- Abstract
- Brass granular media has the potential to inactivate microbial contaminants and remove metal contaminants from water which would be useful in treating water at the point-of-use. In order to evaluate the feasibility of brass for use in water treatment, experiments were conducted to: (i) characterize the microbial inactivation and copper and lead removal of brass in a batch and column configuration; (ii) determine the influence of the metal ions on the disinfection kinetics. In a batch configuration with mixing, brass was able to inactivate E.coli and MS2 and remove copper and lead from water. The majority of the microbial inactivation from brass was found to be attributed to the presence of brass media itself and not the ions released into solution. In a column configuration, E. coli, MS2 and lead removal were low (0.5 Log10, 0.5 Log10 and 20% respectively); however copper removal was >95%.
