El vertimiento de aguas residuales domesticas e industriales es uno de los mayores problemas que afrontan los ríos, el alto nivel de contaminación afecta directamente a la vida acuática y vegetal. Los productores que viven en las cercanías del rio Chillón utilizan estas aguas para regar sus chacras de cultivos, muchos de los productos alimenticios son llevados a centros comerciales de la ciudad para luego ser consumidos por la población. Debido a ello, por esta investigación se pretende disminuir o eliminar los contaminantes mediante la medición de la Demanda Bioquímica de Oxigeno (DBO); ya que es considerado como una prueba de gran valor en el análisis de los efluentes de aguas negras o muy contaminadas. Los resultados obtenidos muestran que la muestra inicial promedio fue de 173 mg/L. luego del tratamiento a 15 minutos con Micro Nanoburbujas de aire se obtuvo 53 mg/L y con Micro Nanoburbujas de ozono se obtuvo 53 mg/L. la mejor eficiencia obtenida fue 69.36%.
