Avaliação do efeito da paralisação da aeração no tratamento biológico aeróbio da água residuária da indústria de farinha de mandioca
The cassava wastewater, generated during the cassava processing, is a pollutant and toxic waste. This study compared the efficiency of the cassava wastewater treatment in three batch aerobic systems with a ru1nning time of 24 hours, and aeration stoppage of 12h with 2,500, 6,000 and 10,000 mg COD L-...

| Sumario: | The cassava wastewater, generated during the cassava processing, is a pollutant and toxic waste. This study compared the efficiency of the cassava wastewater treatment in three batch aerobic systems with a ru1nning time of 24 hours, and aeration stoppage of 12h with 2,500, 6,000 and 10,000 mg COD L-1 . The systems were evaluated for COD, pH, SVI and F/M. The results showed that the reactor with aeration stoppage for 12 hours, with 2,500 mg COD L-1 , presented the best reduction in a process with considerable energy consumption saving compared to traditional continuous systems. |
