Can chloramines be used for cooling tower water disinfection?
Chloramines are not very suitable for cooling tower water disinfection, because these compounds react very slowly with pathogenic microorganisms. Can chloramines be removed from water? Chloramines remain active in the water system for a considerably long period of time. Like other molecules, chloramines contribute to the total amount of dissolved solids in the water. Like chlorine, chloramines are selectively reactive and may have damaging affects when they remain in the water for too long. When chloramines are present, there are usually trace amounts of ammonia and hypochlorite in the water as well. Chloramines are hardly ionic. As a result and because of the low molecular weight, chloramines, mainly monochloramine, are difficult to remove from water by reverse osmosis (RO) or water softening. Boiling and distillation cannot be used either. Substances for chlorine removal cannot be used for the removal of chloramines. Sunlight and aeration may aid chloramine removal. Chloramines can b
