摘要

Brazil faces problems related to the large population which lives in the rural areas and discharges the wastewater directly into water bodies. This occurrence contributes not only to environmental damage but also to public health problems. In this case, the use of simple treatments would be beneficial, since the local wastewater could be treated with low cost and be built and operated by local labor even though it is not specialized. A system investigated in UNICAMP and which has these characteristics is, undoubtedly, the association of anaerobic filters with sand filters. The results from the research showed that the effluent had an organic matter concentration lower than the maximum permitted by Brazilian law (Brasil, 2005). Regarding the nitrogen compounds, the sand filters showed a great capacity of nitrification and, in reference to phosphorus, in the deepest depths (0.75 and 1.00 m), the removal was more than 98%.
