waste water engineering
Secondary treatment (Biological treatment)
🔸 Unit based on aerobic treatment
1. Trickling filter
2. Activated sludge process
3. Oxidation pond
🔸 Unit based on anaerobic treatment
1. Septic tank
2. Imhoff tank
3. USAB Reactors
🔸 Aerobic treatment of waste water
1. Suspended culture system
👉 In suspended culture system, Biomass is an suspension in the liquid containing organic matter.
👉 E.g. Activated sludge process.
2 Attached culture system
👉 In Attached culture system, biomass is attached to medium and sewage containing organic matter is passed through medium.
👉 E.g. Trickling filter, Rotating biological contactors, Biotowers etc.
