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

14 Перейти на первую страницу 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, mm of grain sizes Column bed: L = 350 mm, S= 2950 mm 2, BV = 1 liter. Independent tests performed by the "ECOSOFT" JSC, Kiev, Ukraine Flow rate, bed volumes per hour (BV/h) (BV) Bed Volumes of purified water Fe-content in a filtrate, mg/l рН 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 Перейти на первую страницу Decontamination of drinking water from arsenics Mounting spring water fro the North Caucasus region Initial As -content: mg/l (64  g/l), TDS=0.43 g/l. Flow rate, bed volumes per hour (BV/h) (BV) Bed Volumes of purified water As-content in a filtrate,  g/l (5 liters)

16 Перейти на первую страницу ARSENICS PROBLEM IN THE WORLD 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 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. 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.”

20 Перейти на первую страницу Illustration of the Main Idea by an Actual Example Argentina, Underground water

21 Перейти на первую страницу 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 Pretreatment RO Relation of flow rates (9 : 1) is chosen referring to the main (10-times) contaminator - As Initial flow flow rate =1.00 By-pass flow rate = 0.11 Pure water 1.1 units

22 Перейти на первую страницу 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. SCOV RO Relation of flow rates (1.3 : 1) is chosen referring to minor (2.5-times) contaminator – Sulphates.`The productivity grows extremely. Initial flow Flow rate =1.00 Bypass flow rate = 0.65 Pure water, 1.65 units
