Treatment of effluents from an ice cream producing plant using sequential batch reactors

The objective of this research was to evaluate the efficiency of a sequential batch reactor operating in the treatment of effluents from an ice cream producer. They implemented two times of 10 and 12 hours, an anaerobic, aerobic and anoxic operational sequence, and a cell retention time of 25 days. The physicochemical parameters measured were chemical total oxygen demand, ammoniacal nitrogen, nitrites, nitrates, orthophosphates, total phosphorus, pH and total alkalinity at the beginning, end of each phase and outlet of the reactor for each treatment evaluated. According to the results obtained, the percentages of COD removal were between 89.8 and 94.6% for 10 and 12 h, respectively, without statistically significant differences between the applied times. The SBR was efficient for the removal of the nutrients present in the industrial effluent, reaching a maximum removal of total nitrogen of 81.0% and total phosphorus of 51.0%.
