A water filter with a cryogel containing silver nanoparticles for removing chemical contaminants from water.

Abstract

The utility model relates to the field of water purification, environmental and chemical technology and can be used to remove chemical contaminants from water in domestic and autonomous conditions. The water purification filter is made in the form of a cylindrical body, inside which filter elements are sequentially placed, forming a multi-stage purification system, including a large-mesh mesh for removing mechanical impurities, a fine-mesh mesh for trapping smaller particles, a layer of activated carbon for adsorbing organic pollutants, a layer of sand for additional mechanical filtration, a layer of cryogel modified with silver nanoparticles, A layer of mineral components that improves the water's composition, which performs the primary sorption function, and a protective mesh that prevents the removal of filter materials. Cryogel with silver nanoparticles is a highly porous three-dimensional structure capable of effectively adsorbing dissolved organic matter, heavy metals, and pollutant nanoparticles, while the silver nanoparticles provide additional antimicrobial action. As water passes through the filter, it undergoes a sequential purification process: at the first stage, mechanical impurities are removed, then organic substances and dissolved pollutants are adsorbed, and as it passes through the cryogel with silver nanoparticles, the primary extraction of chemical pollutants and the suppression of microorganisms occurs. The utility model provides highly efficient water purification, comprehensive removal of various types of contaminants, an antimicrobial effect, as well as a simple design and the ability to be used without complex technical devices.
