Development and characterization of sulfide-oxidizing biofilms

Development and characterization of sulfide-oxidizing biofilms

Abstract

[CAT] En el present treball s'han desenvolupat i caracteritzat biofilms per a la detoxificació d'efluents contaminats amb compostos reduïts de sofre. En primer lloc es va dissenyar un bioreactor basat en una columna il·luminada que aporta una gran i heterogènia superfície d'adhesió per als microorganismes, i en el qual no hi ha aportació externa d'oxigen. El sistema de control, basat en el potencial redox, permet mantenir constant la concentració residual de sulfur d'hidrogen en el rang micromolar, evitant la inhibició dels microorganismes i mantenint al mateix temps la qualitat de l'efluent generat. [...]

[EN] This works deals with the development and characterization of complex sulfide-oxidizing biofilms. A bioreactor for biofilm development has been designed. The system is based on a non-aerated illuminated packed-column, which provides a large surface for microbial attachment. The reactor operates as a sulfidostat and the control system allows to maintain a constant concentration of residual sulfide in the micromolar range thus avoiding inhibition of sulfide oxidizers due to excessive sulfide load and ensuring a constant quality in the effluent.
