This slide presentation outlines results from the AWWA Disinfection Practices Survey. The survey's objectives were to: collect basic information
regarding drinking water utilities' secondary
disinfection practices;
report on what percentage of drinking water utilities
currently use chloramines, chlorine, or no
secondary disinfectant; what percentage
of those utilities not currently using chloramines intend to convert to
chloramines; and, information on current
secondary disinfection practices. Topics covered include: survey design and implementation; response demographics; overview of responses on secondary disinfection practices; geographic location, system size, and primary source water of secondary disinfection practices; percentage of utilities planning to convert to using chloramines and reasons why; target residual concentrations of utilities using chloramines; percentage of utilities experiencing nitrification problems that use chloramines; nitrification control strategies; and, common problems encountered when using chloramines.
