    • Bioprocesses for the removal of nitrogen oxides from polluted air 

      Jin, Yaomin; Veiga, María Carmen; Kennes, Christian (Wiley-Blackwell, 2005)
      Nitrogen oxides (NOx) of environmental concern are nitrogen monoxide (NO) and nitrogen dioxide (NO2). They are hazardous air pollutants that lead to the formation of acid rain and tropospheric ozone. Both pollutants are ...

    • 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 ...

    • Partial Nitrification of Wastewater from an Aminoplastic Resin Producing Factory 

      Fernández, A.; Vilar, A.; Ben García, Marta; Kennes, Christian; Veiga, María Carmen (IWA Publishing, 2005)
      Nitrification via nitrite was studied in two aerobic reactors treating wastewater from an aminoplastic resin producing factory at HRT varying between 1.37-1.89 and 2.45-3.63 days. Both reactors were fed with concentrations ...

    • 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 ...
