Overview
ETE LAGOA DAS MALVINAS is a secondary treatment plant serving 6,262 people in Mossoró, Rio Grande do Norte, Brazil. Contributing to local water quality management.
ETE LAGOA DAS MALVINAS is a wastewater treatment plant located in the Dom Jaime Câmara neighborhood of Mossoró, Rio Grande do Norte, Brazil. The plant serves a population of 6,262 residents, classifying it as a small-scale municipal facility within the semi-arid Northeast region of Brazil. The plant provides secondary treatment, which is the standard level required under Brazilian regulations (CONAMA resolutions) for most urban wastewater before discharge. The facility operates within the typical scale for a community of this size. Brazilian environmental legislation mandates that treated effluent meet quality standards to protect receiving water bodies. The treated wastewater from ETE LAGOA DAS MALVINAS is discharged into local watercourses that eventually drain into the Atlantic Ocean via the Apodi-Mossoró River basin. This region is characterized by seasonal rainfall and intermittent rivers, making proper wastewater treatment critical for maintaining water quality during dry periods and protecting downstream ecosystems.
Environmental context
The plant discharges into the Apodi-Mossoró River basin, which flows through the semi-arid Caatinga biome before reaching the Atlantic Ocean near the city of Areia Branca. This coastal zone includes mangrove ecosystems and estuarine habitats that support diverse aquatic life, including fish and crustaceans important for local fisheries. Proper secondary treatment helps reduce nutrient and pathogen loads, mitigating eutrophication risks in the downstream estuary.
Frequently asked questions
ETE LAGOA DAS MALVINAS is located at Rua José Rodrigues de Lima, in the Dom Jaime Câmara neighborhood of Mossoró, Rio Grande do Norte, Brazil.
The plant serves approximately 6,262 residents, making it a small-scale municipal wastewater treatment facility.
The plant provides secondary treatment, which is the standard required by Brazilian regulations for most urban wastewater before discharge into water bodies.
Brazil's wastewater treatment is regulated by CONAMA resolutions and the National Water Resources Policy. Plants of this scale are typically required to meet effluent standards for BOD, COD, and pathogens, with secondary treatment being the minimum for urban areas.
For small communities in Brazil, common secondary treatment technologies include stabilization ponds, anaerobic reactors (UASB), or activated sludge systems. The choice depends on local climate, land availability, and operational capacity.
