Estudo dos impactos diretos do lançamento inadequado de águas de lavagem de filtros (alf) – estudo de caso Siaa da Zona Fumageira – Bahia

Abstract

Water is one of the most important natural resources for maintaining life on the planet, but despite this, it is clear that it has been poorly managed and that is why problems such as contamination of water sources and excessive losses in the system occur. This work records a case study in the Integrated Water Supply System (SIAA) of the Fumageira Zone, whose treatment plant, since its implementation, has been disposing of waste inappropriately. Thus, the objective was to study the direct impacts of the disposal of filter washing water (ALF's) from the SIAA water treatment plant in the Smoke Zone and evaluate the possibilities of sustainable disposal of this waste. Through analyzes of the characteristics of filter washing waters, as well as the granulometric composition, fertility nutrients and heavy metals of the soil in the area of ​​influence of incorrect disposal, it was possible to measure that, although the final destination of the ETA effluents is not in accordance with the As indicated by Brazilian legislation, there is no evidence of soil contamination, although it is clear that there is uneven growth of vegetation where there is interaction with ALF's. The research also revealed that the circumstances of inappropriate disposal do not occur due to a lack of information from the service provider company, and that there are possibilities to correct the situation, with short and long-term actions.
