Submersible mixer

The submersible mixer is operated by an electric motor, which is coupled to the mixer's propeller, either direct-coupled or via a planetary gear-reducer. The propeller rotates and creates liquid flow in the tank, which in turn keeps the solids in suspension. The submersible mixer is typically installed on a guide rail system, which enables the mixer to be retrieved for periodic inspection and preventive maintenance.^[2]

Examples of applications where submersible mixers are commonly applied:^[3]

• Anoxic/anaerobic tanks and oxidation basins (activated sludge) at sewage treatment plants^[4]
• IFAS, MBBR, and other fixed film biocarrier processes.
• Mixing of sewage wet wells
• Reception tanks and post-digestion tanks at biogas facilities
• Liquid Manure storage tanks at dairy, hog, and poultry farms
• Waste processing at slaughterhouses, poultry abattoirs, fish processing plants, etc.
