Preparation of Electrochemically Activated Water in the Presence of Dispersed Fillers

Abstract

Since the quality of surface water has significantly deteriorated, consumers of tap drinking water are forced to additionally purify it by using various filters or low capacity reverse osmosis systems. Water purified by reverse osmosis barely contains mineral salts that are necessary for the human body. The electrochemical method is among the available options for correcting the composition of water, which makes it possible to obtain water with specified characteristics by controlling the conditions of the electrochemical process. Thus, this method allows one to obtain water with a negative redox potential (ROP) that brings antioxidant properties to water. A two-chamber electrochemical apparatus with the electrode compartments separated by a perforated cartridge filled with dispersed materials of different nature, such as cation exchange resin KU-2, activated granular carbon AG-3, and quartz sand, is used to purify tap water. It is shown that the energy consumption is <0.1 kW h/m3 when using a cation-exchange resin. In the time while the initial tap water flow is supplied to the anode chamber, from which it then passes through the cartridge into the cathode chamber and further into the water storage container, the ROP value of water decreases to –100 mV. In this case, water softens and the content of calcium ions decreases from 58 to 2–5 mg/L depending on the electrical current.
