Odor Mitigation (Hypolimnetic)

Get To The Bottom Of Your Odor Issues

Dissolved oxygen (DO) is an essential component of water chemistry and is even more important in reuse open reservoirs and other water bodies which can receive higher than normal BOD influent.  Oxygen gets into a reservoir primarily by diffusion across the air-water interface and from photosynthetic production (algae & submersed aquatic plants). DO depletion due to respiratory requirements of bacteria, algae, zooplankton, fish, etc. occurs throughout the water column but is more concentrated in deeper, dark waters and bottom sediments where organic matter and detritus accumulate and DO inputs are minimal.  Dead algae sinking to the bottom deplete available DO enabling the formation of hydrogen sulfide (H2S, the prime culprit for the "rotten egg" odor when exposed to air). Thermal stratification during summer months & under ice during the winter allows H2S to accumulate in bottom waters creating a perfect storm for a significant odor event during fall turnover and spring ice-out.

Hypolimnetic oxygenation keeps bottom waters sufficiently oxic which in turn keeps H2S from any attaining any significant accumulation in bottom waters.
