Stable, High-Performance Treatment Enabled by Unified Blower Piping
By completely rethinking the Johkasou design and arranging two carrier flow chambers in series, we have significantly enhanced treatment performance.
To further boost nitrogen removal efficiency, an intermittent metering pump has been introduced to control the circulation transfer pump.
Traditionally, biofiltration-type Johkasou systems required separate blower pipes for aeration and backwashing. However, through our patented backwash system, we have successfully unified this piping into a single system.
This innovation also greatly improves ease of maintenance and on-site workability.
