The proposed technical solution relates to the purification and post-treatment of tap water.

State of the art

A household filter for water purification is known (RU 2040303C1 dated 11/21/1991, IPC class B01D 24/08, B01D 29/58, C02F 1/28, patent holders Alferov Mikhail Yaroslavovich, Kulikov Leonid Borisovich, Barsukov Igor Borisovich, Nikitsky Yuri Dmitrievich), containing a cylindrical body with a bottom and a removable cover, a filter element for mechanical cleaning, made in the form of a layer of non-woven polymer fibers connected at the intersections by autogenous gluing, a filter element for sorption cleaning in the form of mechanically interconnected polymer fibers, between which the sorption load is evenly located. In this case, the ratio of the pores of these elements is 5 1 1 with the ratio of their thicknesses 2 5 1. The filter also has a central drainage pipe and an element for water sterilization containing a corrugated membrane. At the same time, the sorption load is made of natural zeolite, aluminosilicate, activated carbon or synthetic ion-exchange resin, and the microfibers are made of polypropylene, polyethylene or polyamide.

The disadvantage of the above filter is

the complexity of manufacturing, due to the complex design of the product, which leads to the impossibility of mass production of the product;

has a non-standard case size, which affects the limited use;

there is no water purification from heavy metals and bacteria.

The objective of the technical solution is to develop a universal filter cartridge that provides complex water purification, including from hardness salts (scale), with the possibility of using it with main and flow filtration systems of other manufacturers with a similar standard.

The technical solution to the above problem is achieved by developing a filter cartridge with three stages of water purification with a diverse flow direction, with a frame that strengthens the structure with two covers with a barrier layer and sealing washers, where

the first stage is a solid polymer material,

the second stage is a solid material based on activated carbon,

the third stage - filter loading.

The specified technical solution provides complex water purification with a long service life, due to the use of three stages of water purification.

A variant of the technical solution is possible, where the filter cartridge frame is made with a standard international size of 10SL.

The specified technical solution provides the possibility of using the inventive filter cartridge with main and flow filtration systems from other manufacturers with a similar standard.

A variant of the technical solution is possible, where the filter cartridge cover is made with a barrier layer, where the latter is a non-woven material, for example, but not limited to, polypropylene fiber with different density and / or non-woven material, for example, but not limited to, polyester fiber. The specified technical solution provides the possibility of using a filter load, and also prevents the penetration / removal of small particles of coal.

A variant of the technical solution is possible, where the filtering load of the third stage contains coal and/or fibrous material, including fibrous material, which is polymer fibers based on polyacrylonitrile, including polyuronic acids or their copolymers and/or alginic acid and its derivatives. The specified technical solution provides cleaning from organic contaminants, heavy metals, hardness salts (scale), etc.

Implementation of the technical solution

The proposed technical solution is a cartridge with three purification stages with a perpendicular flow direction, installed in a housing with a lid, where the first flow stage is a solid polymer material. The latter is a microporous ion-exchange polymer with a spatial-globular structure, designed for the complex removal of a wide range of harmful impurities from water: hardness salts; iron, manganese, heavy metals, chlorine, mechanical particles, viruses, bacteria and organic compounds.

In this case, the second stage is made on the basis of a solid material based on activated carbon.

The third stage is a filter bed, made in the combination necessary for the removal of the required substances. The implemented technical solution works as follows:

Water from the main and / or flow systems enters the first purification stage (2), which is reinforced with a frame (1). Water passes through the first stage of purification, which is a filter material Aragon (2), where it is purified from a wide range of harmful impurities; hardness salts; iron, manganese, heavy metals, chlorine, mechanical particles, viruses, bacteria and organic compounds. Then the filtered water passes through the second stage (3) (SHS), being purified from residual chlorine and organochlorine impurities. After the second stage, the water enters the third purification stage, the filter media (4). At the same time, the filter media (4) additionally purifies or gives the filtered water the specified properties depending on the media used: the catalon is designed to remove cations (copper, cadmium, lead, arsenic) and anions (organic, organochlorine compounds and iron bacteria), high-quality coconut activated carbon is designed for additional removal of residual chlorine and organochlorine impurities from water, alginic acid and its derivatives are designed to remove hardness salts (scale).

To assemble the cartridge from above and below, covers (6) are used, in which a barrier layer (5) and sealing washers (7) are installed, designed to hermetically separate water volumes before and after the filtering stages of the cartridge.

The dimensions of the filter cartridge are selected in such a way that it is possible to use it in combination with other manufacturers with the same standard.

The Applicant has made prototypes of the filter cartridge, which confirm the effectiveness of the removal of microorganisms from the water.

According to several experiments based on the filtration of artificially contaminated ultrapure water, the inventive filter cartridge was able to remove bacterial and viral contamination with the following values (obtained in separate experiments):

Table 1 above shows the volumes of model solutions containing bacteria/viruses and the degree of removal of these viruses/bacteria, expressed as a percentage and a logarithmic ratio.

At the same time, an additional advantage of the claimed technical solution is the removal of heavy metals, the results of the experiment are shown in table 2.

The proposed technical solution, namely the filter cartridge, provides comprehensive water purification, including from heavy metals, viruses/bacteria, with the possibility of using with main and flow filtration systems from other manufacturers with a similar standard.
