Update: 2025-07-21
Description
In this episode, we outline the essential stages of sewage treatment.
Proper disposal of waste water is crucial for environmental protection.
Initially, screening removes large debris, followed by sedimentation which separates solids (sludge) from liquid (effluent).
Subsequently, bacteria anaerobically digest the sludge, while the effluent undergoes aerobic digestion, preparing it for safe environmental release.
