Description

 The invention relates to the field of water supply, in particular to portable devices for integrated water treatment.

 A known device for water purification, selected as a prototype, consisting of filters for rough and fine water purification, a sorption carbon filter, devices for adding chemicals to water and for desalination of salt water.

 The known device has a very complex scheme using additional devices of anion exchange, electrodialysis, dosing of chemicals for disinfection of water, etc. and therefore its use as a portable, for example, in field water supply is very limited.

 The invention is aimed at improving the convenience and ease of maintenance and the exclusion of chemicals from the water treatment scheme.

 To achieve this, it is equipped with a control valve installed on the discharge line and a two-position valve, an ultrafiltration filter with hollow fibers is used as a pre-filter, a battery of parallel-connected active carbon fabric cartridge elements is used as sorption filters, as sterilizing filters used in series cartridge sterilizing microfilters, and the output for the filtrate from the preliminary filter source is connected in series with sorption and sterilizing filters, while using a two-position valve installed in the first position, on the one hand, the pump and the input of the pre-filter are communicated, and, on the other hand, the output for the concentrate from the pre-filter and the discharge line concentrate or by means of a two-position valve installed in the second position, on the one hand, the pump and the outlet for the concentrate from the pre-filter are communicated, and, on the other hand, the inlet of the pre-filter for cleaning and a concentrate discharge line, the sorption and sterilizing filters being placed on an axially arranged perforated pipe in a common cylindrical body divided by partitions into sections, and the perforated pipe at the junction of the sections is separated by bushings with radial holes, equipped with a plug in the first section and an outlet fitting in last one.

 In FIG. 1 shows a schematic diagram of an installation; in FIG. 2 - a device for the disposal and sterilization of water.

 The installation comprises a supply line with a coarse water filter 1, a pump 2, an ultrafiltration filter 3 for pre-treatment of water with hollow fibers, a two-position valve 4, a concentrate discharge line 5 with a control valve 6, a battery of cartridge sorption elements 7 made of active carbon fabric and connected in series included cartridge sterilizing microfilters 8.

 In the first position of the on-off valve 4, on the one hand, the pump 2 and the inlet 9 of the water pre-filter 3 are communicated, and, on the other hand, through the circulation line 10, the outlet 11 for the concentrate from the water pre-filter and the concentrate discharge line 5.

 In the second position of the on-off valve 4, on the one hand, the pump 2 and the outlet 11 of the water pre-filter 3 are communicated and, on the other hand, the input 9 of the water pre-filter and the concentrate discharge line 5. The output 12 of the filter 3 for pre-treatment of water by a line 13 is connected to a battery of cartridge sorption elements 7, which is backbone 14 connected to the first of the series-connected cartridge sterilizing microfilters 8.

 Cartridge sorption elements 7 and cartridge sterilizing microfilters 8 are placed in a common cylindrical body, consisting of two parts 15 and 16 connected by a nut 17, on an axially located pipe 18. The body and pipe 18 are separated by partitions 19 and 20, as well as bushings 21 and 22 with radial holes 23 into three sections. In the first section with the inlet fitting 24, cartridge sorption elements 7 are placed, and in the second and third sections the cartridge sterilizing microfilters 8. The pipe 18 is equipped with a plug 25 and the outlet fitting 26. Holes are drilled against each cartridge sorption element 7 and the cartridge sterilizing microfilter 8 in the pipe 18 28.

 Installation works as follows.

The source water by the pump 2 through the coarse filter 1 and the on-off valve 4 is fed to the pre-filter 3, where it is divided into the filtrate and concentrate. The concentrate, together with mechanical suspensions, is discharged through the line 10 and the on-off valve 4 to the concentrate discharge line 5. At the same time, its amount is controlled by valve 6. Periodically, for the regeneration of the hollow fibers of the pre-filter 3, the on-off valve 4 is rotated 180 ^° to the second position, and a reverse flow of water is supplied to the hollow fibers of the pre-filter 3.

 The filtrate, which is partially disinfected water, purified from mechanical suspensions, enters through line 13 to a battery of cartridge sorption elements 7, on which dissolved organic substances, including poisons, also radioactive substances, viruses and bacteria of the Escherichia coli group, are removed from it. The final disinfection of water occurs after its purification in series-connected cartridge sterilizing microfilters 8. The purified water through the nozzle 26 is supplied to the consumer.
