Clearing of iron of underground waters. To the Earth the general supply of water make up 1,5 mln. cube kma., bout 2% of this bulk comprises the fresh water, but the amount of the accessible water for using doesn't exceed 0,003%. The available fresh water resourses (rivers, lakes, artificial storage lakes) are apportioned very irregularity. That is why 60%square of the continents of our planet are short of fresh water. The lack of drinking water is observed sharply in 43 countries of the world. In the conditions of rising water pollution of vital activity human being products and very fast rise of water consumption "water hunger" acquire more and more acuity. We offer the new approach for solving all the problems about the water supply of the concerns and people on the basis of the inculcation of economically and ecological advantageous decentralized system (local) for cleaning and disinfection of drinking water. We offer the project, including the whole complex of works forboring and the arrangement of the bore-hole, for cleaning and disinfection of the underground drinking water though the use of the station "Надежда-М" . For industrial enterprises to have their own water-supply system is more economically profitable in 5-10 times, than the employing of drinking water from the centralized water-supply system. The stations "Надежда-М" have the collection of the modifications, securing the cleaning and disinfection of drinking waters from 50 to 1000 cube.m. in day. The stations include the constructive complete modules. The modularity let made the assembling and link up this station to the water-supply system, electric power supply, sewerage with minimal expenditure and in the shortest time. The module collection let make use of station "Надежда-М" widely as for pretty consumers, who don't have the water treatment system, and in the urban networks mounting directly before the consumer, for exception not only the general pollution but the second pollution. The technology of cleaning and disinfection include only the ecologically clean technologies: aeration, degassing, electric-pulse machining, filtering, sorption, ozonization, without reagent, utilization of the pollutants etc. The stations "Надежда-М" expect each employing the reagents, the technologies of processing let cut down expenses of the initial water for own needs. The control system are built on the high technological level with use of contactless systems of engaping/turning of the executive devices, the computer control and bond, the new apparatus for controlling. The presence of the inside computer secure the full diagnostics of the all devices work, state analysis of the station, retraining duties, automatic conditions of work in emergency situations and etc.
The guaranted efficiency of cleaning and disinfection of water, high reliability and steadiness, long lifetime, minimal operating expenditures are obtained at the expense of:- Employing only the ecologically clean high-performance technological process;
- New design decisions
- Special materials.
The technological plan of the station "Nadejda-M" assure:- Multistage cleaning of the sources water;
- Utilization of the pollutants of source water (Up to solid sediment);
- Repeated utilization of the washing water (without discharge into sewerage).
All the used materials, technological and design developments correspond to СНИП (building norms and rules) and another regulating documents.
The high science-technical level is confirmed:- Certificates (are gave by State sanitary epidemiological inspectors of Russia):
Hygienic cert. N 024 from 09.06.95 Hygienic cert. N 070 TC 12 515p 00238 C8 From 26.08.1998 - Technical conditions (are registered in State standard department of Russia)
TY 0130-001-36292685-95 On its level the station "Надежда-М" doesn't yield to the best foreign analogs on the degree of cleaning, and on the cost is well below (Germany, France, Japan at etc).
