Treatment of fish processing wastewater with microalgae-containing microbiota
 
Informations principales
Titre: Treatment of fish processing wastewater with microalgae-containing microbiota
Type de l'élément: Publication
Résumé: Two photobiorreactors inoculated with microalgae from a lagoon containing aerobically treated swine slurry and sludge from a membrane submerged bioreactor treating winery wastewater were established to treat fish processing wastewater (FPW) at 23 and 31 °C, respectively. Decreasing HRT was applied to the photobiorreactors from 10 to 5 days. Ammonium was completely exhausted in both photobiorreactors; however, volatilization was detected as the main removal mechanism for the highest applied load whereas biomass assimilation was the main mechanism for the lowest applied load. Approximately 70% of TCOD (total chemical oxygen demand) and phosphate removal was achieved regardless of temperature. Biomass productivity was as much as 55% higher at 31 °C than at 23 °C. These results suggested that fish processing wastewater could be effectively treated using this technology under the two experimental conditions.
