The invention relates to composite materials, and more particular to composite adsorptive materials for purification of liquids, in particular, a drinking water, on the basis of components of a granulated material and a fibrous material. The new composite material for filtering purifying a liquid on the basis of a mixture of components of granulated and fibrous materials comprises volume zones with adjustable density, which zones create the structure of the material, which structure is self-strengthened when a liquid flows in the course of filtration, wherein, said volume zones make the material most part, each zone is created in the form of a interlaced fiber site, which sites are bonded among themselves by separate fibers, and the space within and between said interlaced fiber sites is filled with a granulated material.

Composite material

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.

Method of drinking water disinfection

The present process provides improved means for adsorbing components and for regeneration of a composite adsorption carbon material (CRAC) used for effecting the desired separation using an electrochemical process under conditions wherein the specific volumetric electric conductivity of the CRAC differs from that of the electrolyte employed by not more than one order of magnitude, a specific current density of at least 0.01 ampere per gram of CRAC is employed, and a high degree of regeneration of CRAC from polar and non-polar substances and heavy metal ions is obtained, as well as improved adsorption.
