A chapter in Ozonation - New Aspects from IntechOpen

Abstract: Ozone, a triatomic oxygen molecule, is a powerful oxidant generated by water electrolysis or produced in situ using the corona discharge method. Typical applications in water treatment involve the disinfection, disposal of virus, bacteria, and hydrogen sulfide removal and are responsible for odorous compounds in septage tanks and oxidation lagoons. Recently, electrocoagulation and cavitation have evolved to increase the efficiency of ozone gas disinfection. Electrocoagulation (EC) permits the sanitation of wastewater, the destruction of oil-water emulsions, and heavy metals present in mining waste and manufacturing industry. EC is useful when traditional disinfection methods using chemical agents or biological treatment is not completely efficient. Using the EC technology proposed by Reingeniería en Saneamiento Ltd., replacement of sacrifice electrodes is not estimated. Cavitation and ozone systems, as beneficial processes in water treatment technology are supported by electroflotation, electrocoagulation, and electrochemistry in urban wastewater plants to accomplish effective solutions in different processes. Along with the chapter, how modular plants can be designed to achieve the correct purification system based on a previous diagnosis of the process is explained. Finally, due to complexity of treatment process, automation need to advance from manual control to programmable logic controllers if control architectures for water treatment system advance in the same way the depuration process is properly controlled.
