Sewage treatment involves screening debris, settling suspended particles, anaerobic digestion of sludge to produce methane, aeration for aerobic digestion, and chlorination to kill microorganisms.
Il trattamento delle acque reflue prevede la rimozione di detriti, la sedimentazione delle particelle sospese, la digestione anaerobica del fango per produrre metano, l'aerazione per la digestione aerobica e la clorazione per uccidere i microrganismi.
| Front | What is the process of sewage treatment? |
|---|---|
| Back | Water is screened to remove large debris, Suspended particles are settled by gravity, Organic matter is settled by gravity and becomes sludge, Sludge is digested anaerobically to produce methane, The remaining liquid is aerated to encourage aerobic digestion, Chlorination kills microorganisms, making it safe to drink. |
