Uso do filtro de areia na adequação do efluente da ETE mangabeira para ultrafiltração

Abstract

The scarcity of water resources, together with the large volume of sewage produced by the population come from arousing the search for efficient and low-cost methods for domestic wastewater treatment, in relation to conventional, despite satisfactory are not enough so that the final product is applied in reuse. In this sense come surging ultrafiltration in Brazil, which already has proven efficiency abroad, reducing potentially contaminants parameters, being fairly applied to the treatment of industrial waste. However, these membranes possess great sensitivity to the presence of organic matter, and need that sewer is suitable for your treatment, thus preventing the clogging of pores and affecting your efficiency. In view of this need, this study assessed the implementation of a sand filter as pre-treatment for ultrafiltration. To analyze the behavior of this system were made analyses of temperature, pH, BOD5, COD and ammonia nitrogen. The results showed no significant change in the quality of the sewage that fueled the membranes, indicating the need to seek out new fitness techniques.
