activated sludge process उदाहरण वाक्य

Also, variable flow of industrial waste associated with production cycles may upset the population dynamics of biological treatment units, such as the activated sludge process.
This discovery became known as the activated sludge process which is structured around the concept of bioaccumulation and is still widely used in wastewater treatment plants today.
B-stage, or bio-oxidation stage is a typical low-loaded activated sludge process, where biodegradation of the remaining organic material occurs.
It is also readily applied to the upgrading of existing flow-through activated sludge processes, by installing the attached growth reactors upstream of the aeration tank.
Attempts to improve the treatment process proved successful in 1914, when two chemists, Ardern and Lockett, discovered the Activated Sludge Process, which was soon in use worldwide.

Sand filters, lagooning and reed beds can all be used to reduce nitrogen, but the activated sludge process ( if designed well ) can do the job the most easily.
In addition, about 110 170 kg / ML of primary sludge is produced in the primary sedimentation tanks which most-but not all-of the activated sludge process configurations use.
Adsorption / bio-oxidation process is a two-stage modification of the activated sludge process consisting of a high-loaded A-stage and low-loaded B-stage.
One type of aerobic treatment system is the activated sludge process, based on the maintenance and recirculation of a complex biomass composed of micro-organisms able to absorb and adsorb the organic matter carried in the wastewater.
The activated sludge process produces about 70 100 kg / ML of waste activated sludge ( that is kg of dry solids produced per ML of wastewater treated; one mega litre ( ML ) is 10 3 m 3 ).
