent from sahebgaranieh treatment plant was subjected to changes in uv transmission and turbidity in order to correlate these commonly measured parameters with the performance of a submerged -uv- reactor employed in disinfecting the effluent. studi...
متن کاملUv 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...
متن کاملDisinfection of Primary Municipal Wastewater Effluents Using Continuous UV and Ozone Treatment
UV radiation and ozonation were investigated as disinfection alternatives for the wastewater treatment plant. The inactivation of total and fecal coliforms using ozone and ultraviolet radiation as separate treatments was evaluated. Different ozone concentrations (3 to 40 mg O3/L) were applied and UV fluencies ranging from 8.5 to 12 mJ/cm at different pH values (from 5 to 9) were tested. Best re...
