Historical note

Platinum is one of the rarest metals. The word PLATINA literally means "little silver". Today platinum is not only a precious metal, but - more importantly - one of the important materials of the technical revolution. Today, about half of all platinum consumed is used as catalysts for various reactions in almost all industries.

Platinum is one of the main catalysts in the modern chemical industry. Platinum, especially in a finely divided state, is a very active catalyst for many chemical reactions, including those used on an industrial scale. For example, it catalyzes the reaction of hydrogen addition to aromatic compounds even at room temperature and atmospheric pressure of hydrogen.

Platinum catalysts accelerate many other practically important reactions: hydrogenation of fats, cyclic and aromatic hydrocarbons, olefins, aldehydes, acetylene, as well as redox reactions.

About technology

"Platinum filtration" is a method of processing vodka, which purpose is to improve the organoleptic properties of the drink. Its essence is as follows: vodka, processed on a coal column, using the "Silver filtration" method or in another regulated way, is passed through a filtration system of the USF series (TU 5131-009-10471723-2004), consisting of a pumping unit, a filter holder, a rotameter and a shut-off fittings, with EPSF.UPt filter cartridges based on carbon impregnated with platinum, manufactured by NPP Technofilter, and sent to the tank with filtered vodka.


Additional treatment of vodkas in order to improve organoleptic properties.

Features and advantages 

Features Advantages for customers

Stable quality

  • High rating of organoleptic properties of the product 
    •  smooths out unpleasant tastes and odours of alcohol shades in the flavour
    •  imparts softness, balance and nobility to the taste and flavour
  • high efficiency of vodka processing using EPSF.UPt filter cartridges loaded with platinum-impregnated cocoa carbon
  • High processing rate of vodka resulting from extremely high catalytic properties of platinum
  • Increased throughput of filter cartridges
  • Retention and improvement of organoleptic prope rties during prolonged storage

Prompt and easy maintenance

  • Prompt and easy replacement of filter cartridges

Large throughput of EPSF.UPt filter elements (minicolumns) at minimum expenses

  • Average throughput of a 250 mm high EPSF.UPt filter cartridges is up to 10,000 dal 
  • Minimum expenses on test filtration resulting from high hardness of coconut shell carbon and lack of attrition

The technology is based on EPSF.UPt filter cartridges loaded with platinum-impregneted coconut shell activated carbon. The technology has been patented by NPP Technofilter

The EPSF.UPt filter cartridge is a carbon “minicolumn”: carbon is loaded between outer and inner shells, liquid is delivered through the lower opening of the outer shell, passes through carbon and comes out inside the cartridge through the upper opening of the inner shell.

This design takes into account the ability of carbons to swell in the course of operation and precludes the possibility of “channelling” even at high filtration rates.

Carbons loaded into the minicolumn feature high hardness and large surface area. The method of impregnation used in production of the filter cartridge precludes migration of platinum into the filtrate. By connecting cartridges with a height of 250 mm by heat sealing, elements with a height of 500, 750 and 1000 mm are produced.

Recommended modes of operation

Recommended optimum rate of vodka processing is about 25 to 40 dal/hour for one 250 mm high EPSF.UPt cartridge. Throughput of one 250 mm high EPSF.UPt cartridge is about 7,5000 to 10,000 dal.

EPSF.UPt filter cartridges

EPSF.UPt filter cartridges are supplied as part of USF systems. Depending on the required vodka processing rate, the number and height of filter cartridges and the grade of the USF filtration system are selected.

USF filtration systems (“Silver filtration”) are used in the alcoholic beverage industry and are intended for treatment of water-alcohol mixtures and vodkas. The minimum production rate of the systems is 150 dal/hour, the maximum production rate is up to 3,000 dal/hour.

The systems are compact, are mounted on a single frame and consist of:

  • pumping unit (German-made GRUNDFOS pump or Russian-made ONTs pump, explosion-proof construction) 
  • carbon filtration unit (filter holder made of 12Kh18N10T stainless steel having an inspection window, complete with a pressure gauge, designed for various numbers and heights of ESF.UPt filter cartridges)
  • piping manifold, stop valves;
  •  flowmeter

The system can be supplied complete with a control console having an automatic switch and a frequency converter as well a prefiltration unit for protection of carbon elements from mechanical impurities (scale, sand and carbon dust, etc).

The systems are designed and produced in accordance with requirements of the Customer.

Silver Filtration systems have been certified (Certificate No ROSS RU.AYa56.V20239) along with EPSF.UPt filter elements (Supplement to the certificate of conformance No ROSS RU.AYa56.V20239).

Plants with platinum-containing carbon filter cartridges operate at JSC "Bashspirt", "Khabarovsk" distillery, "Experimental plant " Niva " LLC, " Khortitsa " distillery Ukraine, " Brest distillery "Belalko" Republic of Belarus, "New City Holdings" Croatia, "STUMBRAS" , "Vilniaus Degtine", Lithuania.
