Claims (6)

1. The method of purification and desalination of saline natural waters, including the treatment of source water with ozone-containing gas, purification in the filtration zone, acid treatment of purified water with its subsequent filtration and separation of purified acidified water into a concentrate and demineralized water, characterized in that the treatment of the source water with ozone-containing gas lead by mixing the components in the jet mode with the formation of a gas-liquid flow, affect it by a pulsed magnetic field, serves the gas-liquid flow for cleaning in the filter area After passing it through the contact apparatus and separating the remaining ozone-containing gas at the outlet from the contact apparatus from the purified water supplied to the acid treatment, the separation stage is carried out by spraying purified acidified water to produce drops of 0.1 to 10 microns pulsed flare discharges with obtaining charged drops of concentrate and uncharged drops of desalinated water, removal of desalinated water, separation of electrodes ntrata depending on the values of their charge, followed by withdrawal of the concentrate fractions.  2. The method according to claim 1, characterized in that the mixture of ozone-containing gas with the source water is carried out in a volume ratio of 0.1 - 0.5: 1. 3. The method according to claim 1, characterized in that the frequency of the magnetic field pulses is determined from the ratio
f = V / L,
where V is the velocity of the gas-liquid flow, m / s;
L is the distance traveled by the gas-liquid flow from the beginning of the stage of treatment of the source water with ozone-containing gas to its exit from the filtration zone of the purification stage, m  4. Installation for the purification and desalination of saline natural waters, including an ozonation unit with an ozone generator, a filtration zone, an acid treatment system for purified water with an acid reagent inlet pipe and a filter, and a desalination plant equipped with a demineralized water outlet pipe, a housing and a device installed inside the housing separation of purified acidified water into a concentrate and demineralized water, characterized in that the ozonation unit contains a jet reactor equipped with a pump for supplying source water, with a nozzle and ozone containing gas, an outlet nozzle and an ejector device connected through the I ozone containing gas from the ozone generator tube; means of magnetic impact on the gas-liquid flow, located at the reactor outlet nozzle, connected to the filtering zone located in the ozonation unit, and contact apparatus connected by the inlet to the filtering zone, the outlet to the acid treatment system and equipped with an absorbing nozzle at the outlet of it , and the device for separation includes a high-voltage electrode connected to a pulsed current source, and a lateral n shaped as a hollow truncated cone with retina surface and bottom with lower base connected to the nozzle of the demineralized water; centrifugal atomizer with nozzles installed inside the electrode and connected to the outlet of the acid treatment system; mesh separators installed on the outside of the electrode, and nozzles for the withdrawal of concentrate fractions, located under the respective separators.  5. Installation under item 4, characterized in that the truncated cone of the electrode is made with a generatrix length equal to four distances between the nozzle edge of the centrifugal sprinkler and the side surface of the electrode.  6. Installation according to claim 4, characterized in that the outlet pipe for desalinated water is made of water-insulating insulating material.
