Resumen

Se investigó la eficiencia de desinfección de agua de pozo y degradación de materia orgánica de agua residual de tratamientos por desinfección solar (SODIS-CPC) y fotocatálisis (TiO₂ en suspensión [TiO₂susp. - CPC], catalizador de concreto mezclado con TiO₂ [CI-CPC] y catalizador de concreto impregnado con TiO₂ [CII-CPC]) acoplado a un colector parabólico compuesto 1.15 X (CPC 1.15X) y fotorreactor de botella PET de 1.5 L. Las evaluaciones se llevaron a cabo en el mes de septiembre y octubre entre las 8:00 y 16 horas, con radiación solar menor a los 1000 W/m². Los resultados demostraron que el CII-CPC logró tener una eficiencia máxima de 99.99 % de inactivación de coliformes totales, fecales y E. coli en el agua de pozo. El SODIS-CPC tuvo una eficiencia máxima de remoción DBO y DQO de 93.08 y 94.94 %, respectivamente. La eficiencia de desinfección y degradación depende de la intensidad de la radiación incidente, el tiempo de exposición, concentración de TiO₂ y la geometría del reactor.
