Description

The invention relates to autonomous water supply systems for use in centralized and non-centralized systems, including buildings and premises that do not have access to water resources in accordance with accepted standards, but receive water from village water pipes, wells or wells.

Unfortunately, most of the above sources contain harmful and sometimes hazardous substances. According to official data, in some areas there is a multiple excess of maximum permissible concentrations (MPC) for harmful chemicals, including radioactive ones, and pathogenic flora. Intensive land pollution occurs. Harmful substances dissolve and with streams of water seep into aquifers, moving vast distances from pollution sources. First of all, this applies to the European part of Russia.

At the same time, an increasing part of the population wants to live outside the big cities with the greatest comfort. Most of the known systems do not provide an acceptable quality of water purification even for technical needs. Meanwhile, country houses are more and more saturated with objects of quite expensive household appliances, which, as a result of using untreated or poorly treated water, often unreasonably fail.

Autonomous heating systems are at risk, which also reduces the comfort of living.

Autonomous consumer water systems for particularly pure water are known, which provide for the delivery of water in special containers, use special materials for pipelines (1) and do not have the means to separate water circuits for drinking and other needs, which makes the installation uneconomical.

Autonomous water supply systems are known, which provide for the use of separate water flows for technical purposes and for drinking (2) and also contain means for water purification, however, the known technical solution provides for the presence of special non-standard pipelines, which significantly increases the cost of the system, in addition, the means for filtering used in it do not provide the output of particularly pure water.

Water supply systems are known that have several circuits of a divided water stream in order to use waste water for the needs of plumbing (3), however, the known solution provides for the same treatment of all the water entering the building at the initial stage, and additional circuits are created by additional storage tanks and pipelines,

Closest to the proposed utility model is the water supply system of a residential building (4), which contains a multi-circuit piping system for directing water flows as a system for supplying drinking water, as well as water for technical needs, including a hot water circuit.

Among all the known solutions, there are no solutions allowing to obtain physiologically complete drinking water for boiling, drinking water of the highest quality, as well as to ensure the quality of industrial water for hot heat supply and for irrigation and sanitary needs, which is essential for people living outside the city in the most economical way. It is known that it is unprofitable to use equally expensive water treatment for drinking and technical needs, since drinking water requires no more than 10% of the total water supply.

The technical task of this utility model is to create such a device that allows you to solve the above problems in the most cost-effective, simple and reliable way by creating separate circuits for producing industrial water, water for heating and obtaining physiologically high-quality water of the highest quality in the drinking circuit along with the drinking boiling water.

The essence of the claimed technical solution boils down to the fact that in an autonomous system of water supply and water treatment of a pressure type, designed for installation in individual buildings that have water sources that do not meet standard requirements, containing a set of filters installed at the outlet of the source and at the entrance to the highway and pipelines , the water through which is supplied to the points of consumption, some of the filters are used for pre-treatment, part for the preparation of water for the heating network, part for fine treatment and correction of drinking eve water. In this case, the preliminary cleaning is carried out by installing a block of pre-filters or

filling columns of water treatment, sorption and deferrization in the common line, forming the first purification circuit, for this unit or for part of the filters of this unit, the pipelines are connected in series through the water so that they separate the total flow of water flowing into the lines into separate streams so that each flow flows in its pipeline. In the second circuit, filtering means for desalination and softening are placed in order to prepare water for hot heat supply, while the pipeline in which these means are placed is connected to the main line behind some filters that provide protection against mechanical pollution, sorption and deferrization, and is equipped with a tap to ensure cold water for technical needs The third circuit is designed to produce drinking water, while the means to obtain physiologically complete drinking water can be performed using the use of fine-purification agents: using filtration membranes with pores up to 0.01 μR, track membranes or track membranes with prefilters made of polypropylene-based fabric that form the membrane module in the membrane can also be used for this purpose.

The pre-filter block of a drinking circuit may consist of fine mechanical tertiary treatment, filters to remove residues of dissolved and undissolved iron, pesticides, benzene, oil products, heavy metals. It also provides a bactericidal effect due to pre-introduced into the cartridge of silver in a bound metal form, as well as a sorption cartridge to improve the organoleptic properties of water, these cartridges are installed

sequentially along the course of the water. The following are examples of an integrated three-circuit water treatment system according to the present utility model.

. FIG. 1 shows a general diagram of a device according to this utility model.

Figure 2 - diagram of the third circuit, consisting of two branches of pipelines.

Water comes from a source to the input of a complex three-circuit water treatment system. The source water enters the aeration unit 1 (equipped with a pump or a compressor for pumping oxygen). This is where the first cleaning phase ends. The second cleaning phase begins in block 2, where deferrization takes place - the oxidation of divalent dissolved iron to trivalent and manganese oxides. Particles of ferric iron and manganese are retained in the mass of the filler (e.g. sand). As a filter load, well-known universal fillings and cartridges can be used.

For example, ASG filters (based on polymer-globular structures, etc.), “VDK-IO2”, or “VDK-Fe +”. It is important that their filter loading provide the desired effect, namely:

- iron removal (removal of dissolved iron Fe2 + and undissolved Fe3 +), improving the taste of water;

- pesticides, benzene, petroleum products, heavy metals, etc., improved taste: eliminate the smell of water.

