Resumen
El objetivo del estudio fue examinar el impacto de diferentes concentraciones de sólidos suspendidos volátiles del licor mezclado en el ensuciamiento de las membranas en un Bioreactor con Membranas Sumergidas (BRMS) en periodos cortos y largos de operación durante el tratamiento del agua residual. Tres BRMS a escala laboratorio fueron operados bajo condiciones críticas, sub-críticas y condiciones de succión intermitente y retrolavados. En cortos tiempos de operación de los BRMS con concentraciones de licor mezclado de 4,200 y 6,150 mg SSVLM L-1, la resistencia hidráulica de las membranas se comportó de manera similar con un promedio de 5.0E+12 m-1 , mientras para una concentración de 7,940 mg SSVLM L-1, su obtuvo una alta resistencia con valores de 1.7E+13 m-1. Los resultados mostraron que con concentraciones altas de biomasa la permeabilidad de las membranas disminuye debido a la formación de una biopelícula en la superficie de las membranas y a la presencia de Sustancia Poliméricas Extracelulares (SPE).
