The MO-50000 system of water treatment, storage of water and water supply is designed for water purification of open reservoirs and wells from suspensions, colloids, disinfection from bacteria and viruses, including spore combat forms of biological agents, neutralization of highly toxic organic and inorganic substances, including combat toxic agents, deactivation of radioactive substances, removal of the compounds of iron, manganese, copper, sulfur, phosphorus, organic matters, including oil products, and dissolved salts, including the compounds of univalent, bivalent and polyvalent metals as well as for storage and delivery of the purified water under pressure to the consumer's main.

The system is designed for water purification in case of a pollution of the water intake with radioactive, toxic and bacteriological agents due to diversions, anthropogenic and natural disasters. The nominal throughput capacity of the system is 50 m3/h (1,200 m3/day), which is sufficient to provide:

  • 4,800 people according to the consumption rate established for urban people (250 l/person in day);
  • 15,000 people according to the consumption rate established for the military personnel of the APL-500 autonomous field camp (80 l/person in day);
  • 240,000 people when using water only for drinking and culinary.

The delivered system is fully ready for operation. It has the consumable, the set of instruments and the spare parts. The setup time is 6 h. The system consists of five 20-foot olive-green containers of 1C type connected between them by hydraulic and electrical communications:

  • Container N1 — the block for storage for source water;
  • Container N2 — the block of water treatment by ozone;
  • Container N3 — the block of mechanical filtration and preliminary sorption;
  • Container N4 — the block of microfiltration, final sorption and nanofiltration;
  • Container N5 — the block for storage and delivery of purified water.

Operability of the containers at extremely low and high temperatures is provided by the use of seamless fiber ceramics thermal insulation, between the blocks of which there are not convective cavities.

The covering of the containers is completely welded. The connections with gaps (bolted, riveted) are not used. The external surfaces of the containers are subjected to phosphatization before priming.

The system may be completed with the soft reservoirs of MR-NT series for drinking water of 100 м3 volume each used as the blocks for storage of source and purified water instead of the containers N 1 and N 5 as an option.

Technology of water purification

A source water comes to the container N1 where a water-supply is generated in case of cut-off of water delivery from the water intake. A source of the container N1 is pumped over to the container N2, where it is treated by ozone of high concentration (no less than 9 mass %) in two-zone counter-flow reactor. Ozone is produced in the high-voltage high-frequency generators of barrier discharge. A high concentration of ozone is achieved due to the use of the special technology of high-efficient cooling of the high-voltage electrodes (anodes) of the generators. Oxygen of a concentration no less than 95% produced in the oxygen concentrators being in the water treatment system is used as initial gas to obtain ozone. To increase a service time of the molecular sieves of the oxygen concentrators, an air coming to the concentrators is filtrated and dried.

The complete water disinfection from bacteria and viruses, including sporous forms of combat biological agents, oxidation of the compounds of polyvalent metals and semimetals (iron, manganese, copper, cobalt, mercury, bismuth, thallium, arsenic, antimony, etc.) for conversion into insoluble state as well as the complete or partial fracture of the organic compounds (including complex organophosphorous, chloroorganic and arsenic compounds) occur in the two-region counter-flow reactor. After processing by ozone in the reactor the organic compounds are turned to the harmless substances (H2O, CO2), or subjected to a partial destruction with the formation of less toxic and readily sorbate intermediate compounds.

Then a water comes to the container N3 for treatment, where the suspensions formed in water during oxidation in the container N2 are removed in the automatically flushing filters. A preliminary sorption of the products of a partial destruction of the organic compounds, formed during oxidation in the container N2, on activated carbons and a destruction of the residual dissolved ozone take place.

Then a water comes to the container N4 for treatment, where the water microfiltration with a removal of the residual hyperfine suspensions and the final sorption in the ANM material, which is capable to sorb the dissolved substances at a concentration inaccessible for a sorption on active carbons, take place.

The water fully purified from suspensions and dissolved organic compound comes to the nanofiltering membrane cases, where it is separated into the desalted permeate (purified water) and the super-salt concentrate by the membranes. The concentrate is wasted in sewerage.

To increase an interflushing service life of the nanofiltration membranes, a water is dosed with antiscalant before nanofiltration.

The purified water passes through the water counter, is provided with a dose of sodium hypochlorite and comes to the storage tank of the container N5.

The purified water under pressure from the container N5 is pumped in the consumer’s main. The design of the water distributing unit allows for the connection of the system to the available water supply systems with the high-lift pumps, the water delivery to the consumers without connection to mains (in tanks), the water supply of the consumers by temporary pipelines when using the system pumps for injection of the purified water.
