Principais vantagens do reuso da água de lavagem dos filtros da ETA meia ponte, em Goiânia-Go, nos períodos de estiagem

Abstract

The reuse of backwash water from filters represents a strategic solution to optimize water resources in treatment plants, particularly in urban settings with high demand and limited resources. This study aimed to evaluate the technical, economic, and environmental advantages of reusing backwash water from the Meia Ponte Water Treatment Plant (WTP) in Goiânia. Quantitative assessments of wasted water volume were conducted, and analyses were performed to design the equipment needed for implementing a recovery and reuse system. The study also explored operational conditions and the benefits of reuse, such as reducing pressure on water sources, lowering operational costs, and enhancing system sustainability, particularly during drought periods. The results demonstrated that water reuse at the Meia Ponte WTP is not only feasible but also essential for ensuring water efficiency and mitigating environmental impacts. It is concluded that the adoption of this strategy is crucial for the development of a more sustainable and resilient urban water management system.
