Which Aeration System is Best for You?
We utilize three unique technologies to address the specific aeration needs and goals of different water resources:

Diffused aeration is used to increase oxygen levels in relatively shallow lakes or reservoirs which are stratified to any degree or which experience anaerobic conditions in the winter months. In diffused aeration, compressed air is released through holes in diffuser lines placed near the bottom of the lake or reservoir.
 
The rising bubbles transfer oxygen to the water and transport bottom water to the surface, where direct contact with the atmosphere and photosynthesis continue the oxygenation process. The circulatory pattern created by the water flow also discourages the growth of algae species that prefer calm water or require adequate sunlight to proliferate.

In hypolimnetic aeration, oxygen-poor water just above the bottom sediment passes through an aerator, is oxygenated, and is returned to the bottom of the water body. This type of aeration is usually recommended for deeper bodies of water where destratification of the thermocline would be undesirable, as in the case of a water utility with a fixed bottom intake or to create or maintain a cold water fishery.

Metalimnetic Systems
In some rare cases, conditions in the metalimnion (thermocline) may warrant aeration either independently or in conjunction with hypolimnetic aeration. Similar in process to hypolimnetic aeration, metalimnetic aeration concentrates the oxygenation process in the metalimnion layer.
Depending on the specifications of your water resource, we will engineer a customized solution for your needs.
