Aerobic Process	Anaerobic Process
• If air or oxygen is available freely to the waste water in dissolved form then aerobic decomposition will occurs.	• If free dissolved oxygen is not available to the sewage then anaerobic decomposition will occur.
• It’s caused by anaerobic bacteria as well as facultative bacteria operating aerobically.	• Its caused by anaerobic bacteria as well as facultative bacteria operating anaerobically.
• In this process kinetic reaction relative fast.	• In this process kinetic reaction relative slow.
• Post treatment- typically direct discharge.	• Invariably followed by aerobic treatment.
• Relatively large in size.	• Small & compact in size.
• No smell is generated.	• It is generates foul gases.
• End product requires some treatment.	• Well stabilized end products
• End products are CO2, H2O, no methane gas recover.	• CH4, CO2, H2S etc methane gas which combustible & can be used as fuel.
