How Wastewater Treatment Works
Wastewater treatment plays an essential role in addressing the contamination of water sources by pharmaceuticals and other pollutants.
When you send wastewater to a treatment plant, it undergoes several processes. First, large solids are removed through screening. Next, the water flows into sedimentation tanks, where heavier particles settle out.
Then, biological treatment occurs, using microorganisms to break down organic matter. Finally, disinfection methods, like chlorine or UV light, eliminate remaining pathogens.
Throughout this process, the treatment plant aims to reduce harmful substances, ensuring that the treated water is safe for release back into the environment or for reuse in various applications.
