Biologically active floc from aeration and settling sewage and / or organic matter.
Biological treatment process used to convert organic material in wastewater into carbon dioxide.
Aktiivilietelaitos Aktivslamanläggning A waste water treatment method using a three stage biological method. Stage I is undertaken anaerobically. Stage II uses an aeration basin in which microbe containing sludge is added. Sludge is separated from the waste water in (Stage III). Part of the sludge is removed and part (the activated sludge) is returned to the aeration basin.
An active population of microorganisms used to treat wastewater, or the process in which the organisms are employed.
Sludge withdrawn from the secondary clarifier in the activated sludge process, consisting of micro-organisms, nonliving organic matter and inorganic materials.
Sludge particles produced in raw or settled wastewater (primary effluent) by the growth of organisms (including zoogleal bacteria) in aeration tanks in the presence of dissolved oxygen. The term “activated” comes from the fact that the particles are teeming with bacteria, fungi, and protozoa. Activated sludge is different from primary sludge in that the sludge particles contain many living organisms that can feed on the incoming wastewater.
Sludge with active, live degradation micro-organisms.
sludge particles produced by the growth of microorganisms in aerated tanks as a part of the process to treat wastewater.
The biological process that removes organic matter from wastewater using microscopic plants and animals (organisms). The activated sludge process imitates the natural process that a river, lake or stream uses to clean itself.
Flocculent sludge produced by the growth of bacteria and other organisms in raw or settled sewage, when it is continuously aerated.
The biologically active solids in an activated sludge process wastewater treatment plant.
Term given to a method of wastewater treatment that uses aerobic and facultative bacteria in suspension to remove wastes. Activated sludge is a popular method of treatment, and dozens of variations on the basic process exist.
The term "activated sludge" refers to a brownish flocculent culture of organisms developed in aeration tanks under controlled conditions. It is also Sludge floc produced in raw or settled waste water by the growth of zoological bacteria and other organisms in the presence of dissolved oxygen. Activated sludge is normally brown in colour.
Sewage sludge that is treated by forcing air through it in order to activate the beneficial microbial populations resident in the sludge.
Aerated sludge that is subjected to bacterial processes.
1) the biological solids produced in an activated sludge basin (secondary wastewater treatment). 2) sludge floc produced by the growth of zoogleal bacteria and other organisms in the presence of oxygen and accumulated in sufficient concentration by returning floc previously formed.b
Sludge with active, live degradation microorganisms.
Product that results when primary effluent is mixed with bacteria-laden sludge and then agitated and aerated to promote biological treatment, speeding the breakdown of organic matter in raw sewage undergoing secondary waste treatment.
(1) the flocculent mass of microorganisms, mainly bacteria, that develops when sewage or liquid effluent is aerated; (2) a continuous process in which a liquid effluent is aerated in a tank to reduce the BOD and ammoniacal nitrogen
The process by which healthy bacteria (the activated sludge solids) act to digest sewage. Where a Fixed or floating media (see below) are used, bacteria that falls off the media is returned to the treatment system by aeration from below.
Activated sludge is a process in sewage treatment in which air or oxygen is forced into sewage liquor to develop a biological floc which reduces the organic content of the sewage. In all activated sludge plants, once the sewage has received sufficient treatment, excess mixed liquor is discharged into settling tanks and the supernatant is run off to undergo further treatment before discharge. Part of the settled material, the sludge, is returned to the head of the aeration system to re-seed the new sewage entering the tank.
