O estudo foi desenvolvido na estação de tratamento de esgoto da Faculdade de Tecnologia Centec-<span style="mso-bidi-font-weight: bold;">– FATEC Cariri</span>,<span style="mso-bidi-font-weight: bold;"> localizada à Rua Amália Xavier de Oliveira, sem nº, Triângulo, município de Juazeiro do Norte – Ceará. </span>E </span><span style="font-size: 11.5pt;">o </span><span style="font-size: 12.0pt; font-family: 'Times New Roman','serif';">monitoramento da estabilidade e desempenho operacional, foi realizado por meio de amostras coletadas quinzenalmente na entrada (afluente) e saída (efluente) do reator, o que possibilitou-se analisar os seguintes parâmetros: pH, temperatura, demanda química de oxigênio (DQO), demanda bioquímica de oxigênio (DBO). De acordo com os resultados obtidos conclui-se que o pH no afluente e efluente apresentou resultados satisfatórios mantendo-se dentro da faixa neutra, no que se refere aos valores de temperatura no afluente e efluente foi considerada ótima para a digestão anaeróbia.</span><span style="font-size: 12.0pt; font-family: 'Times New Roman','serif';">Com relação à eficiência de remoção de matéria orgânica expressa na forma de DQO e DBO, apresentaram valores. Este fato pode ser atribuído à descontinuidade da alimentação do filtro bem como os reagentes químicos que são lançados sem nenhum tratamento, inibindo a metanogênica. E quanto à média do valor de DQO do efluente foi de 205,8 mg/l, ou seja, este efluente não se enquadrou dentro dos limites estabelecido pela portaria n° 154/2002 da SEMACE que cita valores de DQO de 200 mg/l.</span></p><!--[if gte mso 9]><xml> <w:WordDocument> <w:View>Normal</w:View> <w:Zoom>0</w:Zoom> <w:TrackMoves /> <w:TrackFormatting /> <w:HyphenationZone>21</w:HyphenationZone>
