The Blue Frog (BF) is our base circulator. It is a mixer and passive aerator that creates radial outflowing currents increasing the biological activity utilizing minimal energy consumption. The reason for the efficiencies is that the circulator does not lift water; it moves the water horizontally in the lagoon or pond. In a typical treatment system, this movement keeps the food and microbes in intimate contact. The Blue Frog System mimic's natures sustainable processes by using a series of circulators that are strategically placed in a lagoon or holding pond to layer the water and create a robust pycnocline or a cap that minimizes odor excursions. The Blue Frog System requires an engineered float depth of 4 feet.
