O uso da cavitação hidrodinâmica aplicado ao tratamento de água

Abstract

The hydrodynamic cavitation is presented as an advanced oxidation process (AOP), allowing to integrate the processes of water treatment for human consumption. This research aimed to investigate the effects of different hydrodynamic cavitation reactors for treating water contaminated with sewage, evaluating the microbiological contamination and physicochemical parameters. Three models were constructed with different rotors reactors (R1, R2 and R3). The results obtained in the reactors R1, R2 and R3 have shown a reduction in the concentrations of chemical parameters in all samples, particularly nitrites, nitrates, bicarbonates, and total hardness, while the microbiological contamination was completely inactivation (total coliforms and Escherichia coli).
