Advanced Nitrogen Removal Preventing
Wetland Eutrophication

Stable, advanced nitrogen removal has been realized through the circulation of nitrification liquid through the anaerobic chamber even during aeration, in addition to nitrogen removal through anaerobic agitation. This contributes to the prevention of eutrophication of oceans, rivers and wetlands.

Phosphorous Removal Through
Biological Dephosphorization

For this system we adopted a phosphorous removal method that utilizes the work of microorganisms. Large ancillary equipment for phosphorous removal is not required.
* Please note that since the dephosphorization function is largely influenced by the properties of the inflowing raw water, complementary flocculant addition equipment is installed. In cases when performance is insufficient, flocculant will be added in order to stabilize phosphorous removal.
* The tank length measurement includes the single-side 80mm flange.
