Aerators and fountains

The primary source of oxygen in ponds is the atmosphere, the air above the pond. Oxygen diffuses into the water from the air. As long as the water can be exposed to the air, then an ample supply of oxygen can enter the pond. One of the leading obstacles for the diffusion of oxygen into the water is stratification of the water column. Stratification occurs when the sun heats the surface water while deeper water remains cool. The warm and cool layers do not mix. This disrupts the circulation of oxygenated water from the surface of the pond to the bottom. While the warm surface water receives oxygen from the atmosphere as well as from photosynthesis of phytoplankton, the cooler bottom layer becomes depleted of oxygen. As the summer progresses, oxygen levels drop severely in the bottom layer.
Wastewater aeration is the process of adding air into wastewater to allow aerobic bio-degradation of the pollutant components. It is an integral part of most biological wastewater treatment systems. Unlike chemical treatment which uses chemicals to react and stabilize contaminants in the wastewater stream, biological treatment uses microorganisms that occur naturally in wastewater to degrade wastewater contaminants.
Aeration is the most critical component of a treatment system using the activated sludge process. A well designed aeration system or Aerator has a direct impact on the level of wastewater treatment it achieves. An ample and evenly distributed oxygen supply in an aeration system is the key to rapid, economically-viable, and effective wastewater treatment.
