  2. Aerated lagoon - Wikipedia

    en.wikipedia.org/wiki/Aerated_lagoon

    There are two main types of submerged diffused aeration systems for lagoon applications: floating lateral and submerged lateral. Both these systems utilize fine or medium bubble diffusers to provide aeration and mixing to the process water. The diffusers can be suspended slightly above the lagoon floor or may rest on the bottom.

  3. Waste stabilization pond - Wikipedia

    en.wikipedia.org/wiki/Waste_stabilization_pond

    The following types of water and wastewater infrastructure may superficially resemble waste stabilization ponds, but are not the same: [citation needed] Aerated lagoons rely upon mechanical aerators to provide oxygen to stabilize organic matter. Aerated lagoons may be used as the first stage in the treatment line instead of anaerobic ponds to ...

  4. 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.

    en.wikipedia.org/wiki/Evaporation_pond

    An increasing demand for extracted products and treated wastewater will result in evaporation ponds expanding and related issues worsening until the depletion of these resources. [2] Evaporation ponds are found to increase green house gas emissions and therefore contribute to environmental issues like warming of the planet and ocean acidification .

    An integrated constructed wetland is an unlined free surface flow constructed wetland with emergent vegetated areas and local soil material. Its objectives is not only to treat wastewater from farmyards and other wastewater sources, but also to integrate the wetland infrastructure into the landscape and enhancing its biological diversity.

  9. Extended aeration - Wikipedia

    en.wikipedia.org/wiki/Extended_aeration

    Extended aeration agitates all incoming waste in the sludge from a single clarifier. The combined sludge starts with a higher concentration of inert solids than typical secondary sludge and the longer mixing time required for digestion of primary solids in addition to dissolved organics produces aged sludge requiring greater mixing energy input per unit of waste oxidized.
