The history of the flow-through electrochemical modular elements began in 1989 with the creation of first industrial element model known as FEM-1 element by Bakhir V.M. and Zadorozhny Yu.G. (UK patent GB 2 253 860). Read more about history of creation of FEM elements.
At the same time Bakhir V.M. and Zadorozhny Yu.G. organized an industrial enterprise under the name “Laboratory of Electrotechnology”, the main task of which was the production of flow-through electrochemical modular elements.
Altogether there were produced about 1000 FEM-1 elements. They were tested in a variety of electrochemical devices and showed a high technical and economic efficiency.
In 1992, the same authors developed the industrial sample of flow-through electrochemical modular element known as FEM-2. Significant technical features of this element are protected by RF patent № 2042639. Two companies (“Laboratory of Electrotechnology” and JV “Emerald”) produced about 60 thousand FEM-2 elements for the period from 1992 to 1997.
In 1994 Bakhir V.M. and Zadorozhny Yu.G. developed an industrial sample of flow-through electrochemical modular element named as FEM-3 element. Technical solutions implemented of this element are protected by the RF patent № 2078738. The company “Laboratory of Electrotechnology” produced about 700,000 FEM-3 elements for the period from 1994 to 2008. Further development and improvement of the design of flow-through electrochemical modular elements and technology of their practical use in various electrochemical devices contributed to the development of new types of elements known as FEM-4 (1998 year of development, patent RF № 2145940), FEM-7 (2000 year of development, patent RF № 2176989), FEM-9 (2004 year of development, patent RF № 2270885). All technical solutions protected by these patents contain numerous secrets which are not mentioned in patents descriptions, that is why attempts of unscrupulous people and companies to copy these products always led to the low quality and short life of such products.
At the end of 2008 the company "Laboratory of Electrotechnology" ceased production of both flow-through electrochemical modular elements FEM-3, FEM-4, FEM-7, FEM-9 and flow-through electrochemical reactors RPE with these elements, due to the fact that a group of authors under the guidance and direct participation of V.M. Bakhir, and Yu.G. Zadorozhny created MB-11 and MB-26 elements with significant technical, technological and functional advantages in comparison with FEM elements. New elements began to be produced since the beginning of 2009 by the company “Laboratory of Electrotechnology”. They are protected by a common patent, which covers for the first time at the micro level all the basic distinguishing features of electrolytic cells, which allows to implement the principle of construction of technical electrochemical systems of any complexity and productivity in accordance with the laws of the formation of living organisms from single cells.
All these products were mass-produced by LLC "LET" on the basis of a contract between the patentee and the enterprise.
At the beginning of 2011 scientists and specialists of Vitold Bakhir Electrochemical Systems and Technologies Institute completed research that served as a basis for the development of a number of fundamentally new designs of MB elements and, correspondingly, new technical electrochemical systems, the right of mass production of which passed in middle of 2011 by the patentee to LLC "Delfin Aqua". Concurrently, the company LLC "LET" was deprived of the right to manufacture products according to all mentioned above as well as any other patents of V.M. Bakhir and his colleagues.
Is MB element of new generation all the last author's achievements including "know-how" are concentrated. Electrochemical MB reactors are manufactured from advanced materials. Each modular electrochemical reactor (element) produced by Delfin Aqua has a seal with the emblem of the manufacturer (Delfin Aqua), as well as the guarantee of the author's involvement and control – the emblem of Vitold Bakhir Electrochemical Systems and Technologies Institute – the company leading in the development of new design and technological solutions in the field of electrochemical activation.
