How the Aeration Process WorksLake Bed Aeration is the introduction of compressed air to a water body. When released at the bottom of a pond or lake, compressed air naturally begins to migrate towards the surface of the water. As air travels up the water column the pressure surrounding the bubbles slowly decreases causing the bubbles to increase in size -- a slight current begins to develop. The current draws oxygen-depleted water from the bottom and transports it to the surface. This action protects fish, aquatic organisms and beneficial bacteria from suffocation by breaking down stratified waters while increasing dissolved oxygen levels. Unlike a sewerage digester, in a pond/lake, the greatest portion of the oxygen transfer takes place as the bottom water spreads across the surface and exchanges gases with the atmosphere. The actual transfer of oxygen from the bubbles is quite insignificant. |
Nutrient Pollution of your lake or pond: (Source
EPA email news release Jan 15, 2010) "Nutrient
pollution can damage drinking water sources; increase exposure to harmful algal
blooms, which are made of toxic microbes that can cause damage to the nervous
system or even death; and form byproducts in drinking water from disinfection
chemicals, some of which have been linked with serious human illnesses like
bladder cancer. Phosphorus
and nitrogen pollution come from stormwater runoff, municipal wastewater
treatment, fertilization of crops and livestock manure. Nitrogen also forms from
the burning of fossil fuels, like gasoline.
Nutrient
problems can happen locally or much further downstream, leading to degraded
lakes, reservoirs, and estuaries, and to hypoxic “dead” zones where aquatic
life can no longer survive. High amounts of nitrogen and phosphorus in surface
water result in harmful algal blooms, dead fish, reduced mating grounds and
nursery habitats for fish."
