Oxidation ditch equipment

Submersible propeller OD system

The oxidation ditch process is the mainstream method of small-scale  sewage treatment system because the process is capable of stably steadily handling fluctuations in the load of inflow sewage water and is easy to maintain. JFE Engineering’s submersible propeller OD (oxidation ditch) system is an aeration system that combines a submersible propeller and a diffuser. Since the submersible propeller and the diffuser are independently installed, the system can easily respond to load fluctuations and initial operation, and easily switch the operation mode between anaerobic and aerobic, and is also capable of performing de-nitrification. The system can also operate in a deep tank with a diffuser.  The system aims at both space saving and energy saving.
