Import substitution in full play

Summary

According to the resolution of the Government of the Russian Federation the economic model of the country development shall be restructured to provide for the import substitution of the technologies applied in strategically significant branches using internal sources. «Nevskii Crystal» Research and Production Company has developed and manufactured a wide assortment of electrolyzers for producing and dosing low concentrated electrolytic sodium hypochlorite. The units conform fully to the international standards.

Equipment manufactured by EKOFES SPE LLC in the field of import phaseout of electrolyzers for the large-scale production of sodium hypochlorite for water disinfection

Summary

Traditionally the sanitary and epidemiologic safety of drinking water is ensured by chlorination that continues to be the most widely used method of water disinfection in the world owing to its sanitary-hygienic reliability, prolonged bactericidal action, relative simplicity and economic efficiency. However, while using liquid chlorine, the problem of its transportation through populated areas and storage of multi-tonnage stocks at the water treatment facilities remains apparent. Low-concentration electrolytic sodium hypochlorite produced at the point of consumption by electrolysis of sodium chloride solution is generally recognized as an alternative disinfectant to liquid chlorine. Those who use foreign technologies and electrolyzers become contingent on foreign service and repair, as well as on the supply of imported components and consumables which causes serious financial difficulties. In addition, foreign companies in the production of sodium hypochlorite use deep-softened Na-cationized water and special salt not lower than Extra brand. The successful promotion of high-efficiency domestic electrolyzers in the field of import phaseout became possible only with taking into account the demands of water utilities for the use of the cheapest and available raw materials (table salt not higher than A-number), as well as for the after-sale service by the supplier and the manufacturer warranty to eliminate unforeseen shutdowns of the equipment, emergency failures or consequences of force majeure in the shortest possible time. The established in Russia (EKOFES SPE LLC) production of high-capacity electrolyzers that are not inferior in their technical and economic performance to foreign counterparts will provide for complete abandoning foreign supplies and implementing import phaseout of this type of equipment by a domestic manufacturer.

GRUNDFOS solutions for disinfection of water and effluents

Summary

The SARS-CoV-2 pandemic has revealed many problems in the epidemiological safety systems of almost all countries of the world. GRUNDFOS has developed a wide product line that can be used as part of integrated solutions for establishing local water treatment systems, as well as for disinfecting closed public water supply systems. Among them are Smart Digital metering pumps, that ensure the high metering accuracy and the ability to finely control the concentration of dosed chemicals, as well as the solutions for the disinfection of public water supply systems – GRUNDFOS Selcoperm electrolysis units and GRUNDFOS Vaccuperm industrial chlorination units. Selcoperm units provide for producing sodium hypochlorite directly at the point of use. Vaccuperm is a vacuum dosing system that disinfects water with gaseous chlorine.
