What are trace contaminants in sewage treatment?

Trace contaminants in sewage treatment refer to pollutants that are present in very low concentrations but can significantly impact water quality. These contaminants may include pharmaceuticals, personal care products, heavy metals, and other industrial chemicals. Despite their low concentration, trace contaminants can pose risks to aquatic ecosystems and human health due to their potential toxicity and ability to accumulate in the environment.

Understanding these contaminants is critical in wastewater management because traditional sewage treatment processes may not be designed to effectively remove them. As awareness of their impact grows, there is an increasing focus on advanced treatment technologies that target these trace pollutants to protect water sources and the environment.
