- Low installation cost
- Good quality effluent
- Low land requirement
- Loss of head is small
- Freedom from fly and odor nuisance high degree of treatment
- Not very flexible method (If there is sudden increase in the volume of sewage or if there is sudden change in the character of sewage, there are adverse effects on the working of the process and consequently the effluent of bad quality is obtained).
- Operation cost is high
- Sludge disposal is required on large scale
- This process is sensitive to certain industrial wastes
- Skilled supervision is required to check that the returned sludge remains active

Activated sludge technology was used in what Michigan community?
Both Lansing, MI and Howell, MI have used activated sludge wastewater treatment. However, the first experimental plant in the US was built in Milwaukee (Wisconsin) in 1915.

Does activated sludge form a lacy network of floc mass that entraps many materials not used as food?
Yes, activated sludge forms a lacy network of floc mass that can entrap various materials, including not only food sources but also non-biodegradable substances and inert particles present in the wastewater. This entrapment allows for the removal and treatment of these materials during the sludge treatment process.
Who invented sewage treatment?
The Activated Sludge Process for the Sewage treatment which is well known and widely used was first invented by Edward Ardern and William Lockett in 1914.

What is RAS in a sewage treatment plant?
RAS, or Return Activated Sludge, is a process in sewage treatment plants where a portion of the activated sludge from the secondary clarifier is recycled back to the aeration tank. This recycling helps maintain a high concentration of microorganisms, which are essential for breaking down organic matter in wastewater. By returning RAS, the efficiency of the treatment process is enhanced, allowing for better removal of pollutants before the treated water is discharged or further processed.

How purify water obtained after activated sludge treatment?
usually water from a activted sludge process treatment will be free of organic carbon, they generally contain nitrogenous, phosphate and inorganic wastes, and those nutrients could be treated by simultaneous nitrification and denitrification process. the treated water from activated sludge process and denitrification process would be virtually free of pollutants. usually water from a activted sludge process treatment will be free of organic carbon, they generally contain nitrogenous, phosphate and inorganic wastes, and those nutrients could be treated by simultaneous nitrification and denitrification process. the treated water from activated sludge process and denitrification process would be virtually free of pollutants.
