Redução da vazão de água em torneira devido ao uso de arejadores

Abstract

The scarcity of water resources has driven the development of technologies aimed at more efficient water use. Among these solutions, faucet aerators stand out due to their simplicity, low cost, and potential for water savings. This study aimed to evaluate the effectiveness of aerators in reducing water flow in faucets through both theoretical and experimental approaches. A literature review was conducted to present the main types, working mechanisms, and advantages of these devices, while also contextualizing their relevance within the broader issue of water waste in Brazil. In parallel, an experimental analysis was carried out at the Technology Center of the Federal University of Paraíba (UFPB), where water flow from a faucet with and without an aerator was measured at three different opening levels, totaling 60 observations. The results showed a mean reduction in flow ranging from 32.8% to 39.0%, with statistical significance confirmed through Analysis of Variance (ANOVA). It is concluded that aerators are effective devices for water conservation and can be widely applied in households, institutions, and public spaces. The adoption of such systems is recommended as part of public policies focused on sustainability and efficient water resource management.
