Electrochemical activation of water, water solutions: the past, present and
future. History of the development and organization of work in the field of
electrochemical activation. Home work was initiated in 1972 studies at the Tashkent
Scientific Research Institute of Natural Gas of the Ministry of Gas Industry of the
USSR (SredAzNIIGas) in the field of electrochemical activation. After the first
successful test of electrochemical methods to control drilling fluid properties and
water [2, 3, 4, 5, 6, 13], laboratory and industrial settings for the anodic or cathodic
(unipolar) treatment of water were created in process of drilling oil and gas wells, and
aqueous solutions. During the period from 1973 to 1981 a team of researchers from
SredAzNIIGas more than 200 copyright certificates were obtained for inventions in
the field of electrochemical activation (the term "electrochemical activation" in 1975
in determining whether changes in the parameters of relaxation of dilute solutions as
a result of the previous unipolar electrochemical treatment). Thanks to the
publications in the scientific-popular magazines, newspapers, scientific journals
between 1981 and 1985. results of research and practical use of industrial plants for
the electrochemical activation of water and aqueous solutions have become known to
the general scientific-technical community and attracted the attention of these works
of many researchers from various fields. Thus, it formed an informal community of
experts and scientists working in close scientific-technical cooperation with the
authors of ECA technology [5, 6, 13]. This community exists and continues to
develop and is now [2, 3, 4].
Studies carried out by specialists and scholars of various branches of the period
from 1979 to 1989, demonstrated the tremendous opportunities ECA as a universal
instrument for the transformation of many traditional technologies and turn them into
clean, waste-free, highly efficient processes. Even from a far from complete list of
inventions that period visible breadth of range of application of ECA and
considerable effort (number of experts), centered on research and practical
application of this technology. However, the practical use of the results hampered by
the lack of industrial technical electrochemical systems capable at low specific power
consumption provides an electrochemically activated solutions from fresh or brackish
water.
In addition, there was no experience of adapting new technologies based on the
ECA to the conditions of industrial use. In the 80-ies was formulated the concept of
