After secondary treatment, the effluent typically undergoes further treatment or disinfection before it is discharged. This step is crucial for ensuring that any remaining harmful pathogens or contaminants are eliminated, making the water safe for release into the environment. Secondary treatment effectively reduces the amount of organic matter and suspended solids, but additional measures, such as chlorination, UV treatment, or ozonation, are often employed to ensure that all health and environmental standards are met.

The process of disinfection is particularly important because even after secondary treatment, some pathogens might still be present in the effluent. By disinfecting the effluent, wastewater treatment plants minimize the risk of contaminating nearby water bodies and protect public health.

Moreover, options that suggest direct release without further treatment ignore the potential risks associated with leftover contaminants. Similarly, indefinite storage would not be a practical solution for managing wastewater. Lastly, merely undergoing a chemical analysis does not address the need for treating the effluent to ensure its safety before discharge.
