High-Efficiency Nitrogen Removal

・We achieved downsizing of the tank by adopting a batch-type activated sludge method that performs various treatments in a single tank.

・The adoption of an intermittent dosing method has enabled high-efficiency nitrogen removal.

・Automated electronic controls, such as a float-type supernatant discharge device with a light sensor, have significantly reduced the complex maintenance tasks commonly associated with conventional batch-type activated sludge systems.

Complies with various wastewater regulations for BOD, COD, T-N, and T-P values

・Coagulants are added to the batch-type reaction tank to achieve high-level removal of phosphorus, SS, and other contaminants.

・The system allows for more precise adjustment of operating conditions, enabling optimal treatment tailored to each site.
