This article provides an overview of emerging trends in environmental approaches to wastewater management in the developing world. Organic matter present in wastewater is one of the main sources of water pollution. In large amounts it can increase the number of microorganisms and thus the excessive consumption of dissolved oxygen in the metabolic processes of its utilization and stabilization, leading to the disappearance and extinction of aerobic organisms, favoring the appearance of other life forms in anaerobic conditions, often producing toxic residues. The main focus of this article is to analyze the presence of organic matter in urban sewage using a water quality model whose main parameters are dissolved oxygen and biochemical oxygen demand. Wastewater management methodologies can contribute to public health, sanitation, and improved conservation of water resources.
