Who ranks for “wastewater treatment”

Wastewater treatment cleans used water from homes and businesses so it can safely return to the environment or be reused.

Purpose

Protect health: Removes harmful germs and bacteria that cause disease. Save nature: Keeps dirty water, chemicals, and extra nutrients out of rivers and lakes. Reuse water: Creates clean, recycled water for watering plants and industrial use.

Main Stages

Pre-treatment: Uses large metal screens and grit tanks to pull out big trash, wipes, sand, and rocks. Primary treatment: Slows the water down in large tanks so heavy solids sink to the bottom (sludge) and oils float to the top (scum). Secondary treatment: Uses helpful bacteria in aerated tanks to break down tiny pieces of organic waste and clear out nutrients. Tertiary treatment & Disinfection: Filters the water and uses ultraviolet (UV) light or chlorine to kill any remaining germs before release.
