Abstract
As industrial development and expanding population result in increased water recycling in Georgia, effective
water treatment is becoming a higher priority for many communities. Although chlorination procedures are commonly used for disinfecting potable water, the free
chlorine, hydantoins, and isocyanurates employed have brief useful lifetimes in water and can react with organic
impurities to produce trihalomethanes which have been linked to cancer in laboratory animals. Chlorine dioxide and ozone do not provide long-term residuals and being
strong oxiding agents, could react with organic matter in water to produce byproducts of unknown health risks.
Many of the organic and inorganic chloramines lack stability in solid form or in aqueous solutions. (Tsao et al., 1991) Iodination procedures, which are proven water
treatments, depend on compounds which prove toxic to plants thus limiting the recycling capabilities for waste water. Ideally a disinfectant will be stable in solid and
aqueous forms, nontoxic, noncorrosive, tasteless, odorless, and effective against a broad spectrum of organisms (Barnela et al., 196). These qualities are present in the
organic N-halamines described below.
