Tertiary Treatment
Tertiary Treatment is the final and most advanced stage of cleaning wastewater before it's released back into the environment or reused. Think of it as the "polishing" step after the main cleaning processes. While primary treatment removes solid materials and secondary treatment handles biological waste, tertiary treatment focuses on removing any remaining impurities, chemicals, and microscopic contaminants. This process is becoming increasingly important as environmental standards become stricter and water reuse becomes more common. You might also see it called "advanced treatment," "advanced water treatment," or "water polishing" in job descriptions.
