Resumo

(HC), um processo de oxidação avançada, analisado a partir de diferentes parâmetros de funcionamento como o pH inicial da pressão de águas residuais e da entrada para um tempo de resposta fixo de 90 minutos; parâmetros de projeto foram estabelecidos através da utilização de dois protótipos, variando o número e o diâmetro dos furos no ponto de estrangulamento com o objetivo de determinar as condições ideais para o tratamento deste tipo de contaminante do reator a águas residuais. Obteve um máximo de afastamento de 32,6% da concentração inicial de enxofre sem aplicar qualquer catalisador ou reagente químico; da mesma forma um análise custo-benefício devido a eficiência da tecnologia aplicada em comparação com a energia necessária pelo reator utilizado, mostrando uma diminuição de 198% do custo total do tratamento atual. Finalmente, cavitação hidrodinâmica é uma tecnologia sustentável para o indústria de curtimento de couro.
