• The chapter characterizes the Fenton process. The conditions in which it must be conducted are presented. The reagents used are specified. The influence of reagent doses on the efficiency of the process is discussed. The most important chemical reactions taking place and the most important factors limiting the possibility of using the process are presented. The advantages and disadvantages of the process and its modifications including the additional use of other homo and heterogeneous catalysts, light, and electric current, aimed at increasing efficiency and reducing the impact of factors reducing the efficiency of the process, are presented. The Fenton process is one of the advanced oxigen processes (AOPs), discovered in 1894. In the Fenton process, as in any AOP, radicals are formed. The Fenton process consists of two independent stages: the Fenton reaction and coagulation. The first step of the Fenton process, the Fenton reaction, involves oxidizing Fe to Fe while reducing hydrogen H2O under acidic conditions to form hydroxyl radicals that could break down almost all known organic pollutants. However, the decomposition of organic compounds is still possible because Fe compounds are considered strong oxidants. The process can continue because the hydroxyl radical can react with compounds adsorbed on flocs. The dose of coagulant needed is very important, due to the possible content of colloids and suspensions in the treated wastewater. Due to the proven and recognized effectiveness of the Fenton process, it is a promising method of wastewater treatment.
