Sewage treatment is an important environmental process, responsible for cleaning wastewater before it is released into the surrounding environment. Through various treatment stages, raw sewage undergoes a transformation from a hazardous pollutant to clean and safe water.
The quality of water after sewage treatment can vary depending on the treatment processes employed and the local regulations. However, generally, water that has undergone sewage treatment undergoes a multi-step purification process that removes harmful contaminants, including:
Treated wastewater typically undergoes rigorous testing to ensure it meets environmental standards before being released. The resulting water is generally safe for use in irrigation, industrial processes, and even drinking water sources with additional treatment.
