4 Styles of Aeration
High oxygen transfer surface aerators greatly improve water quality in ponds by dramatically agitating high volumes or water at the surface. These units are typically selected for surface aeration with a decorate fountain pattern is neither necessary nor desired. The white boil of highly aerated water focuses on maximum exposure of water to air for valuable gas exchange. High oxygen transfer surface aerators can also be used as deicers and will protect fish, boats and dock pylons from ice even in the coldest conditions.
Form & Function
Form and function surface aerators are designed to fit the needs of pond owners who wish to achieve a display pattern that is both aesthetically pleasing and an effective aerator. Form and function surface aerators produce a low pressure, but high volume discharge which boasts outstanding oxygen transfer rates. This is the most common type of surface aerator used by residential pond owners, as well as land developers seeking to block out commercial eyesores or mask the sound of highway traffic.
Aesthetically pleasing surface aerators are usually referred to as lake or pond fountains. Fountains typically utilize a centrifugal impeller to produce a high pressure, but low volume display pattern. Fountains are often designed to produce a very tall, attractive and eye-catching display. However, due to the reduced volume, a fountain may not be the best type of surface aerator for full time pond aeration needs. Most fountains of this variety are utilized in corporate parks or at subdivision entrances.
Diffused aeration is one of the most energy efficient means of aerating a pond or lake. These aerators push air to the bottom of the pond where diffuser stations break the air into small bubbles that rise to the surface. This constant flow of water disrupts the thermocline, vents off harmful gasses from the pond bottom and provides a larger usable area for the fish population, as oxygen levels increase throughout the body of water. Diffused aeration is an option even when electrical access is up to ¼ mile away from the water’s edge. This low profile aeration maintains the natural feel of a lake or pond, while increasing dissolved oxygen levels.
