Abstract

The removal of organic matter and nitrogen in wastewater
from an animal food processing company was studied using
a pilot Sequencing Batch Reactor (SBR). Trials were carried out with 2 types of waste water; washing water which is characterized by a high content of organic matter and condensed water which has a high concentration of ammoniacal nitrogen. The time of operation of the reactor was 252 days using eight different stages depending on the organic loading rate (OLR) and ammoniacal loading rate (ALR). The highest removal efficiencies were obtained for an OLR of 3.24 g CODF/L.d and an ALR of 1.102 g NH4 +- N/L.d, with a ratio of 9:1 of washing water:condensed water and with the BOD5/ NH4
+-N relationship in a range of 2.0 - 4.0.
