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.

在分散填料存在下制备电化学活化水

摘要

由于地表水的质量已显着恶化，自来水的消费者被迫使用各种过滤器或低容量反渗透系统对其进行额外净化。通过反渗透净化的水几乎不含人体必需的矿物盐。电化学方法是校正水成分的可用选项之一，它可以通过控制电化学过程的条件来获得具有特定特性的水。因此，这种方法可以让人们获得具有负氧化还原电位 (ROP) 的水，从而为水带来抗氧化特性。一种两室电化学装置，其电极室由填充有不同性质的分散材料的穿孔盒隔开，如阳离子交换树脂KU-2、活性颗粒炭AG-3、石英砂等，用于净化自来水。结果表明，能耗<0.1 kW h/m³使用阳离子交换树脂时。在初始自来水流被供应到阳极室，然后从阳极室通过滤筒进入阴极室并进一步进入储水容器的时间内，水的 ROP 值降低到 –100 mV。在这种情况下，水会软化，钙离子的含量会根据电流从 58 降至 2–5 mg/L。
