Efeito da adição de cloreto férrico ao esgoto afluente a um reator UASB
The discharge of effluents containing nitrogen and phosphorus compounds, even when previously treated, has been a source of problems to the water bodies from which this water is used for public supply. These compounds are nutritional for algae, causing blooms that produce toxins and result in higher treatment costs (application of activated carbon, pre‐chlorination). Therefore, their removal has become as important as the reduction of the carbonaceous organic load. The upflow anaerobic sludge blanket reactors – UASB are a very compact type of treatment, with simple operation and monitoring procedures and, consequently, they present very competitive implementation and operation costs in comparison to other known processes. This study intends to assess the UABS capacity to remove phosphorous and organic matter with the injection of coagulants (ferric chloride, in this case) at the raw sewage inlet and through the sludge blanket. The purpose is to analyze COD and phosphorous removal in an actual UASB system that cannot be enlarged, located in an area of water sources. It is a simple and compact process with a relatively low sludge production, if compared to other aerobic processes. If an increase of the UABS treatment capacity with the simple addition of coagulants is found, this alternative may be an option to several systems that operate under similar conditions.

Resúmen disponible en inglés y portugués. O lançamento de efluentes, ainda que tratados, contendo compostos com nitrogênio e fósforo tem causado problemas para os mananciais de onde se retira água para abastecimento público. Com a característica de servirem como nutrientes para as algas, cuja floração produz conseqüências como geração de toxinas, aumento de gastos com tratamento (com aplicação de carvão ativado, pré cloração, etc.), entre outros, sua remoção passou a ser tão importante quanto a redução da carga orgânica carbonácea. Por um outro lado, os reatores anaeróbios de fluxo ascendente (conhecidos como UASB’s – upflow anaerobic sludge blanket – ou RAFA’s), representam uma forma de tratamento bastante compacta, de simples operação e monitoramento e, como conseqüência, com custos de implantação e operação bastante competitivos diante de outros processos que hoje temos conhecimento. O estudo proposto visa avaliar a capacidade de remoção de fósforo e de matéria orgânica na operação dos reatores tipo UASB com a injeção de coagulantes (neste caso, cloreto férrico) na entrada do esgoto bruto na unidade, atravessando juntamente com o mesmo através do manto de lodo. O objetivo do estudo é a análise da capacidade de remoção de DQO e fósforo de um sistema de reatores UASB real localizado em área de mananciais e sem possibilidades para ser ampliado. Por se tratar de um processo simples e compacto e com produção de lodo relativamente baixa se comparada a outros processos aeróbios, caso se verifique o aumento na capacidade de tratamento nos UASB’s com a simples adição de coagulantes, essa alternativa poderá se apresentar como opção para diversos sistemas com condições semelhantes.
