Lake aerators and Fountains :
Water aeration is often required in water bodies that suffer
from anoxic conditions, usually caused by adjacent human activities
such as sewage discharges, agricultural run-off, or over-baiting a
fishing lake.
Aeration can be achieved through the infusion of air into the bottom of the lake, lagoon or pond or by surface agitation from a fountain or spray-like device to allow for oxygen exchange at the surface and the release of noxious gasses such as carbon dioxide, methane or hydrogen sulfide.
Dissolved oxygen (DO) is a major contributor to water
quality. Not only do fish and other aquatic animals need it, but
oxygen breathing aerobic bacteria decompose organic
matter.
When oxygen concentrations become low, anoxic conditions may
develop which can decrease the ability of the water body to support
life.