- partial softening (reduction of excessive content of hardness salts;

- bactericidal effect due to active silver. Silver introduced into the material of the cartridge neutralizes the vital activity and

the development of filtered bacteria and, at the same time, does not stand out in purified water, because silver in the cartridge is in a bound metal (indelible form), and it is absolutely safe for health when this occurs reagent-free removal of particles up to 30 microns; water enters the cartridge 3 to filter suspensions up to 5 microns, phase 3. Then, in the fourth phase in column 4, water is softened by removing hardness salts; a multicomponent ion-exchange material regenerated with sodium chloride is used as a filler. The regeneration process of the filler is controlled by the automatic control unit as well as the regeneration process of unit 4. Then, at the fifth stage of purification, the prepared water passes further purification on a grinding cartridge post-filter 5, where post-treatment of suspensions and products of abrasion of the filler is carried out by holding them. The sixth phase of the cleaning is carried out using a device for disinfection, for example, using ultraviolet or other radiation 6. This phase can be excluded. The complex of the above filters is the first circuit of K.I.

Pre-purified from various impurities, the water enters the circuit K. II and K. III. From the pipeline connecting the common highway with the second and third circuit, a branch is made for the intake of cold water, its quality is sufficient to provide technical needs and watering, if necessary.

The second circuit (K. II).

In the circuit of room II, water treatment facilities are placed for use in heating networks, they soften and desalinate the water supplied to household appliances

(washing machine, radiators, dishwasher, etc.)

7th and 8th phase. Pre-prepared water at a universal station is further processed to protect plumbing equipment from scale in a cold water supply system. For hot water supply, a desalination system is used, which prevents the formation of scale on the heating elements of household appliances. Means for softening the water 7 for these purposes can be different: it can be electrolysis or electrodialysis, as well as filters, for example, filling or cartridge type for removing hardness salts with the appropriate load as shown in this example, or electromagnetic, or magnetostrictive, or rotary converters (not shown). At the output of block 7, another block 8 is installed, filtering suspensions up to 5 μm. Then the water enters the boiler 9, after heating - into the shower 10 and the heating system 11. The system regeneration control can be manual or automatic.

.Use of this circuit extends the life of household appliances using hot water and reduces the cost of operation of the water supply system, as it limits the amount of water intended for drinking, thereby prolonging the life of track membranes.

The water pre-prepared at the universal station (primary circuit) is delivered to the third circuit, where it undergoes further purification, correction and structuring using environmentally friendly and safe for human health technologies to obtain physiologically complete

drinking water of the highest quality with the use of fine cleaning agents, such a block of high-tech track membranes by academician Flerov can be used, or from these membranes placed in a polypropylene-based fabric membrane (WATER DOCTOR technology, Patent Eurasia No. 005222) or in the form of an ultrafiltration membrane UF 12. The third circuit consists of two separate water treatment schemes. One of them is designed to produce physiologically complete water for drinking. Another is designed to produce high quality water suitable for drinking after boiling, i.e. for cooking, but can also be used for showers, bathtubs, mini-pools for recreational purposes.

The first circuit of the third circuit includes blocks 13 and 14 installed sequentially through water and representing additionally introduced filtering agents for fine mechanical tertiary treatment and consist of filters for removing residues of dissolved and undissolved iron, pesticides, benzene, oil products, heavy metals, here a bactericidal effect is ensured due to silver previously introduced into the cartridge in the bound metal form — block 13 and sorption cartridge 14 for improving organoleptic properties tv water downstream installed water means for its magnetization 15, magnetized water enters the valve 16 and is suitable for cooking. Means for magnetization can be performed in any known manner either in the form of permanent magnets or variables of any shape and type, creating a magnetic field in the zone of movement of the water stream. In parallel, magnetized water enters the fine-purification unit, made either using track membranes with

membrane prefilters made of polypropylene fabric, forming a membrane module in the membrane or without prefilters 12. The filtrate can be mineralized or additionally magnetized (not shown). The fine-purification unit can be performed on a UF ultrafiltration membrane with pores up to 0 micron. The second or other circuit of the third circuit is formed by a parallel pipeline, in which a preliminary cleaning unit 17-19 is placed, made on three cylindrical cartridges and a final fine cleaning unit 20 on the track membranes of Academician Flerov. The unit is equipped with a tap for filtered water 21 and a tap for regeneration 22 The pre-treatment unit 19 provides final mechanical treatment and consists of filters for the treatment of residues of dissolved and undissolved iron, pesticides, benzene, oil products , heavy metals and organochlorines. The obtained water with drinking properties can be used for recreational purposes for the shower, pool, bath .. This makes the proposed water supply system economical, without depriving users of comfort when using it. The implementation of the drinking water block on the membrane-in-membrane modules, where track membranes and polypropylene-based fabric membranes are used as membranes in combination with a predetermined water treatment system allows to obtain optimal consumer indicators: cost-effectiveness and high quality of the resulting water. The resulting water is excellent for drinking, for various household needs, for hot water consumption and for heating networks.
