| dc.description.abstract | The main orientation for the population was social distance and as a way of meeting this orientation without stopping public services and companies, a considerable part of the workers adopted remote work. To assess the impact of the pandemic on the operation of the municipal wastewater treatment, it was necessary to seek data from several sources of information. Centrally the monitoring data of the treatment operation were used flow measurements, DBO520°C and ammoniacal nitrogen from the last two years were compiled. If, on the one hand, the consumption of treated water increased in residential branches during the pandemic period compared to the reference period in the order of 3%, the situation in the branches of the other categories goes in the opposite direction with a 19% drop during the pandemic period. The proportion between residential consumption and other consumption increased during the pandemic. With the population staying more at home and the decrease in commercial, industrial and public service activities of the Sanitary sewer system Navegantes – SES Navegantes. Through the analysis of the impacts of social detachment in the first COVID-19 outbreak, it is possible to predict how and in what way the generation of sewage and its physicochemical characteristics can respond to similar measures of containment in new outbreaks of the disease. | pt_BR |
