DRINKING WATER PURIFICATION AND CONDITIONING SYSTEM AND A FILTER CHARGE FOR PURIFYING DRINKING WATER

摘要

The invention relates to environmental science, specifically to drinking water purification, and can be used to obtain high-quality drinking water including water suitable for bottling and long-term storage. The proposed purification system is provided with an assembly for pre-purification, primary sorption purification and final purification, based on microfiltration. The filter charge consists of consecutive layers of sorption-filtering materials arranged in series along the direction of flow of the water to be purified. Layer A consists of microfiltration fibres with pores of 1-100 microns in diameter, or a mixture of such fibres with granulated or fibrous sulpho- or carboxyl cationites in Na or Na/H forms, or a mixture of such fibres with granulated or fibrous anionites in OH- or polyiodide forms; or carboxylic or sulpho-cationites in Na or Na/H form or a mixture of those cationites and granulated or fibrous anionites in OH or polyiodide form. Layer B consists of consecutive layers of modified zeolite of monoclinal structure, carboxylic cation exchangers of the BION-KN-1(1M) or KB-ChP-2 type and activated carbon, a part of which is in bactericidal (silver) form. Layer C consists of microfiltration fibres with pores of between 0.5-10 microns in size.
