Activated sludge system

Activated sludge system utilize microbes in nature and is the most popular treatment method and applied for treatment of organic substance contained wastewater.
It is available fixed-bed type set each module in aeration tank or compact sized batch-wise type and so on.

<< Applications >>

• Urban wastewater/apartment complex wastewater
• Food-processing wastewater/livestock wastewater
• Chemical plant wastewater

Air added floatation system

Contrary to coagulation-sedimentation method, air added floatation is flotation-separation method which attaches fine air bubbles with suspended solids, and it is possible to downsize the system.

<< Example of application >>

• Metal-surface treatment waste water
• Dyeing/ oil-containing wastewater
• Laundry wastewater
• Painting waste water etc.

pH neutralization system

The pH neutralizing system is used for the boiler blow waste water treatment and the neutralizing processing of the alkaline waste water such as the cement plants.

<< Features >>

• Processing for both direction or one of the acid or the alkali drain is possible.
• The system becomes a unit type and doesn't choose the installation location. The site work can be omitted and the labor saving is possible.

Membrane bioreactor system

Membrane bioreactor system can conserve its installation space for the facility as well as securing stable high-quality treatment water.
The operation and maintenance can be easy and the treat water be recycled.

<< Features >>

• The sedimentation basin becomes unnecessary. Moreover, the capacity of the reaction tank can be reduced.
• Completely removable the solids bigger than pore diameter of membrane (cryptosporidium etc.)
• The membrane area for each module is large, and the installation and the operation and maintenance are easy.
• The membrane can be detached easily from module part.
