Product Description

Shungite is a unique natural formation, containing *0% shungite carbon and *0% silicates (in their mass of silica *0%).

Shungite carbon has an amorphous structure, resistant to graphitization, is characterized by high reactivity in thermal processes, high sorption and catalytic properties, electrical conductivity and chemical resistance.

The structure of shungite is unusual. The rock is a composite, the matrix of which forms carbon. In the carbon matrix, highly dispersed (less than *0 μm) silicate particles are uniformly distributed. Contact surface of silicates with carbon more than *0 m2 / g.

Average chemical composition:

SiO₂	TiO₂	Al₂O₃	FeO	MgO	CaO	Na₂O	K₂O	S	C	H₂O_крис
*7,0	0,2	4,3	2,8	1,2	0,3	0,2	1,5	1,5	*8,0	3,0

Shungite properties:

· Density of 2,**2,4 g / cm3

· Porosity up to 5%

· Specific gravity - 1, **2 g / cu. cm

· Compressive strength of ********0 kts / cm3

· Electrical conductivity ***0 sim / m

· Coefficient of thermal conductivity 5 W / m2 oK

· Developed internal surface up to *0 m2 / g

· Adsorption activity:

On phenol *4 mg / g

On thermolysis resins - *0 mg / g

On petroleum products more than *0 mg / g

· Adsorption is active against bactericidal cells, phages, pathogenic saprophytes, etc. Shungite shows the ability to disinfect and purify water from bacteria, spores, protozoa, blue-green algae

Has bactericidal properties.

· Shungite particles, irrespective of their dimensionality, possess bipolar properties. The consequence of this is high adhesion and the ability of shungite to mix without exception with all substances,

According to physical and mechanical properties (strength, abrasion, bulk density) shungite is close to the traditionally used filter material - quartz sand.

· Shungite has a sorption ability to a wide range of organic substances (surfactants, alcohols, resins, pesticides, oil products, etc.).

· Shungite shows specific activity in eliminating particles of a radical nature (chlororganics, dioxins) from water, exceeding the activated carbon by *0 times.

· Removes from the water many metals and nonmetals (copper, iron, manganese, aluminum, zinc, cadmium, lead, tin, arsenic, mercury, chromium), various impurities (nitrates and nitrites),

·. Shungite has catalytic properties that accelerate the oxidation of sorbed organic substances.

It has been proved that with sufficient contact time (1 ÷ 7 hours) of schungite with water containing organic contaminants, shungite exhibits catalytic properties in addition to sorption, with respect to the oxidation of organic substrates (dichloroethane, propanol, butanol, toluene, benzene, chloroform, chlorophenol).

· Shungite has the ability to communicate biological activity and healing properties to water.

The effectiveness of using shungite in water treatment is confirmed by the following factors (from the report of the VODGEO Research Institute):

1. favorable mineral composition of schungite (quartz, complex silicates, globular carbon),

2. Optimum in contact with the aqueous phase by chemical composition (micro- and macroelements),

3. compliance with the requirements of GOST "Granular filtering materials":

- chemical resistance in non-aggressive model solutions;

- mechanical strength (abrasion and grinding);

- by the total specific efficiency of natural radionuclides;

- On the optimal values for filter loads of water supply values (density, intergranular porosity, coefficient of heterogeneity of charges, equivalent grain diameters;

-by sanitary-hygienic criteria.

4. Shungite loadings on mechanical properties are close to quartz sand, but they have a sufficiently high intergranular porosity, which causes less head loss and a longer filter cycle (the recommended rate of loosening of the schungite load (fraction 0.**2.5 mm) at ****0% Expansion of layers - ****0 l / sq.cm;

5. Shungite showed a high degree of purification from iron compounds, aluminum (*****0%);

6. In comparison with traditional filtering loads (quartz sand, expanded clay, AU, zeolite, etc.), shungite loads are characterized by a high rate of formation of the operating oxide iron film on the loading surface due to its large sorption-catalytic properties;

7. During water purification, a slight change in its chemical composition is observed and maintenance of the optimal limits of the reaction of the medium is observed-the pH-factor at a level not exceeding 8.5;

8. Shungites are able to compete with AU in the purification of oily waters with the achievement of MPC for drinking water in the amount of 0.***0.1 mg / l; The specific adsorption of petroleum products from the aqueous matrix solution is 2.8 mg / g; The adsorption effect of petroleum products and surfactants reaches *5%.

9. Shungite as a natural ion exchanger attracts ions (salts) of heavy metals, for example iron, onto its surface, and in exchange transfers ions of calcium, sodium, potassium, magnesium into the aqueous solution, etc.
