Avaliação da sazonalidade do fenômeno da primeira carga de lavagem em um sistema de captação e armazenamento de águas pluviais

Abstract: RESUMO O escoamento superficial de áreas urbanas é capaz de transportar poluentes para os sistemas de armazenamento de água. O objetivo deste trabalho foi avaliar a concentração de poluentes no dispositivo de separação inicial, denominado first flush (FF), e no reservatório (RR), conforme as estações do ano, em amostras de água de chuva, por meio da Concentração Média do Evento (CME) e das curvas M(V). A metodologia consistiu na análise de 68 amostras coletadas em um sistema de águas pluviais (SAP) na cidade d… Show more

“…5 Although each year there has been an average increase, (ranging from 13% to 20%) in the number of publications in scientific periodicals regarding the issue of harnessing rainwater and assessing the quality of rainfall, there have been few studies explaining the role of seasonal factors, through wet and dry deposition at different sampling points of the catchment area and the storage of water in rainfall systems. Zhang et al 9 and Souza et al 10 provide the seasonal results obtained from an analysis of the parameters of the quality of rainfall collected at a single point of the system and that have different positive features. The objective of this study is to characterize the rainwater on the basis of samples collected at 4 different points of a catchment and storage system of rainfall located in the city of Rio de Janeiro.…”
