It is the website of Kotobuki Kankyoh Kizai Co., Ltd. specialized in water treatment and wastewater treatment.

As advanced treatment, it is a device for removing muddy matter and organic matter in waste water.

· Automatic backwash mechanism realized complete automation.
· It is possible to efficiently adsorb and remove difficult organic matter.
· It is effective as tertiary treatment in strict regulations of effluent.

It adopts a hollow fiber membrane for solid-liquid separation of activated sludge and discharges a clear treated water.

· Secure water quality can be secured.
· The installation area is about half of the conventional method.
· Effective for reuse of water.

It is a device that removes pollutants in wastewater by allowing microorganisms to attach to a carrier made of resin and moving the carrier in a water bath by stirring effect by air.

· Depending on water quality, solid-liquid separation may be unnecessary, and operation management is easy.
· It is resistant to load fluctuation and stable operation can be maintained.

It is a device that biologically removes nitrogen contained in wastewater using specific bacteria (nitrifying bacteria / denitrifying bacteria).

It can propose according to wastewater conditions such as circulation type nitrification denitrification system and nitrification denitrification treatment using microorganism stuck carrier.

By using pure oxygen instead of air, it is possible to increase the metabolism of bacteria in the aeration tank and to operate at high load.

· The processing capacity is 2 ～ 3 times higher than the standard activated sludge method.
· Since it is possible to keep DO concentration high, it is resistant to load fluctuation.
· Small exhaust gas and splash, it realize clean treatment.

It is a treatment device that decomposes organic matter in wastewater by utilizing the metabolism of microorganisms such as bacteria and microanimals.

· Adopt treatment method suitable for scale and processing purpose from standard activated sludge system to contact material system
· Standard activated sludge system
· Bio fringe system
· Batch activated sludge system

It is a device that efficiently sediments and separates coagulated flocs in liquid.

· High speed sedimentation of cohesive flocs realized by original method.
· Becouse of high separation speed, it can be realize the space saving.
· Reducing the amount of flocculant used by about 30% compared with conventional type.

・Installation space
　　　　　　　=approximately 2.5m2
・Because it is compact, it can be installed in a small space.
・Simple operation is possible with automatic control panel. Daily operation management becomes easier than the conventional one, and operation is easy.
・No complicated construction work is required. All are installed on a standard base, construction is almost unnecessary.

It is an equipment which adsorbs coagulated floc in waste water to fine bubbles and forcibly floats and separates.

· Because separation speed is large, space reduction is realized.
· It is possible to generate ultra fine bubbles of high efficiency with the new system.
· Levitated scum has rich concentration and water recovery rate is high.
· Sediment sludge can be automatically discharged by adoption of lower rake.
· Automatic operation realized unmanned operation.
