Impact of Wastewater Treatment Plants: An Assessment from Environmental Engineering

The study analyzed the environmental performance and operational efficiency of wastewater treatment plants from an environmental engineering perspective, aiming to identify the impacts associated with their functioning and technological level. The methodology included direct observation of unit processes and a systematized analysis of operational information, applying technical criteria for environmental assessment and contaminant removal. The results showed significant differences among the plants, highlighting one system with suspended solids removal efficiency below 65%, associated with high environmental impact, in contrast to others with efficiencies above 90% and moderate effects. It is concluded that environmental performance depends on technological level, emission control, and integrated waste management.
