12. Activated serpentinites New Sorption Materials «SKOV» Patent of Russian Federation: 2316479. European Patent Application (WiPO) : WO/2007/111531 Based on: natural hydrocilicatemagnisian. «Radiy» holds a mining licence for 50million tuns of the mineral. Worlds best known matirial for removing metal. Similtniasly cleans water from metal, manganese, color and heavy matels, arsenics, fluorine and bromine, and clear up the water. Independent test have been carried out in diferent countries Possesses by bactericidal properties

13. Results of independent tests

14. Removal of iron from brackish well water in cyclic processes: sorption-back washing. Initial Fe -content: 6.1 mg/l, TDS=4.9 g/l (Total mineralization). Sorption material - granulated SKOV, 1-1.5 mm of grain sizes Column bed: L = 350 mm, S= 2950 mm2 , BV = 1 liter. Independent tests performed by the "ECOSOFT" JSC, Kiev, Ukraine The sensitivity of the purification process to flow rate was checked. During the continuous passing initial water trough the sorption bed, the flow rate was kept 10 l/h, then, elevated two times, up to 20 l/h, and then, reduced back.

15. Decontamination of drinking water from arsenics Mounting spring water fro the North Caucasus region Initial As -content: 0.064 mg/l (64 g/l), TDS=0.43 g/l .

16. ARSENICS PROBLEM IN THE WORLD Natural arsenic pollution is a global phenomenon for 70 countries on all continents, except Antarctica,. In recent decades about 140 million people worldwide have been exposed to drinking water containing more than 10 μg/L of arsenic.” WHO's activities on arsenic In 1963 the standard was estimated to be 0.05 mg/L. In 1984, this was maintained as WHO's "Guideline Value"; and many countries have kept this as the national standard or as an interim target. According to the last edition of the WHO Guidelines for Drinking-Water Quality (1993): Inorganic arsenic is a documented human carcinogen. 0.01 mg/L was established as a provisional guideline value for arsenic. Based on health criteria, the guideline value for arsenic in drinking-water would be less than 0.01mg/L.

17. Plants for local water provision (Country houses, Cottages) и дач. Pроизводство в НПП «Радий» c 2009 г. a tipical machine with an aoutput of 240tuns in 24h for a chidrens summer camp in moscow region.

19. 3. Combined sorption-membrane processes

20. Illustration of the Main Idea by an Actual Example Argentina, Underground water

21. The component contents should be reduced:- Total Dissolved Salts (TDS) – in 1.4 times;- sulphates - in 2.5 times- fluorides – in 1,2 times- arsenic – in 10 times Standard technology, for example with the use of Reverse Osmosis (RO) with the productivity of 1 conventional unit Initial flow flow rate =1.00 By-pass flow rate = 0.11 Pure water 1.1 units Pretreatment RO Relation of flow rates (9 : 1) is chosen referring to the main (10-times) contaminator - As

22. Initial flow Flow rate =1.00 Bypass flow rate = 0.65 SCOV Pure water, 1.65 units RO Relation of flow rates (1.3 : 1) is chosen referring to minor (2.5-times) contaminator – Sulphates.`The productivity grows extremely. The component contents should be reduced:- Total Dissolved Salts (TDS) – in 1.4 times;- sulphates - in 2.5 times- fluorides – in 1,2 times- arsenic – in 10 times The distinction of our technology, also with the use of Reverse Osmosis (RO) with the productivity equal 1 unit, is in using SKOV for pretreatment for disironing andfor removal arsenic.
