Little John Digester Brochure

Source: DO2E

The Little John Digester is a state-of-the-art system that injects air through a spe-cially designed manifold system constructed of heavy duty non-corrosive material. Atop of this specialized manifold are stationary ridges or blades. As the air travels up and through the digester cylinder, a void is created. With this vacuum effect, solids are pulled in through the bottom of the digester and across the station-ary blades or ridges at the top of the unit. At speeds up to 65 feet per second, the solids are immediately emulsified when they come in contact with the blades or ridges resulting in a high degree of breakdown of solids, which greatly increases the digestion process. Ozone can also be injected in this cylinder which further facilitates the digestion process of raw sewage before it enters the wastewater plant. The Little John Digester uses THREE means of digestion: mechanical, chemical and biological.
