    • Formaldehyde biodegradation and its inhibitory effect on nitrification 

      Eiroa, Marta; Kennes, Christian; Veiga, María Carmen (Wiley-Blackwell, 2004-05)
      The simultaneous removal of formaldehyde and ammonium in aerobic cultures and the inhibitory effect of formaldehyde on ammonium oxidation were investigated. The influence of a co-substrate, methanol, on formaldehyde ...

    • Phenol biodegradation and its effect on the nitrification process 

      Amor, L.; Eiroa, M.; Kennes, Christian; Veiga, María Carmen (Elsevier, 2005-08)
      Phenol biodegradation under aerobic conditions and its effect on the nitrification process were studied, first in batch assays and then in an activated sludge reactor. In batch assays, phenol was completely biodegraded at ...

    • Simultaneous nitrification and formaldehyde biodegradation in an activated sludge unit 

      Eiroa, M.; Kennes, Christian; Veiga, María Carmen (Elsevier Sciencie lted, 2005-11)
      The simultaneous removal of formaldehyde and ammonium in a lab-scale activated sludge unit was investigated. The unit was operated at a hydraulic retention time of 2.4 days with an ammonium concentration in the influent ...

    • Treatment of slaughterhouse wastewater in a UASB reactor and an anaerobic filter 

      Ruiz,Isabel; Veiga, María Carmen; Santiago, P. de; Blázquez, R. (Elsevier, 1997-06)
      A study was performed to assess the feasibility of anaerobic treatment of slaughterhouse wastewaters in a UASB (Upflow Anaerobic Sludge Blanket) reactor and in an AF (Anaerobic Filter). Among the different streams generated, ...
