Secondary Treatment
Secondary treatment is a crucial step in wastewater treatment that focuses on removing dissolved organic matter and nutrients from sewage after primary treatment. It typically involves biological processes using microorganisms, such as bacteria, to break down pollutants. In this stage, air is often introduced to help these microorganisms thrive, effectively cleaning the water. After treatment, the water is clearer and contains fewer harmful substances, making it safer for discharge into the environment or for reuse. The goal is to improve water quality and minimize the impact on ecosystems and public health.
