Activated Sludge Process | IWA Publishing
Activated sludge (AS) is a process dealing with the treatment of sewage and industrial wastewaters and developed around 1912-1914. There is a large varity of design, however, in principle all AS consist of three main components: an aeration tank, which serves as bio reactor; a settling tank ("final clarifier") for seperation of AS solids and treated waste water; a return
We offer a range of mobile sludge dewatering options for dealing with waste water treatment, settlement pond and filter bed waste. Using AVC dewatering units, mobile decanters and mobile centrifuge plants, dewatering will result in a substantial volume reduction of sludge, with solid content ranging from 10% to 15% or higher in some cases.
Activated Sludge - Activated Sludge Process,Types
Activated sludge is a suspended growth process, commonly employed to handle human waste and industrial waste in wastewater treatment plants. This process was invented by two British engineers, Edward Ardern and W.T. Lockett in an attempt to cope up with wastewater on a large scale in a hygienic and efficient way.

Waste Water Treatment Activated sludge process. The Activated Sludge Process is the one of the main in ( sewage treatment ) waste water treatment process. Activated sludge process was developed in England in 1914 and was so named because it involved the production of an activated mass of microorganisms capable of aerobically stabilizing the organic content of a waste water.

- Initially, most researchers utilized ammonium sulfate as the dispersion medium for polymerization. Zheng et al . prepared a stable cationic polyacrylamide aqueous dispersion using poly (2-methylacryloylxyethyl trimethylammonium chloride) (DMC) as the dispersion stabilizer and potassium persulfate-sodium sulfite as the initiator.
- Can polyacrylamide aqueous dispersion be soluble after polymerization?
- However, after polymerization, the resulting copolymer should not be soluble in the dispersion medium. The first non-ionic monomer used in aqueous media was acrylamide, which can be copolymerized with anionic and cationic monomers to produce an ionic polyacrylamide aqueous dispersion system .
- What are the different types of anionic polyacrylamide synthesis technologies?
- The paper lists six different kinds of anionic polyacrylamide synthesis technologies, including homopolymerization posthydrolysis process, homopolymerization cohydrolysis process, copolymerization approach, inverse emulsion polymerization, precipitation polymerization and radiation polymerization.
- What is the molecular weight of a polyacrylamide dispersed system?
- The resulting polyacrylamide dispersed system exhibited a molecular weight of up to 1.05 × 10 7 g·mol −1, indicating significant stability. Zhao et al . utilized dispersion polymerization to synthesize polyacrylamide, employing an aqueous solution of ammonium sulfate and sodium chloride as inorganic salts.
