An aerated lagoon (or aerated pond) is a simple wastewater treatment system consisting of a pond with artificial aeration to promote the biological oxidation of wastewaters. [1] [2] [3] [4]
A lagoon is a shallow body of water separated from a larger body of water by a narrow landform, such as reefs, barrier islands, barrier peninsulas, or isthmuses. Lagoons are commonly divided into coastal lagoons (or barrier lagoons) and atoll lagoons. They have also been identified as occurring on mixed-sand and gravel coastlines.
A 353-hectare portion of the bay connected to the Rock Creek has been aerated using pipes since 2016. The system started as a large-bubble system intended mainly for de-stratification, creating a 74-ha oxic zone. It was upgraded in 2019 to fine-bubble injectors to provide more oxygen directly. [18]
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 limit release of malodorous gases, but with energy and maintenance requirements causing higher operating costs.
Also amphidrome and tidal node. A geographical location where there is little or no tide, i.e. where the tidal amplitude is zero or nearly zero because the height of sea level does not change appreciably over time (meaning there is no high tide or low tide), and around which a tidal crest circulates once per tidal period (approximately every 12 hours). Tidal amplitude increases, though not ...

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.
During a recent flight to San Juan, an airline passenger was asked to switch seats by three separate passengers as social media users chimed on Reddit about the indignity.
