Features
Stable, Advanced Treatment Performance Featuring Unified Blower Piping
By rethinking Johkasou design from the ground up, and positioning two carrier flow chambers in series, treatment performance has been dramatically improved. An intermittent metering pump has also been adopted for the circulation transfer pump in order to increase nitrogen removal performance. In addition, up to now biofiltration-type Johkasou required two blower pipes for aeration and backwashing, however we have succeeded in the unification of this piping in the Johkaou through our patented backwash system. Workability has also been greatly improved.
