SUMMARY:

Water is the central axis for the sustainable development of countries, which must be consumed and disposed of conscientiously, but it is a limited resource, increasingly scarce in some regions of the world. Contamination of surface and underground water sources by organic chemical compounds is definitely a matter of concern. Lately, many technological alternatives for the treatment of wastewater and drinking water for human consumption have been proposed, among them the advanced oxidative processes (AOPs) have gained acceptance for the disinfection and decontamination of effluents. Treatments by advanced oxidative processes (AOPs) have shown good effectiveness in eliminating chemical and microbial contaminants in water. The main highlight of the (AOPs) is the in situ production of the highly reactive species, the hydroxyl radical (•OH), the superoxide radical (•O2-) and the sulfate radical (•SO4-) which can fragment organic pollutants and pathogens . These processes are based on electrogeneration of hydroxylic radicals (•OH), which can react non-selectively with organic pollutants until their complete removal. Radicals (•OH) have a high redox potential (2.8 eV/SHE) and are not selective, being able to attack organic compounds by four ways: hydrogen abstraction, combination or addition of radicals and electron transfer. In this work, a pilot plant and a reactor were built for the electrochemical treatment of anodic oxidation in wastewater from the petroleum industry, textile industries, pharmaceuticals and pesticides, disinfection of water with potability potential as a substitute for chlorine that can be a remediation alternative with low cost of assembly, installation and energy consumption, solar energy sources can be used. The results of this research clearly reveal that electrochemical oxidation - anodic oxidation used on a pilot plant scale is efficient and can be used in conjunction with other wastewater treatment techniques, as well as an alternative for disinfection of water with potability potential, without the use and storage of chlorine. The reactor proved to be efficient, and anodic electrodes of different materials can be applied according to the economic viability of the material. Like the reactor, the pilot plant can be used for other types of effluents, enabling further research and consequently increasing the variety of effluents that can be treated by the same equipment.
