The MO-4000 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 combat spore forms of biological agents, neutralization of highly toxic organic and inorganic matters, 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 MO-4000 system of water treatment, storage of water and water supply

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 4.2 m3/h (100 m3/day), which is sufficient to provide:

  • 400 people according to the consumption rate established for urban people (250 l/person in day);
  • 1,250 people according to the consumption rate established for the military personnel of the APL-500 autonomous field camp (80 l/person in day);
  • 20,000 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 2 h.

The system consists of the following blocks being in the common housing: the block for storage of source water, the block of water treatment, the block for storage of the purified water, the block for delivery of the purified water in the consumer's main. The system is a 20-foot olive-green container of 1C type.

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.

Thecnology of water purification

A source water is accumulated in the block for storage of a source water, then it comes to the multicartridge prefilter units, where it is purified of mechanical impurities and dissolved organic matters. Then a water is delivered in the two-region counter-flow reactor for processing by ozone of a high concentration (no less than 9 mass %).

Ozone is produced in the high-voltage high-frequency generators of barrier discharge. A high concentration of ozone is reached due to the use of the special technology of highly effective cooling of the high-voltage electrodes (anodes) of the generators.

Oxygen with a concentration no less than 95%, produced in the oxygen concentrators of the water treatment system, is used as initial gas to obtain ozone. To increase a service life 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 a 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.

From the reactor a water comes to the input of the pump of a high pressure, and then it is delivered under pressure for treatment. A water comes to the units of the multi-cartridge post-filters, where it is purified of the mechanical impurities, formed during oxidation by ozone, and the remains of the dissolved organic matters in the ANM material. Here too a destruction of the ozone dissolved in a water takes place.

Then the purified water comes to the nanofiltration membrane cases, where it is separated into the desalted permeate and the concentrate enriched with salts by the membranes. The concentrate is removed from the block of the purified water 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 preservative dose of sodium hypochlorite and comes to the tank of the block for storage of the purified water.

The purified water under pressure from the storage tank 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.

For water purification the system consumes an electrical energy up to 1.2 kW·h per 1 m3 of purified water.

Drainage waters of the system are nontoxic, and their water evacuation on a relief and in the natural reservoirs is admissible without additional treatment.

Control of the system can be carried out remotely.

The system is completely automated and does not demand a control from the user.
