Resumen:

Biological treatment of wastewater leverages the power of microorganisms to purify domestic and industrial effluents. Key processes include the conversion of carbon, organic, and nitrogen compounds, sulfate reduction, denitrification, and the fermentation of methane and volatile fatty acids. These microbial activities clean the water but also produce valuable biosolids, biogases, and protein compounds that can be recovered and reused. Microorganisms such as bacteria, fungi, algae, and archaea are central to these processes. They thrive in diverse nutrient and physicochemical conditions, enabling the degradation and remodeling of pollutants. The advantages of biological treatment span technical, economic, and environmental aspects, offering a sustainable solution to manage a wide range of organic contaminants. Wastewater treatment involves a sequence of physical, chemical, and biological steps to effectively separate and remove impurities. The importance of this treatment is universally recognized, particularly for water destined for human consumption. Rapid industrial growth and population increases have intensified the demand for clean water, yet a significant portion of available resources is saline or contaminated. Pollution from organic and inorganic substances further complicates conventional treatment methods, making biological processes crucial for efficient contaminant removal. Innovative biotechnological approaches inspired by natural microbial processes have expanded the potential for environmental decontamination. These methods offer significant benefits for human health, agriculture, energy, and overall environmental protection. Understanding and harnessing the biological capacities of microorganisms is key to developing more effective and sustainable wastewater treatment strategies. © 2025 Bentham Science Publishers.
