ENHANCED N-HALAMINE BASED WATER TREATMENT METHOD AND DEVICE

摘要

A gravity-fed water treatment system is described that purifies water by inactivating bacteria, protozoa, and viruses. In this system, water is first filtered to remove bacteria and protozoa. This can be accomplished by multiple means, such as ceramic filters containing activated carbon. The filtered water then flows into a purification cartridge housing a purification media, such as the compounds or polymers containing N-halamine described by Worley et al. and Bridges et al. This same purification cartridge also houses an adsorptive media that reduces any residual halogen concentrations in the treated water. The contact quality in the purification media chamber is such that the viral particles are saturated with halogens, becoming irreversibly inactivated.
