摘要： Group of inventions relates to multilayer filtration materials for liquid or gas purification, which can be used purification systems for liquids, for example water from various sources, including drinking water, in ventilation systems or air filtration or for personnel or collective protective equipment production, including respiratory protective equipment, produced based on filtration materials.
Filtration material for liquid or gas purification, consisting of at least two layers, which liquid or gas flows one by one, where first layer is coarse filtration layer and is made on the base of nonwoven fibrous material, and second layer is a fine filtration layer on the base of filtration paper and/or filtration cardboard, characterized in that is configured to sorption filtration of liquid or gas, therein coarse filtration layer contains the particles with size of 2 to 500 mkm, predominantly from 5 to 200 mkm, at least of one type of sorbent, retained in the structure of nonwoven fibrous material, predominantly due to mechanical forces, and the second fine filtration layer contains particles with e size of 0.05 to 20 mkm, predominantly from 0.2 to 5 mkm of at least one fine-dispersed sorbent, retained in the structure of filtration paper and/or filtration cardboard predominantly due to adhesive forces.
Personal protective equipment made as helmet, consisting of body from predominantly transparent polymeric material with air inlet and outlet, collar from elastic polymeric material, and contains at least one air circulation means, therein air inlet and outlet openings are equipped with filters made of filtration material of the claim 1, therein in the inlet filter coarse filtration layer goes first to the environment, and the outlet filter—second fine layer of the filtration material.

摘要： A liquid purification system with purified water mineralization, which uses predominantly water from various resources. The main problem of existing liquid purification systems, particularly membrane systems, is that during purification process not only dangerous debris (residual oil, pesticides, herbicides, heavy metals, bacteria, viruses, mechanical particles and other) are removed, but even minerals necessary for human (calcium, potassium, magnesium, sodium and other), so mineralization step is needed after purification step to normalize mineral composition. In the state of the art are known liquid purification systems with integral mineralization means and also devices for mineralization, which can be connected to liquid purification systems. The working principle of systems, known in the state of the art, is that purified liquid flows through the vessel with mineralization additive, which is partly dissolved, and the liquid becomes mineralized. The main drawback of the systems known in the state of the art is that due to peculiarities of the dissolving process and/or mineralization additive content it is impossible to control mineralization process, so the mineralization level is minor, and the pH is higher than the permitted value. Liquid purification system containing raw liquid line, liquid purification unit, mineralization unit, purified liquid line is characterized in that, mineralization of liquid is done by controlled dispensing of mineralization solution, obtained by selective raw or drainage liquids or their mixture.
