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.

Sediments that settle out during water treatment?
sewage or sludge.
How much water is in sludge from a sewage treatment plant?
I may be wrong but i do believe there is 0.8% water in sludge 60% of the time, all the time.
How many different types of sludge are there?
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
What is sewage treatment?
Sewage sludge is the solids that are left over at the end of the sewage treatment process. The products of sewage treatment are: clean water which is released to the environment and sludge. Sludge consists mostly of cellulose (in the form of dead bacteria) and water. Cellulose is also what wood is made from; it does not decompose easily which is why the cellulose has not been broken down in the sewage treatment plant. The water content of sludge will vary from 30% water to 90% water depending on how much the sludge has been dewatered at the treatment plant. If you can imagine the appearance of a magazine after it had been through a food processor with just enough water to keep it soggy, that is what dewatered sludge will look like. Sludge should not be though of as concentrated sewage but it is still not safe to handle unless it has been processed in some way to kill harmful bacteria and viruses that are likely still living in the sludge. In North America most sewage sludge is sent to a landfill site; other options include further processing in 'Sludge Lagoons,' further biological processing and methane harvesting in an enclosed container; or processing into dry pellets for use on gardens. If sludge is sold to the public it will be heat processed and/or dried to kill bacteria. It will also be tested for contaminants such as dissolved metals that may be present in the raw sewage and not removed by the treatment process.
Which municipal waste treatment phase uses aerobic bacteria to decompose and digest waste solids?
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.
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.

Advantages and disadvantages of Activated sludge treatment plant?
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
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.
