Abstract
A method for disinfecting and purifying tap water and untreated water using a composite, bactericidal adsorption material as a filter. The method provides efficient and reliable disinfection, with simultaneous purification of water from heavy metal ions and organic matter and improvement of taste and odor. Water is filtered through a composite material containing granules of iodinated anion-exchange resin, granulated activated carbon and silver containing adsorbent, all uniformly distributed between amphoteric fibers. The exterior surface area of the iodine containing anion-exchange resin granules is not more than 1% of the exterior surface area of the amphoteric fibers, and the equivalent content of silver exceeds the equivalent content of iodine.
