Abstract:
The advantages of electrochemical wastewater treatment methods, especially those involving reagent generation, are multifaceted. First, such systems are highly automated and allow for precise control of process parameters through regulation of current and voltage. Second, they ensure compactness of treatment facilities, which is especially important for industrial enterprises with limited space. Third, electrochemical technologies allow achieving a high degree of purification of a wide range of pollutants, including biodegradable organic compounds, heavy metals, and pathogenic microorganisms. The environmental safety of ferrate technology should be particularly noted-unlike chlorination, the use of ferrates does not produce toxic halogenated organic compounds, and the end products of the reaction (iron oxides) are non-toxic and can be easily removed from the treated water. The areas of practical application of electrochemical treatment with ferrate generation are extremely diverse. In the industrial sector, such systems are effective for treating wastewater from chemical, pharmaceutical, and textile enterprises containing persistent organic pollutants. In municipal services, ferrate technologies can be used for post-treatment of wastewater after biological treatment, ensuring the removal of residual organic substances and complete disinfection. Despite the obvious advantages, the widespread introduction of electrochemical treatment methods with ferrate generation faces a number of technological problems. The main problems are related to the instability of ferrates in neutral and acidic environments, which requires their immediate use after generation. Another significant limitation is the relatively high energy consumption of the process, especially under suboptimal electrolysis conditions. These problems could be solved by developing a laboratory electrochemical module that would combine the processes of ferrate generation and use in a single technological cycle for wastewater treatment.
