ETE Bosque dos Palmares - Secondary Wastewater Treatment in Satuba, Alagoas

ETE Bosque dos Palmares is a wastewater treatment plant located in Satuba, within the state of Alagoas, Brazil. The facility serves a population of approximately 1,684 residents, providing secondary treatment to municipal wastewater. Situated near the coast, the plant plays a role in managing local water quality in a region characterized by tropical climate and proximity to the Atlantic Ocean. The plant operates with secondary treatment, which is appropriate for its small scale. In Brazil, wastewater treatment is regulated under national standards such as CONAMA resolutions, which set discharge limits for organic matter and nutrients. For small communities, secondary treatment is a common and effective approach to reduce pollution before discharge. The treated effluent is released into a local water body that eventually drains into the Atlantic Ocean. The coastal environment supports diverse marine life, including mangroves and estuaries that are ecologically sensitive. Proper treatment helps protect these habitats from nutrient enrichment and other pollutants.

The plant discharges into a local watercourse that flows into the Atlantic Ocean near the coast of Alagoas. This region features mangroves and estuarine ecosystems that provide nursery habitats for fish and crustaceans. The secondary treatment reduces organic load and suspended solids, helping to maintain water quality in the downstream coastal zone.
