Monitoring granular stability in an industrial UASB reactor treating brewery wastewater

Ver documento

Detalhes bibliográficos
Resumo:An industrial scale UASB reactor treating a brewery wastewater was monitored during several months, in order to assess the usefulness of a morphological parameter relating the filaments length to the projected area of aggregates, LfA, to anticipate washout problems. It was observed that a selective washout of filamentous bacterial forms could explain the decrease of the acetoclastic and hydrogenophilic activity observed in the trial period. This selective washout was predicted by a peak in LfA that occurred just before a steady increase in the effluent VSS values.
