GENERAL AND HISTORIC INFORMATION ABOUT CONSORTIUM AND FEATURES OF THE PRODUCT

    The joint task of companies associated in the consortium "ElectroEcoTechnologies" is a development and practical realization of technologies for water treatment with use the electrochemical methods, as well as designing, manufacturing and sale of appropriate equipment. The business activity geography of companies interacting within the framework of the EET consortium spreads over Russia (with the centre  in Saint Petersburg). The basic type of a product of the EET consortium – water electro-conditioners ELECON and CASCADE® in different modifications for decision of varied practical problems by way of syntheses of applicable apparatus-technological schemes.

    Certain activity carried out within the framework of the "Association of Manufacturer of Medical Products Nord-West" in connection with membership in this organization.

    Today unique devices ELECON and CASCADE ® of new generation is offered to attention of wide circles of the consumers of equipment for cleaning water. This is new technology, intended for optimum decision an age-long of economic problem – cleaning of potable water, is based on theoretical and experimental researches which have been carried out under a management of V. Andreyev, as well as the invention, made by him on the base of received scientific results. Water electro-conditioners are presented by models, having different performance, output and purpose. New equipment is patented.

    A clear choice that brings numerous advantages to the purification/filtration process is the use of input electrical energy, in the form of a polarizing electric field, to aid in the cleansing ability of simple filter materials. Past attempts to use electric fields in water purification devices met with various practical problems associated with electrode design and material choice. Other early efforts at using electric fields to aid in filtration were also handicapped by lack of basic understanding of the very complex, dynamic electrochemical environment formed by the treatment water, electrode elements and filter bed material. Traditional filtration methods, which widely use simple adsorption as the basic physical mechanism of operation, or even membrane or chemical-reagent methods, do not simultaneously filter organic, particulate, and chemical pollutants. Practically any system built to accomplish complex water purification goals consists of elements that require frequent replacement. Often these components are the most important filtration working elements (for example, membranes, adsorbents, cassettes, etc.) One of our basic design goals for electroconditioners was to eliminate the need for frequent and expensive replacement filter components. This goal has been achieved in ELECON and CASCADE water purification systems without loss of purity standards or reduction of device operation lifetime under high load conditions. This water purification breakthrough was brought about by both basic physical and engineering science advances.

    An extensive program of theoretical and experimental research was under taken in Russia during the past decade to resolve many of the fundamental issues concerning the complex electro-chemical and hydrodynamic behavior of such electro-active filtration systems. The basic problem of electrode corrosion and subsequent interaction with the filtration bed material were successfully addressed and solved. These theoretical and experimental advances have lead naturally to the design and implementation of electrosorption based water purification technology in the series of electric purification products. The extremely wide application opportunities of ELECON and CASCADE water systems have been opened due to this extensive knowledge base and should provide an atmosphere for further innovation in purification technology. These developments have shown the large benefit in filtration capability when electrical field energy is used in water systems to aid physio-chemical and electro-chemical processes. As an added utility all of these processes are carried out simultaneously in the working chamber of a single CASCADE device, eliminating for example, the need for multiple systems to deal with organic or metallic contaminants. As a result, the CASCADE consumer receives water of the highest possible quality conditioned in a economically attractive once through system In particular, the CASCADE water systems provide complete purification from many kinds of micro-particles of organic and inorganic origin, such as: protozoa, bacteria, viruses, helminthes, ova, particles of humus and minerals, iron, and water-insoluble petroleum products. CASCADE systems also soften water and are able to clarify toxic mineral and organic components such as heavy metal ions, manganese, phosphates, nitrates, nitrites, sulfides, cyanides, mercaptans, phenols, etc. while retaining the potassium and sodium ions in water necessary for proper human health.

    Water electroconditioners are especially effective in the removal of iron in municipal water supplies. The removal of iron is chemically complex and complicated by the fact that the iron present in water takes various forms (bivalent and trivalent ions, macro-particles and micro-particles of a rust, or so-called colloidal iron). The so-called “iron problem" in Russia and other countries of the CIS is caused by the extension of chalybeate water-bearing horizons, and the long-term practice of using pipes made of so-called “black” metals in construction. The current widespread use of expensive water heating, and sanitary equipment which are effected by colloidal iron pollutants points to the especially urgent need for their removal. The CASCADE product line of water purification devices is designed to easily filter these increased concentrations of iron and chlorine present in many water systems.
