    • A Comparative Study of Physical and Chemical Processes for Removal of Biomass in Biofilters 

      Flores-Valle, Sergio Odín; Ríos-Bernÿ, Omar; Chanona-Pérez, Jorge; Fregoso-Aguilar, Tomas; Morales-González, Ángel; Prado Rubianes, Óscar Jesús; Herrera-Bucio, Rafael; López-Albarán, Pablo; Morales-González, Ángel; Garibay-Febles, Vicente; Godínez Domínguez, Enrique; Kennes, Christian; Veiga, María Carmen; Mendoza-Pérez, Jorge Alberto (MDPI, 2011-08)
      After 6 months of operation a long-term biofilter was stopped for two weeks and then it was started up again for a second experimental period of almost 1.3 years, with high toluene loads and submitted to several physical ...

    • Biofiltration of waste gases in a reactor with a split-feed 

      Mendoza, J.A.; Veiga, María Carmen; Kennes, Christian (Wiley-Blackwell, 2003-06)
      The efficiency of using different feed strategies was evaluated in the case of a gas-phase biofilter packed with an inert carrier material. During a preliminary control-period, the biofilter was first fed with a single ...

    • 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 ...

    • Autotrophic deodorization of hydrogen sulfide in a biotrickling filter 

      Jin, Yaomin; Veiga, María Carmen; Kennes, Christian (Wiley-Blackwell, 2005-09)
      The removal of hydrogen sulfide (H2S) from airstreams was studied in a biotrickling filter (BTF) packed with plastic Pall rings operating with counter-current flows of the air and liquid streams. Experiments were performed ...

    • 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 ...
