2. Waste stabilization pond - Wikipedia

   en.wikipedia.org/wiki/Waste_stabilization_pond

   Maturation ponds offer aerobic conditions throughout, from the surface to the bottom. The main configurations of pond systems are: [4] [13] Facultative pond only; Anaerobic pond followed by a facultative pond; Facultative pond followed by maturation ponds in series; Anaerobic pond followed by a facultative pond followed by maturation ponds in ...

3. Organisms involved in water purification - Wikipedia

   en.wikipedia.org/wiki/Organisms_involved_in...

   Aquatic vegetation may provide similar surface habitat for purifying bacteria, protozoa, and rotifers in a pond or marsh setting; although water circulation is often less effective. Plants and algae have the additional advantage of removing nutrients from the water; but some of those nutrients will be returned to the water when the plants die ...

4. Water aeration - Wikipedia

   en.wikipedia.org/wiki/Water_aeration

   Subsurface aeration seeks to release bubbles at the bottom of the water body and allow them to rise by the force of buoyancy. Diffused aeration systems utilize bubbles to aerate as well as mix the water. Water displacement from the expulsion of bubbles will cause a mixing action to occur, and the contact between the water and the bubble will ...

6. Pond - Wikipedia

   en.wikipedia.org/wiki/Pond

   The technical distinction between a pond and a lake has not been universally standardized. Limnologists and freshwater biologists have proposed formal definitions for pond, in part to include 'bodies of water where light penetrates to the bottom of the waterbody', 'bodies of water shallow enough for rooted water plants to grow throughout', and 'bodies of water which lack wave action on the ...

7. Facultative lagoon - Wikipedia

   en.wikipedia.org/wiki/Facultative_lagoon

   Facultative lagoon (polishing pond) providing tertiary treatment after a constructed wetland in Hamburg-Allermöhe, Germany. Overflow from the facultative lagoon may be routed through one or more polishing ponds supporting lower populations of anaerobic micro-organisms and a higher proportion of aerobic organisms adapted to survival in lower concentrations of organic material.
