O-10000 system of water treatment, storage of water and water supply
The 0-10000 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, the compounds of iron, manganese, sulfur, the organic matters, including oil products, as well as for storage and delivery of the purified water under pressure to the consumer's main.
The nominal throughput capacity of the system is 10 m3/h (240 m3/day), which is sufficient to provide:
- 1,000 people according to the consumption rate established for urban people (250 l/person in day);
- 3,000 people according to the consumption rate established for the military personnel of the APL-500 autonomous field camp (80 l/person in day);
- 50,000 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 is the 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.
The system has the following blocks being in the common housing:
- The block for storage for source water;
- The block of water treatment;
- The block for storage of purified water;
- The block of delivery of purified water to the customer’s main.
Technology of water purification
A source water is accumulated in the block for storage of initial water, then it comes to the units of multi-cartridge pre-filters, where it is purified of mechanical impurities and the dissolved organic substances. Then water is pumped 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, 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.
A water from the reactor comes to the input of the pump of a high pressure and is delivered to the automatically flushing filters where the suspensions formed during oxidation are removed. Then a preliminary sorption on activated carbons of the products of a partial destruction of organic compounds formed during oxidation and a destruction of the residual dissolved ozone take place. Then a water comes to the units of the multi-cartridge post-filters, where it is micro-filtered for a removal of the residual hyperfine suspensions. The finishing sorption takes place in the ANM material, which can sorb the dissolved substances at the concentrations inaccessible for a sorption on activated carbons.
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 delivery of a water 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.
