Abstract

Los  bioreactors  de  membranas  (BRMs)  representan  una  tecnología  emergente  por el  tratamiento  de  aguas  residuales  alrededor  del  mundo.  En  esta  línea,  siete  BRMs municipales  recientemente  construidas,  con  capacidades  entre  1,100  m3·día-1  to  35,000 m3·día-1(hasta 100,000 m3·día-1 en total) han sido diagnosticadas. La evaluación del diseño y operación a través de encuestas ha sido clasificada y descrita en tres categorías distintas: i) limitaciones de diseño, ii) fallos en el equipamiento y en las membranas y iii) problemas operacionales, con sus pertinentes interrelaciones entre ellos. Los dos BRMs más antiguos presentaron membranas rotas seis y siete años de operaciones, respectivamente, siendo necesario su reemplazamiento. Mientras que las espumas (foaming) han sido identificadas como mayor problema de operación en común, otros problemas como el taponamiento (clogging), la reducción del proceso de desnitrificación o el aire en las líneas de permeado han sido los que más preocupan a sus explotadores. Además, el ensuciamiento no ha sido mencionado en ninguna de las encuestas y el consumo energético identificado como la mayor limitación de dicha tecnología.
