The present study reviews sustainable alternatives for effluent treatment, comparing the conventional method and Nereda technology. It is believed that activated sludge does not promote adequate purification of the effluent, which can negatively impact the health of society and contribute to the degradation of water resources. However, Nereda technology is a sustainable approach that consists of a biological treatment using aerobic granular sludge. This produces extra purified effluents with little or no addition of chemicals in some cases. 28 references were analyzed, which indicated the most efficient alternative treatment in broad aspects, such as sedimentation and nutrient removal. In this way, technology offers greater health security and sustainability, ensuring the preservation of the environment. However, expanding it around the world is still a challenge, considering the factors that hinder its implementation.
