Abstract:

The biological nitrogen removal from wastewater is usually performed by nitrification and denitrification processes. The objective of the present work was to use experimental planning and response surface to assess the influence of the variables cycle time (CT) (12, 16, and 20 h) and ammoniacal nitrogen (NH4-N) concentration (80, 100, and 120 mg.L1) on the efficiency of nitrogen removal from a poultry slaughterhouse wastewater using a sequencing batch reactor (SBR). Results have shown that the CT and the NH4-Nconcentration have a significant influence on the variables analyzed. The most representative results were obtained with CT between 16 and 20 h, and NH4-Nconcentrations in the range of 80 to 100 mg.L1. At these ranges, the mean efficiency of NH4-N oxidation and NO2-N and NO3-N removal were 90%, 94%, and 97%, respectively.
