Tratamento de água da chuva através da filtração lenta e desinfecção por radiação solar UV

Abstract

With the intense water scar city, or due to the lack of proper treatment to make it potable in some regions of Brazil, many people without sanitation contract water-related diseases. To the extent that this problem has spread over the years, solutions for rain water potabilization for consumption have been presented and many treatment techniques have been improved, bringing drinking water to populations that need it. With the intense water scarcity and the low quality of the water supply sources, in some regions of Brazil, many people do not have access to quality water, being exposed to many water borne diseases. With the worsening of this problem over the years, solutions to make rainwater potable for consumption have been proposed. Many treatment chniques have been improved, including slow filtration. The slow filtration, followed by UV radiation disinfection, is a technique that can beused for rainwater treatment, due it has good quality, basically requiring disinfection, in addition to being a cheap easy to operate technology. The aim of this study is to create Rainwater collected and stored by the buildings of the Federal University of Fronteira Sul (UFFS), Cerro Largo campus. The results indicate the elimination of total and thermotolerant coliforms by the use of this technology, confirming what is already reported in the bibliography. However, it is important to note that rain waters hold only beused for consumption when there is no other alternative of better quality, and the use of this technology for consumption purposes is only indicated for situations of water emergency.
