This equalization tank treats beverage waste with a jet mixing and aeration system. Although the anaerobic tank is easily oxidized in 5-10 minutes, there is no need to use aeration (unless algae and other biological growth occurs). Mixing alone can be provided via recirculation pumps.
This tank for an aerobic digester in Ohio is mixed and aerated by an eddy mix jet aerator. The system was initially designed to run as an aerobic digestor, and was later converted to run as a sludge storage tank. The pumps and blowers are located outside the tank, which is now completely enclosed to prevent air emissions into the atmosphere.
This eddy jet mixer is shown during the start-up process. The mixer is located in a digestor tank and is designed to be operated as an anaerobic or aerobic digestor. Solids concentration can vary up to 4%.
