High-Efficiency Nitrogen Removal

・By adopting a batch-type activated sludge method that enables multiple treatment processes within a single tank, we have successfully downsized the system.

・Intermittent dosing has made high-efficiency nitrogen removal possible.

・Automated electronic controls—such as float-type supernatant discharge devices with light sensors—significantly reduce maintenance compared to conventional batch-type systems.

Compliant with Wastewater Standards for BOD, COD, T-N, and T-P

・Coagulants are added to the batch-type reaction tank to enable advanced removal of phosphorus, suspended solids (SS), and other contaminants.

・The system allows for fine-tuned control of operating conditions, enabling site-specific optimization for superior treatment performance.
