Wastewater treatment is the process of removing contaminants and impurities from water that has been used in homes, industries, and businesses, transforming it into a cleaner state before it is released back into the environment or reused. This treatment involves a series of steps—physical, chemical, and biological—that work together to filter out harmful substances, including solids, chemicals, and pathogens. Overall, processed water plays a crucial role in a wide range of applications, ensuring that water meets the required quality standards for its intended purpose while also supporting sustainability and health objectives.
