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.

The water content in sludge from a sewage treatment plant typically ranges from 70% to 98%, depending on the type of treatment process used and how dewatered the sludge is. The remaining percentage consists of solids, which can include organic matter, inorganic materials, and pathogens.
3 types: Sewage sludge Septic tank sludge Industrial sludge ------- The term "sludge" is used in different disciplines to mean different things. For example, there is sewage sludge industrial sludge metal sludge gallbladder sludge engine sludge the muddy gunk on the bottom of a stream or river slushy ice on the ocean an agglutination or aggregation of blood cells
Lime sludge is a byproduct of the water treatment process that involves adding lime to water to adjust its pH level. It is a soft, white, chalky solid that settles at the bottom of water treatment tanks. Lime sludge needs to be properly disposed of to prevent environmental contamination.
The municipal waste treatment phase that uses aerobic bacteria to decompose and digest waste solids is called the biological process or the activated sludge process. In this process, wastewater is mixed with bacteria-rich sludge in an aerated tank, creating an oxygen-rich environment that promotes the growth of aerobic bacteria. These bacteria break down and digest the organic matter in the waste solids, resulting in the purification of the wastewater.
Sewage treatment is the process of removing contaminants and pollutants from wastewater before it is released back into the environment. It typically involves physical, biological, and chemical methods to reduce the harmful effects of untreated sewage on public health and the environment. The goal is to produce treated water that is safe to be discharged or reused.
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.

Advantages of Activated Sludge ProcessLow installation costGood quality effluentLow land requirementLoss of head is smallFreedom from fly and odor nuisance high degree of treatmentDisadvantages of Activated Sludge ProcessNot 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 highSludge disposal is required on large scaleThis process is sensitive to certain industrial wastesSkilled supervision is required to check that the returned sludge remains active
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.
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.
