Tratamento de efluentes: uma investigação de filtros anaeróbios através da proposta do professor Cynamon.

Abstract

It is essential in a society increasingly concerned with environmental issues using techniques and procedures that will treat the effluent generated in their activities to ensure environmental quality. Use efficient and sustainable means is needed to meet the characteristics of the environment and the service most of the population lacking sewage treatment systems. In this perspective, anaerobic filters present themselves as one of the alternatives in the solution of these problems, since several studies show your efficiency and the low cost of your construction and maintenance. A variation in the use of this filter was proposed by Cynamon in 1986, with a series of three filters in ascending, descending and ascending streams, respectively. This study aimed to test Cynamon anaerobic filters for treatment of effluents from domestic activities. The raw sewage was treated in two of Cynamon filters adapted systems, with rising flows and another with streams. The raw and treated sewage were tested for pH, color, turbidity, temperature, cod and total coliforms and termotolerantes. It was possible to observe that the filter system on a pilot scale work and can be used later in other reviews of filters and NUSEA ancestors obtained best results about the parameters observed compared to the system.
